Animation With Java

Hi guys.. How are you ? Did you read my article about how to make a graphic2D in java ? 

How is it ? It's amazing , isn't t ? hehehe :D

Now we will study about how to make an animation with java. Let's we start it....

package animasiq;

import java.awt.Color;

import java.awt.Dimension;

import java.awt.Font;

import java.awt.Graphics;

public class Animasi extends JPanel {

ball = new Ball(0, 450);

alir=new Player1(-100, 350);

alir.nextX=390-alir.getwidth();

Thread t = new Thread(new Runnable() {

public void run() {

while(true) {

alir.update();

ball.update();

ball.nextX = alir.x + alir.getwidth() +5 ;

if(ball.nextY<=460) ball.nextY+=2; else ball.nextY-=2;

repaint();

try {

if(ball.x>=430){

Thread.sleep(400);

}else{

Thread.sleep(200);

}

} catch (InterruptedException ex) {}

}

}

});

t.start();

}
