Object Oriented Analysis points to remember

noreply@blogger.com (Raj) — Wed, 07 Dec 2016 11:37:00 +0000

Encapsulate what varies.

Code to an interface rather than to an implementation.

Each class in your application should have only one reason to change.

Coding to an interface, rather than to an implementation, makes your software easier to extend.

By Encapsulation what varies, you make your application more flexible, and easier to change.

When you have a set of properties that vary across your objects, use a collection, like a Map, to store those properties dynamically.

You’ll remove lots of methods from your classes, and avoid having to change your code when new properties are added to your app.

Most good designs come from analysis of bad designs.

Never be afraid to make mistakes and then change things around.

Seeing how easy it is to change your software is one of the best ways to figure out if you really have well-designed software.

Cohesive class does one thing really well and does not try to do or be something else.

Cohesion measures the degree of connectivity among the elements of a single module, class, or object.

The higher the cohesion of your software is, the more well-defined and related the responsibilities of each individual class in your application. Each class has a very specific set of closely related actions it performs.

Cohesion focuses on how you’ve constructed each individual class, object, and package of your software.

If each class does just a few things that are all grouped together, then it’s probably a highly cohesive piece of software. But if you have one class doing all sorts of things that aren’t that closely related, you’ve probably got low cohesion.

Use basic OO principles like encapsulations and inheritance to make your software more flexible.

Make Sure each of your classes is cohesive and should focus on doing ONE THING really well.

Always strive for higher cohesion as you move through your software’s design life cycle.

You solve big problems the same way you solve small problems.

Strive for a maintainable, reusable design.

By encapsulating what varies, you make your application more flexible, and easier to change.

Coding to an interface, rather than to an implementation, makes your software easier to extend.

Get features from the customer, and then figure out the requirements you need to implement those features.

Architecture is the organisational structure of a system, including its decomposition into parts, their connectivity, interaction mechanisms, and the guiding principles and decisions that you use in the design of a system.

Sometimes the best way to write great code is to hold off on writing code as long as you can and Plan,organise,architect,understand requirements,reduce risks all these make the job of actually writing your code very simple.

Absolutely! Remember,great software is more than just great code.

A design principle is a basic tool or technique that can be applied to designing or writing code to make that code more maintainable, flexible, or extensible.

First design principle is the OCP, or the Open-Closed principle. The OCP is all about allowing change, but doing it without requiring you to modify existing code.

Open-Closed Principle Classes should be open for extension, and closed for modification.

Java + How to create Synchronized Map ?

noreply@blogger.com (Raj) — Fri, 05 Feb 2016 07:38:00 +0000



Hash Map class Structure

Class HashMap

java.lang.Object

java.util.AbstractMap

java.util.HashMap




Creating SynchronizedMap

Map m = Collections.synchronizedMap(new HashMap(...));

Points to remember about HashMap

1) Permits null values and the null key. 

2) HashMap class is equivalent to Hashtable, except that it is unsynchronized and permits nulls.

3) It does not guarantee that the order will remain constant over time

4) An instance of HashMap has two parameters that affect its  performance: initial capacity and      

    load factor. 

5) The capacity is the number of buckets in the hash table, and the initial capacity is simply the   

    capacity at the  time the hash table is created. 

6) The load factor is a measure of how full the hash table  is allowed to get before its capacity is 

    automatically increased.

Difference between Comparable and Comparator Interface

noreply@blogger.com (Raj) — Mon, 28 Dec 2015 10:40:00 +0000

Comparable
1) Comparable is an interface.

2) Comparable is located in the java.lang package

3) It is in the collections framework of java since java 1.2.

4) Its author is Josh Bloch.

5) Comparable interface contains one methos i.e "int compareTo(Object o)" to implement.

6) It compares this object with the argument object for sorting order. and it returns the
negative integer or zero or positive integer value based on this object is greater than
or equal to the specified argument object.

7) It throws ClassCastException if the specified object prevents it from being compare to this object.

8) Except Number class most of the

Interface

package java.lang;
import java.util.*;
public interface Comparable {
public int compareTo(T o);
}

Example:

/**
* @author raj
*
*/
public class Planet implements Comparable{
private int size;
private String name;

public Planet(String name, int size) {
this.setName(name);
this.setSize(size);
}

public int compareTo(Planet planet) {

return this.getSize() == planet.getSize() ? 0
: this.getSize() < planet.getSize() ? -1
: 1;

}

public String toString() {
StringBuilder builder = new StringBuilder();
builder.append(getName());
builder.append(" : ");
builder.append(getSize());
return builder.toString();
}

public int getSize() {
return size;
}

public void setSize(int size) {
this.size = size;
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}
}

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;

public class PlanetEngine {
public static void main(String[] args) {
Planet p0 = new Planet("sun",0);
Planet p1 = new Planet("mercury",1);
Planet p2 = new Planet("venus",2);
Planet p3 = new Planet("earth",3);
Planet p4 = new Planet("mars",4);
Planet p5 = new Planet("saturn",5);
Planet p6 = new Planet("jupiter",6);
Planet p7 = new Planet("uranus",7);
Planet p8 = new Planet("neptune",8);
Planet p9 = new Planet("pluto",9);

List list = new ArrayList();
list.add(p0);
list.add(p1);
list.add(p2);
list.add(p3);
list.add(p4);
list.add(p5);
list.add(p6);
list.add(p7);
list.add(p8);
list.add(p9);

System.out.println("\n\nSORGING BYE SIZE USING COMPARABLE ");
Collections.sort(list);

for(Planet p : list) {
System.out.println(p);
}
}
}

In this example the compare to method returns the negative , zero, or positive integer values based on the size of the planet. means based on the planet size the sorting will be done.

Comparator
1) Comparator is an Interface
2) It is resides into the java.util package
3) It is in the java since java 1.2
4) Its author is Josh Bloch and Neal Gafter.
5) Comparator contains two methods 1) int compare(Object o1, Object o2) 2) boolean equals(Object objt).
6) The compare method compares two objects. It compares the first object with
the second object and based on the comparision it returs negative, zero or positive integer value.
7) It throws ClassCastException if the object
8) One can create multiple comparator based on the required sorting types.

Interface code

package java.util;
public interface Comparator {
int compare(T o1, T o2);
boolean equals(Object obj);
}

Example
import java.util.Comparator;

public class PlanetComparatorByName implements Comparator{

public int compare(Planet p1, Planet p2) {

if(p1.getName()==null && p2.getName()==null) {
return 0;

} else if(p1.getName()==null && p2.getName()!=null) {
return -1;

} else if(p1.getName()!=null && p2.getName()==null) {
return 1;

} else if(p1.getName().length()>p2.getName().length()) {
return 1;

} else if(p1.getName().length() return -1;

} else {
return p1.compareTo(p2);
}

}

}

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;

public class PlanetEngine {
public static void main(String[] args) {
Planet p0 = new Planet("sun",0);
Planet p1 = new Planet("mercury",1);
Planet p2 = new Planet("venus",2);
Planet p3 = new Planet("earth",3);
Planet p4 = new Planet("mars",4);
Planet p5 = new Planet("saturn",5);
Planet p6 = new Planet("jupiter",6);
Planet p7 = new Planet("uranus",7);
Planet p8 = new Planet("neptune",8);
Planet p9 = new Planet("pluto",9);

List list = new ArrayList();
list.add(p0);
list.add(p1);
list.add(p2);
list.add(p3);
list.add(p4);
list.add(p5);
list.add(p6);
list.add(p7);
list.add(p8);
list.add(p9);

System.out.println("\n\nSORGING BYE NAME LENGTH USING COMPARATOR ");
Collections.sort(list, new PlanetComparatorByName());

Struts actions redirect and action chaining

noreply@blogger.com (Raj) — Fri, 11 Dec 2015 11:29:00 +0000

Action redirect jsp code:

 <package name="default" extends="struts-default">  
   <action name="user" class="com.raj.UserAction">  
     <result name="success" type="redirect">REDIRECT_ACTION</result>  
   </action>  
   <action name="saveAction" class="com.raj.SaveAction">  
     <result name="success">/success.jsp</result>  
   </action>  
 </package>

In Action redirect it makes a complete a new call to the new action. so the values in to the stack will be of the new actions. while in the case of the action chaining it will make the call to the new action with the values of the previous action and the values of the new actions. Action Chaining jsp code:

 <package name="default" extends="struts-default">  
   <action name="user" class="com.raj.UserAction">  
     <result name="success" type="chain">CHAIN_ACTION</result>  
   </action>  
   <action name="saveAction" class="com.raj.SaveAction">  
     <result name="success">/success.jsp</result>  
   </action>  
 </package>

How to use projection in Hibernate ?

noreply@blogger.com (Raj) — Fri, 11 Dec 2015 10:32:00 +0000

The projections concept is introduced in hibernate
3.0 and mainly we can do the following two operations using the projection
We can load partial object from the database
We can find the Result of Aggregate functions
Projection is an Interface given in “org.hibernate.criterion” package, Projections is a class
given in same package, actually Projection is an interface, and Projections is a class and is a
factory for producing projection objects.
In Projections class, we have all static methods and each method of this class returns
Projection interface object.
If we want to add a Projection object to Criteria then we need to call a
method setProjection()
Remember : while adding projection object to criteria, it is possible to add one object at a
time. It means if we add 2nd projection object then this 2nd one will overrides the first one
(first one wont be work), so at a time we can have only one projection object to criteria
object.
Using criteria, if we want to load partial object from the database, then we need to create a
projection object for property that is to be loaded from the database

How to use?
Criteria criteria = session.createCriteria(Entity.class);
criteria.setProjection(Projections.property("name"));
List list = criteria.list();
Iterator iterator = list.iterator();
while(iterator.hasNext())
{
String s = (String) iterator.next();
// ---- further code -----
}

If we add multiple projections to criteria then the last projection added will be considered
to execute

Criteria criteria = session.createCriteria(Entity.class);

Projection p1 = Projection.property("id");
Projection p2 = Projection.property("name");
criteria.setProjection(p1):
criteria.setProjection(p2):
List list=crit.list();

Here collectiions list, is going to contain the name in the form of String objects, but Entity id are
over ridden, second projection over rides the first one, i mean p2 only will works p1 will not works,
actually there is a way to add multiple projections to criteria to select more than one column value.

SessionFactory sessionFactoryObj = configurationObj.buildSessionFactory();
Session sessionObj = sessionFactoryObj.openSession();

Criteria criteriaObj = sessionObj.createCriteria(Entity.class);
criteriaObj.addOrder(Order.desc("id"));

ProjectionList projList = Projections.projectionList();
projList.add(Projections.property("id"));
projList.add(Projections.property("category"));
criteriaObj.setProjection(projList);

List entityList = criteriaObj.list();
Iterator iteratorObj = entityList.iterator();
System.out.println("ID \t CATEGORY ");

while(iteratorObj.hasNext()){
Object data[] = (Object[])iteratorObj.next();
System.out.println(data[0]+" \t "+data[1]);
}

How to use criterion in Hibernate ?

noreply@blogger.com (Raj) — Fri, 11 Dec 2015 10:25:00 +0000

Criterion
Criteria criteria = session.createCriteria(Entity.class);
Criterion criterion =Restrictions.gt("id", new Integer(11));
// .gt() : means greater than
// id is a variable of our POJO class Entity.java
criteria.add(criterion); // adding criterion object to criteria class object
List l = criteria.list(); // executing criteria query

In our above example we are fetching the data by comparing id greater than (>) 11
If we want to put more conditions on the data (multiple conditions) then we can use
.and() method ,. or() method , .eq() method using the Restrictions class

Restrictions
Criteria criteria = session.createCriteria(Entity.class);
criteria.add(Restrictions.and(Restrictions.like("name","%M%"),Restrictions.eq("category",ne
w String(“bird”))));
List list = criteria.list();
Iterator it = list.iterator();

Configuration configurationObj = new Configuration();
configurationObj.configure("hibernate.cfg.xml");

SessionFactory sessionFactoryObj = configurationObj.buildSessionFactory();
Session sessionObj = sessionFactoryObj.openSession();

Criteria criteriaObj = sessionObj.createCriteria(Entity.class);
Criterion criterion = Restrictions.gt("id", new Integer(0));
// means : where id > 0

criteriaObj.add(criterion);

criteriaObj.addOrder(Order.desc("id"));
// will fetch the data into descending order
//criteriaObj.addOrder(Order.asc("id"));

// will fetch the data into ascending order
List entityList = criteriaObj.list();
Iterator entityListIterator=entityList.iterator();
System.out.println("ID\t NAME \t CATEGORY");
System.out.println("-------------------------");
while(entityListIterator.hasNext()){
Entity entityObj=(Entity)entityListIterator.next(); System.out.print(entityObj.getId()); System.out.print(" \t"+entityObj.getName()); System.out.println(" \t"+entityObj.getCategory());
}
System.out.println("-------------------------");
sessionObj.close();
sessionFactoryObj.close();

Hibernate + How to add condition in annotation ?

noreply@blogger.com (Raj) — Thu, 10 Dec 2015 11:25:00 +0000

There are two ways to add the condition/where clause into the annotation class
1) at the class level
2) at the field method or field declaration

@Entity
@Table(name = "TBLM_PACKAGE")
@Where(clause = "PACKAGE_MODE!='DESIGN'")
public class PkgData{

private String packageMode;

@Column(name = "PACKAGE_MODE")
public String getPackageMode() {
return packageMode;
}

public void setPackageMode(String packageMode) {
this.packageMode = packageMode;
}

}

Everything about java main(String[] args) method

noreply@blogger.com (Raj) — Tue, 08 Dec 2015 07:45:00 +0000

main method is the first method which get called automatically when the program executes.
there must be only one main in a java program which you want to execute.
in main method signature/prototype
public :
It is a access specifier which defines the scope of the method it must be public

static:
makes the method to be called with the class name as to run the program we use the class name. thats is the reason static is there in main method.

void:
void states that the main method doesnt return anything. and it must be void only.

main : it is a name of method.

(String[] args) : here args is an array of String class and it must be string class array only.
here instead of String[] args you can use varargs i.e String... args

main method cannot be override
main method can be overloaded.

Servlet Life Cycle perfect steps

noreply@blogger.com (Raj) — Sat, 05 Dec 2015 06:00:00 +0000

Servlet Life Cycle

The life cycle of a servlet is controlled by the container in which the servlet has

been deployed. When a request is mapped to a servlet, the container performs the

following steps.

1. If an instance of the servlet does not exist, the web container

a. Loads the servlet class.

b. Creates an instance of the servlet class.

c. Initializes the servlet instance by calling the init method. Initialization

is covered in Initializing a Servlet (page 456).

2. Invokes the service method, passing request and response objects. Service

methods are discussed in Writing Service Methods (page 457).

If the container needs to remove the servlet, it finalizes the servlet by calling the

servlet’s destroy method.

Hibernate HQL Command execution ways

noreply@blogger.com (Raj) — Sat, 05 Dec 2015 05:57:00 +0000

Selecting Complete Object

In this approach, we are going to select complete object from the database, so while iterating the
collection, we need to typecast each object into our POJO class type only

Internally hibernate converts each row selected from the table into an object of POJO class and
hibernate stores all these POJO class objects into list so while iterating the collection, we
typecast into the type of POJO class

Example
Query qry = session.createQuery("--- HQL command ---");
List objList = qry.list();
Iterator iterator = objList.iterator();
while(i iterator.hasNext())
{
Object obj = iterator.next();
Entity entityObj = (Entity)obj;
/* ……. further code ….. */
}

Selecting Partial Object with More than one Column

In this approach we are going to select partial object, (selected columns, i mean more than
one column)

In this case hibernate internally stores the multiple column values of each row into an object
array and stores these object arrays into List collection

At the time of iterating the collection, we need to typecast the result into an object arrays

Example :
Query qry = session.createQuery("select e.id,e.name from Entity e");
List dataList =qry.list();
Iterator iterator = dataList.iterator();
while(iterator.hasNext())
{
Object obj[] = (Object obj[])iterator.next();
System.out.println("-------");
}

Selecting Partial Object with single column

In this case we are going to select partial object with single column from the database

In this case hibernate internally creates an object of that value type and stores all these
objects into the list collection

At the time of iterating the collection, we need to typecast into that object type only
Example
Query qry = session.createQuery("select e.id from Entity e");
List dataList =qry.list();
Iterator iterator = dataList.iterator();
while(iterator.hasNext())
{
Integer id = (Integer)it.next();
System.out.println(id.intValue());
}
