A few simple steps to profile J2ME applications on your Mac

noreply@blogger.com (Anonymous) — Thu, 9 Dec 2010 21:57:00 +0800

The first step of optimizing any application is finding out that small percentage that is taking up your applications execution time. That is why profiling tools are invaluable to find where to squeeze out more juice. Specially when it comes to J2ME applications where resources are very limited.

Here is a simple guide on setting up your J2ME applications for profiling. We are going to make use of the Built in profiler of Java ME SDK 3.0 for Mac, a very useful tool to be able to pin point the areas that need optimization....

Lets start by setting up our existing J2ME project on the Java ME SDK for Mac IDE.

Open up your JavaME SDK IDE and create a new project.

Now that our project is setup.... we set the profiler on.....

If we did everything right... we the profile data from our application will be opened on our IDE

Now we can analyze the data that the profiler gathered and we can now plan our optimization....

Quick and simple guide on developing J2ME apps on your Mac

noreply@blogger.com (Anonymous) — Thu, 9 Dec 2010 00:15:00 +0800

Planning to develop J2ME applications?? Well here is a quick and easy guide that will get you started in no time.

What you will need....

a Mac computer... Oh you want to develop on PC? Ask me how :P

an IDE.... you have lots of choices.... personally i prefer Eclipse IDE in the case of J2ME you're better off getting Pulsar Eclipse Mobile Platform you could also use Netbeans IDE or you can use Java ME SDK 3.0 for Mac you have lots of choices, i use all of them well not at the same time i code in Netbeans and Eclipse and i just use the Java Me SDK for profiling mobile apps.

Now that you have your IDE you will also need the Java Dev Kit and Java ME SDK 3.0 for Mac (Sa wakas meron na rin sa mac hehehe).

Requirements list:
1.) Mac computer (you can use PC its almost the same setup).
2.) IDE - Pulsar Eclipse Mobile Platform or Netbeans IDE or just use the Java ME SDK 3.0 for Mac.

3.) Software Dev Kits - Java Dev Kit and Java ME SDK 3.0 for Mac

Are you ready? Here we go....

First we fire up our IDE.... I will be using Java ME SDK 3.0 for Mac for the purpose of this tutorial....

Then we create a new project.....

Choose MIDP applicaton....

Choose you project name and location...

Choose an emulator.... in this case i use default.... click Finish....

Our new project shows up on our project explorer, and our class opens up on our editor window....

We change some code on our sample Midlet class....

Now we run our project.... The emulator displays our text.....

Now, there you have it.... a few simple steps to get you started on your J2ME application.

Introduction to Java Swing Applications

noreply@blogger.com (Anonymous) — Mon, 4 Oct 2010 02:31:00 +0800

Here is my next tutorial for new JAVA developers, I would like to introduce to you JAVA swing applications. JAVA swing is a GUI(Graphical User Interfame) framework for JAVA and it is included in the JDK(JAVA Development Kit). If you really want to make complex user interface using JAVA Swing , Netbeans IDE has a very good Interface Designer, but i wont be using Netbeans for my tutorial because the purpose of this tutorial is just to introduce you to Swing development. Instead we will be using my favorite IDE which is Eclipse like my past JAVA tutorials.

To start with our tutorial we will need to create a new JAVA Project in Eclipse. If you still do not know to do this you better start here..

We will now create our new Java Swing Class

Right click on your src folder and choose New... then choose Class

then choose your Class Name and Package name. In our case use

Package -> com.wfdb

Class Name -> HelloSwing

then click on Finish...

Our new class should look something like this...

Now we add some code...

First we extend our HelloSwing Class to Jframe Class

public class HelloSwing extends JFrame {

Then we add a constructor for our HelloSwing Class

public HelloSwing() {

}

The constructor of a class is called when we make an instance of that class executing the code inside it

Now we add code inside our constructor

public HelloSwing() {

JLabel hello = new JLabel("Hello World");

add(hello);

setSize(100, 100);

setVisible(true);

}

Lets discuss what each line of code does...

1.) JLabel hello = new JLabel("Hello World"); - this piece of code means that we create a new Instance of a JLabel Class set its value to "Hello World" and store it in our hello object.

JLabel is a class in the swing framework just like JFrame. There are other classes we can use like JTextField, JButton, etc. that we can use for our JAVA application.

2.) add(hello); - this piece of code adds our hello object to our HelloSwing Class. the method add(); is a method from the JFrame class, because we extended our HelloSwing Class to JFrame we are able to use its public methods.

3.) setSize(100, 100); - this piece of code sets the size of our Frame to 100 width and 100 height. It is also a method of the JFrame Class which we have extended for our HelloSwing Class.

4.) setVisible(true); - this is also a method of the JFrame Class and it sets our Frame visible.

Next is we add the entry point of our JAVA application...

public static void main(String[] args) {

new HelloSwing();

}

1.) public static void main(String[] args) { } - This is the entry point of a JAVA application it is the first method that will be executed

2.) new HelloSwing(); - Inside our main method we create an instance of our HelloSwing Class. using the new keyword we create an instance of a Class.

Our code should look something like this...

Now to run our code...

We right click on our Class... then choose Run As... and choose Java Application

Our result should look something like this...

There you have it... your first JAVA swing application..... Hope you enjoy another one of my tutorials...

if you have any questions or suggestions don't be shy to comment or email me.... :D

Quick and Easy JAVA Applet Tutorial

noreply@blogger.com (Anonymous) — Sun, 3 Oct 2010 02:14:00 +0800

Want to get started on developing JAVA applets? These few quick and easy steps can help you get going in no time.

If you are still not familiar on developing JAVA applications. Click here to get you started on JAVA.

In this tutorial we will be making use of the Eclipse IDE(Integrated Development Environment). If you do not know eclipse yet start with this tutorial here.

First step in making a JAVA Applet is to make a new JAVA project in your Eclipse IDE.

Click on File... then select New... then click on Java Project....

Choose a Project Name and click Finish...

Now you have your project... we can start coding... :D

Right click on the src folder and choose New... then choose Class

then choose your Class Name and Package name. In our case use

Package -> com.wfdb

Class Name -> HelloApplet

then click on Finish...

Our new Class file will now look something like this...

Now its time to code our Java Applet

First we have to extend our HelloApplet Class by adding

     public class HelloApplet extends Applet {

This means we are extending the functionalities of the Applet Class to our HelloApplet Class

Next we add some functionality to our applet...

We add a simple paint method which overrides the method from the Applet Class and use it to draw a String

   public void paint(Graphics g) {

   g.drawString("Hello World", 25, 25);

   }

g.drawString("Your Text Here", x, y); <-- This method paints a Text on x and y coordinates

Next is we add the imports at the top of our HelloApplet Class

   import java.applet.Applet;

   import java.awt.Graphics;

Our code should now look something similar to this

Now to run our code...

Right click on our HelloApplet.java Class file from our Project choose Run As... and choose Java Applet...

We should now see a small window pop up and display out Text...

There you have it....

You made your first Java Applet...

Keep on checking my blog for new Java Applet Tutorials.... :D

How To Be a Java Programmer

noreply@blogger.com (Anonymous) — Sat, 2 Oct 2010 18:49:00 +0800

Do you want to be a Java Programmer? Then first you have to be equipped with the tools nessesary for java programming. First thing you will need is a computer (Duh!) , the JDK (JAVA Development Kit), and a good old IDE (Integrated Development Environment)

Programming in java, you could use any of your favorite notepad editor and hack away your code, but in my experience that would be a very long error prone process. So if you want to be a professional Java programmer you will have to choose your tools wisely. My favorite IDE (Integrated Development Environment) for java would be the Eclipse IDE for Java.

There are a lot of Java IDE's out there, but i will list only 3 of the most famous ones:

Intellij IDEA - i have not used it but it is very famous and widely used. You can get it here
Netbeans IDE – another very good IDE, with very good UI designer. I like using it but my favorite is Eclipse. The best thing about them is they are both free. You can get it here
Eclipse IDE – a customizable and portable IDE, just unpack it to any folder and you are ready to go. get it here

Well, before we delve into the mysterious world of java, I would like to introduce it to you with a simple “Hello World” tutorial. For this tutorial we will be using my favorite IDE Eclipse.

First Step is to setup our JDK and our IDE.

Download and install the JDK from here.

also, download the Eclipse IDE and unpack it to the folder of your choice.

Running Eclipse for the first time it will ask you to choose a workplace. Once Eclipse is running First thing we have to do is click make a new project.

Click on File... then select New... then click on Java Project....

Choose a Project Name and click Finish...

Now you have your project... we can start coding... :D

Right click on the src folder and choose New... then choose Class

then choose your Class Name and Package name. In our case use

Package -> com.wfdb

Class Name -> HelloWorld

then click on Finish...

Our new Class file will now look something like this...

Now we add code to our Class...

<code>

public static void main(String[] args){

System.out.println("Hello World!!!");

}

</code>

public static void main(String[] args) {

// your code here

}

this piece of code tells java that our program will start executing from this part of the code...

System.out.println("Your Text Here");

this piece of code tells java to print a piece of string out to our console...

Now we run the code...

Right click on our HelloWorld.java class file from our project and click on Run As... And choose Java Application...

Our result should look like this....

Now, there you have it. Your very first Java Program....

Welcome to the wonderful world of java...

More advanced tutotials soon to come... :D

Facebook Backyard Monsters Game Tips and Review

noreply@blogger.com (Anonymous) — Sat, 2 Oct 2010 01:04:00 +0800

Another addicting casual game for facebook involving cute monsters and base defense.

While Browsing the internet, and reading facebook comments and updates i noticed an AD for a facebook game with a cute little green monster. I got curious and said to myself... What the heck try it out... I might get some idea for a game i am trying to make.

First you will need to set up your base. The game has nice tutorials as you go along doing quests and building your base while getting rewards for doing so. Starting out you will have a 13 days protection from being attacked by others players which gives you ample time to setup your base and get ready to attacking other players.

Using your 13 days protection to become a monster base

First step is to get as much workers for your initial shinys from the game. You will have to wait until you get a store, then use up as much shiny you have to buy workers. Workers will be able to help you build your base, the more workers you have the more you can use to build simultaneously. Next Step is to get as much resources and storage as fast as posible. What is the use of workers without resources to build? Because you are protected for 13 days, you should concentrate on upgrading your resuorces and storage, you need not worry about other players attacking except for some wild monsters which a few sniper towers can handle. So build up your resources and always upgrade your Town Hall because you will have more resources. Getting to the end of your protection status you will have maxed Town Hall and a lot of resources to back you up in you hunt to destroy other players bases.

Backyard Monsters is another addicting Facebook game. It is fun and has nice graphics with cute monsters. I recommend it to casual gamers who like playing strategy and tower defence games. And the best part is its free like all of facebook games. ENJOY!! :D
