Making Up for Missed Classes

2010-07-29T07:38:00.000-07:00

When the store opened almost two weeks ago, I had to miss two (2) of my classes just to attend to stock operations. And, up to this date, business works continue to consume me that my teaching works indeed pile up.

I have to however squeeze in my works and simply prioritize whatever is more urgent and needed. It is quite wiser and important that we pursue security over our works, properties and family just in case unexpected events happen. Thus, it can be wiser for me and everyone else if insurance like health and cheap car insurance can be one of our top priorities.

Because of the missed classes, I have to cope with my absences and that means putting extra hours in school to attend to my students and their subject requirements.

The extended time will be over soon and I can only be more relieved.

Another illustration of exception handling is the use of exception type, ArithmeticException which is normally used for division by zero among other arithmetic operations.

See the program below for this example.

[+/-] show/hide

/* program for try and catch */
import java.lang.*;
import java.io.*;
public class TryDemo2{
public static void main ( String args[]) throws IOException{
BufferedReader stdin = new BufferedReader(new InputStreamReader (System.in));

System.out.println("Input a numerator:");
String numerator=stdin.readLine();
int num1=Integer.parseInt(numerator);
System.out.println("Input a divisor:");
String divisor=stdin.readLine();
try{

int num2=Integer.parseInt(divisor);
System.out.println("The quotient of "+numerator+" and "+divisor+" is "+num1/num2);
}
catch (ArithmeticException ex){

System.out.println("Division by zero! ");
}

}

}

Catch Errors through Exceptions

2010-07-29T07:21:00.000-07:00

Exceptions in Java can come in 3 forms: errors, runtime exceptions and logical exceptions. Errors and logical exceptions should be corrected as these affect the program's reliability and accuracy. However, runtime exceptions like division by zero, wrong input format, array access out of size, and etc. However, Java can handle these exception through try -- catch blocks.

Typically, NumberFormatException is encountered when a non-numeric input is encoded for a number input. This shall cause a program disruption that shows up the stack trace or the causes of disruption and from what method among other information.

The sample program below shows the use of exception.

[+/-] show/hide

/*program for try and catch */
import java.lang.*;
import java.io.*;
public class TryDemo1{
public static void main ( String args[]) throws IOException{
BufferedReader stdin = new BufferedReader(new InputStreamReader (System.in));
String myInput;
System.out.println("Input an integer:");
myInput=stdin.readLine();
try{
int num=Integer.parseInt(myInput);
System.out.println("The square of "+num+" is "+num*num);
}
catch (NumberFormatException ex){
System.out.println("You have encoded a wrong input");
}
System.out.println("Goodbye!");
}

How to Enhance Social Skills in School

2010-07-22T17:16:00.000-07:00

I was never an extrovert person before where I spent most of my schooling days only indoor and academic. However, from prior experience and teaching exposures, you too can develop your social skills. You can employ the following tips to rid gradually your inhibition from social activities.

1. Develop small group of friends who share with you similar interests and values;
2. Be open to welcoming new acquaintances from your friends' circles;
3. Join academic or non - academic groups;
4. Take personality - enhancement talks or fora;
5. Join in social events - start with required activities and extend these to off - school fun; and
6. Enjoy the company of others.
7. Enhance your personality through fashion and body makeover, regular exercise, diet and other personality - boosting measures like apidexin to complement your weight loss/gain programs.

Being alone may mean fun too, however, social skills are imperative whenever you wish to work. Thus, exposure while in school can gradually help you improve your interpersonal skills and through this, your confidence is further boosted. It will simply come handy when you assert your worth as you apply for or pursue a job.

School Acquiantance Day Today

2010-07-22T16:51:00.000-07:00

Classes are suspended for half a day today to give way to our evening Acquaintance Party and the theme is for everyone to wear black and white outfit.

My sister has to scout around for the perfect match although I am quite sure other students have had troubles finding their own suits. I have to however settle with the ones in my closet and simply mix and match them.

I have to just pack my own clothing since store works are still to be attended today until 7pm. I am quite sure students are excited to show off their attire and paint the town red with all the anticipated fun.

Method overriding is also possible in inheritance; with similar method name, a child class can replace the methods in the parent class.

Depending on which method you access, you will see unique actions from the instantiated class. See a sample program of how I have two methods of the same name. And, with a constructor, I pass the initial value to my classes.

How to Protect Yourself from Misfortune

2010-07-20T08:44:00.000-07:00

Irregardless of culture, religion or gender, mishaps or misfortunes for others may happen at the most unexpected time. Thus, it pays off when we are proactive and reactive that we respond to present issues and anticipate future trends.

I get nervous when unexpected things happen and learning how to drive a motorbike at a very late age does not all help. It is however a good thing that I had a good driver to teach me and I took an orientation on traffic rules. Traffic situation is always worse in most parts of the Philippines and along with this is the monstrous number of road accidents.

Normally, a petty delinquent driver is penalized through a fine and traffic reorientation. But, don't you know that in California, when you receive your California Federal Court Traffic Ticket for a violation, you can use a an online traffic school that can help you reclaim your demerit points from traffic misfortunes. The state court recognizes this site and with a payment of $19.95, you can take the lesson and associated exam at your own pacing until you finish the complete set of lessons and you warrant for certification. An 8 - hour of online traffic schooling may be too much for you but their system allows you to cut the lessons to different times as your progress is automatically saved allowing you to resume from where you have last worked on.

At this time where everyone seems in a hurry, it is only sensible that we employ technology to get things done.

The Use of Super in Java Programs

2010-07-20T08:29:00.000-07:00

The Java keyword super has a special use in the application of inheritance. When we pass parameters to our constructors, we also perform the same thing for parents and child classes. A child class may access the parent class' fields through the use of super to pass parameters to parent class.

See the sample below for the illustration.

[+/-] show/hide

/*with super in constructor*/
import javax.swing.*;
public class SampleInheritance4{

public static void main (String args[]){
String myname=JOptionPane.showInputDialog("Input a student name: ");
String myaddress=JOptionPane.showInputDialog("Input a student's address: ");
String mycourse=JOptionPane.showInputDialog("Input a student's college course: ");

College2 obj1=new College2(myname,myaddress);
obj1.setcourse(mycourse);

JOptionPane.showMessageDialog(null,"object of the child class");
JOptionPane.showMessageDialog(null,"Student's Info: "+"\n"+obj1.name+"\n"+obj1.getaddress()+"\n"+obj1.getcourse());

}

}

class Student2{
protected String name;
protected String address;

String getname()
{return this.name;}

String getaddress()
{return this.address;}

}

class College2 extends Student2{

College2(String xname,String xaddress){
super.name=xname; // passing the values of xname and xaddress to parent variables names and address
super.address=xaddress;
}

String course;

void setcourse(String xcourse)
{course=xcourse;}

String getcourse()

How Skills Improve Your Intelligence

2010-07-20T08:15:00.000-07:00

I read from few articles of notable individuals that IQ is inate and can be highly affected by our own genes; however, this does not mean that our skills or competencies are limited if our IQ is less or negligible. Readers' Digest once featured that IQ can be boosted through different means including:

1. getting a sensible and intellectual partner for sensible conversations throughout your time;
2. acquiring new skills as new skills create more neurons that affect our intelligence;
3. reading more and more;
4. getting a challenging job;

At my age, a challenging job seems hard to endure, but, through constant drive and push, our brain can fully work. I recently learned how to drive and this is a new skill that requires wits and a lot of practical sense. Responsibility however, does not end before and during traffic exam; greater responsibility is even endured once we receive our driver's license. Inevitably, however, road accidents or unintentional lapse to abide by the road rules may possibly happen causing infringement against our license. Thus, it is highly important that we take the needed schooling and doing this fast is simply more preferred.

In Nevada Traffic School Online, they can give you a fast and effective way to relieve your driving points from demerits. A mere $19.95 is a meager amount to reclaim your driving merit points. The court recognizes this traffic school entity and you are allowed to have an 8-hour traffic course. Their vivid instructions on how to take the lesson and the quiz are 1-2-3 ways to getting your license' honor again.

More of Inheritance Illustration

2010-07-20T07:50:00.000-07:00

To define clearly the use of inheritance, we apply this to a relationship between a student who has to go through different schooling levels including college.

The program below assigns the Student as the parent class while College as the child class. Through inheritance, the child class can simply call the methods and fields in the parent class by any object that instantiates it.

The program below illustrates this point.

[+/-] show/hide

import javax.swing.*;
public class SampleInheritance3{

public static void main (String args[]){
String myname=JOptionPane.showInputDialog("Input a student name: ");
String myaddress=JOptionPane.showInputDialog("Input a student's address: ");

Student1 obj1=new Student1();
obj1.setname(myname);
obj1.setaddress(myaddress);

How to Improve Your Personality

2010-07-08T06:02:00.000-07:00

Personality affects self - confidence and this is an issue not limited to students or teachers alone. In fact, a number has low self - esteem that printed and non - printed media seem too define personality if you have long legs, great body figures, Hollywood face or hefty paychecks.

However, self - confidence can only be improved through self interventions too to start with. Experts say that to improve your personality, you have to at least address the cause(s) of your poor self - esteem; these can be your physical features like body weights or disfigures or poor hygiene. You can actually remedy this through exercise using fitness equipment or alike. If you have a body disfigure, a surgery or artificial replacement can be done. A poor hygiene that leads to bad breath or body odor can also be remedied as commercial products or services can assist you.

More importantly, it is necessary that you have a positive outlook of yourself; if you believe that you are as important as others and not afraid to commit mistakes, other people will simply respect and trust you more. You don't have to be a celebrity or VIP to be heard; an improved self - confidence can make a valuable difference.

Java's Principle of Inheritance

2010-07-08T05:02:00.000-07:00

One of the highlights of object - oriented programming is its ability to reuse objects. In Java, a parent and child relationship can exist and this is done through the keyword extends.

With the relationship, a child can access the parent's methods and fields with the child's class ability to create its own methods and attributes.

See the program below for the sample program.

import javax.swing.*;
public class SampleInheritance{
public static void main (String args[]){

Anyone But the Teacher Can Be Absent

2010-07-04T16:00:00.000-07:00

Teaching can be a fulfilling work but quite draining too especially if you have more than three (3) subject preparations to do every week. I only have three (3) preparations but two (2) of these subjects are new and with laboratory that quite fill my entire week including Saturdays. I have to exert more readings on these two (2) subjects that I feel I have a full - time load to endure.

I don't feel well as I have colds and my kid has been sick for a couple of days with on and off fever. He has been absent from school for three (3) days and we still have to bring him to his pediatrician for thorough check - up while I am still contemplating whether I have to miss my class. This is the sad thing about being absent when you are teacher; you shall waste the time of all your students and I quite feel quite guilty about that, so, as much as possible, I go to school in spite of uncomfortable situations.

Teaching students about academic contents, health including human growth hormone supplements , social and economic problems, values education among others are complementary. I guess this commitment for service is rooted from my orientation as a private secular teacher.

I only hope I don't get dizzy when I face my students today.

Overcoming College Fear

2010-07-04T05:35:00.000-07:00

It is quite typical among incoming college freshmen that they shall feel anxiety as transition from high school to college kicks in. Thus, most schools do have Freshmen Forum or alike as an intervening medium to aid freshmen adjust with college life.

Normally, they are joined with other freshmen with some experts to discuss openly their anxiety and to discuss how they can cope with the social and academic pressures among others. Further, they are joined with peer councilors and student organizations where they can socially harness their skills, interests and talents.

The role of the Guidance Office contributes significantly to influencing freshmen to like their new life as students. They provide various services to include adjustment from staying away from home, some tips and insights on vices, sex, academic delinquency, health issues including sexual transmitted diseases, beauty and personality tips including blackheads treatment among others.

College life is never easy, however, it provides wide array of experience of fun, wisdom and excitement that when properly enjoyed can make college days quite pleasant and memorable.

Java Certification Exam Tips on Constructors

2010-07-04T05:04:00.000-07:00

Java Certification Exam is given to Java programmers to earn a professional JAVA certified recognition. I found this tips from this Java Exam Tips portal.

The JVM does not call an object’s constructor when an object is cloned.

Constructors never return a value. If you do specify a return value, the JVM will interpret your intended constructor as a method.

If a class contains no constructor declarations, then a default constructor that takes no arguments is supplied. This default constructor invokes the no-args superclass constructor, i.e. calls super();

If, in a constructor, you do not make a direct call to super or this (with or without args) [note: must be on the first line] then super(no args) will first be invoked then any code in the constructor will be executed. See constructors.jpr project.

A call to this in a constructor must also be on the first line. Note: can’t have an explicit call to super followed by a call to this in a constructor - only one direct call to another constructor is allowed.

Term Exams Soon

2010-07-03T17:37:00.000-07:00

Come second week of July, students of my school will have to hurdle through their Prelims exams and this definitely mean paying again for their tuition, complying with term requirements and studying for all their enrolled subjects' exams.

I can only feel for my students who have more than three subjects to juggle with because these subjects shall definitely require them to devote their time and resources. And, when they don't have good study habits, they can quite risk their grades.

I remember when I was still a student, I had to prepare for my major exams a week prior to exam dates to make me more comprehend the subjects and could relax during exam days. I had to endure long hours of deprived sleep, strained eyes from hard readings, and more hours for requirements and due projects that I looked quite lanky and dead. Good thing though that there are now de - stressors and medications like memory boosters and under eye cream for dark circles to make the toil less obvious.

But, nowadays, most students don't seriously study anymore and if they can find a way to make their exams easier, they will simply be happy to oblige to. I just hope that they can do well this coming exam as it entirely affects their semestral grades.

Add-on Works Among Teachers but Unpaid

Bonding with Students

2010-07-03T16:58:00.000-07:00

Few pics with old students and my sibling, Tammy

The thing with teaching in different schools over a span of a decade brings a lot of good and bad sides. For one, I get to meet different eccentric and subtle students and colleagues including administrators. And whenever I can, I try to hang out with them until they are no longer my students and I am out from their school.

I remember joining them in their acquaintance parties, birthdays, proms, weddings, hikings among others and once in awhile, I get to bump with them in malls or in another city but they never fail to say hello and more. So, now that I am in another school, I only hold a lot of good memories with my old students including wacky pictures in my unit that I wish I can slide show together with the rest of the nice pictures with friends and loved ones.

Most of my students are already graduates and working themselves but they still give their greetings through a random message sent to my phone or to my online accounts and I can quite get touched.
