THIS IS MY CAR ANIMATION IN JAVA WHICH HAS BEEN CONSTRUCTED BY USING APPLETS CONCEPTS TO RUN THIS PROGRAM LIKE A NORMAL APPLET PROGRAM

import java.awt.*;

import java.util.*;

import java.applet.*;

/* <APPLET CODE="ani.class" WIDTH=400 HEIGHT=300></APPLET>*/

//The basic applet class.The applet shows 4 cars crossing each other at a square.

public class ani extends Applet implements Runnable

{

 Thread t;

 //4 variables used to vary the car's positions.

 int x1=0,x2=380,y1=50,y2=250;

 public void start()

 {

  if(t==null)

  {

   t=new Thread(this,"New Thread");//New side Thread created on start of applet.

   t.start();

  }

 }

 public void stop()

 {

  if(t!=null)

  {

   t=null;//On stop of applet the created thread is destroyed.

  }

 }

 //Implementation of method run() of Runnable interface.

 public void run()

 {

  Thread t1=Thread.currentThread();

  while(t==t1)

  {

   repaint();

   try

   {

    Thread.sleep(100);

   }

   catch(Exception e)

   {   }

  }

 }

 public void paint(Graphics g)

 {

  setBackground(Color.cyan);

  g.setColor(Color.BLACK);

  x1=(x1+16)%400;

  x2=x2-16;

  y1=(y1+12)%300;

  y2=y2-12;

  if(y2<0)

   y2=288;

  if(x2<0)

   x2=384;

  //Draw the roads using 2 filled rectangles using black color.

  g.fillRect(0,130,400,40);

  g.fillRect(180,0,40,305);

  //Draw the white colored lines.

  g.setColor(Color.white);

  for(int i=0;i<20;i++)

  {

   if(i!=9 && i!=10)

    g.drawLine(i*20,150,i*20+10,150);

  }

  for(int j=0;j<15;j++)

  {

   if(j!=7 && j!=8)

    g.drawLine(200,j*20,200,j*20+10);

  }

  //Draw 4 colored cars using filled round rectangles.

  g.setColor(Color.red);

  g.fillRoundRect(x2,152,20,8,2,2);

  g.fillRoundRect(x1,140,20,8,2,2);

  g.fillRoundRect(190,y1,8,20,2,2);

  g.fillRoundRect(202,y2,8,20,2,2);

 }

}

Output:-

The output on applet fame it will display a four way junction one each road one car will be running


 program-2

THIS IS MY SIMPLE CAR WAS DESIGNED TO ILLUSTRATE THE CONCEPT OF THE SWING IMPLEMENTATION FOR APPLET

IT IS SO SIMPLE JUST FIRST YOU DRAW A RECTANGLE AND ATTACH 4 CORNERS S 4 CIRCLES FILL WITH ALL THESE 5 COMPONENTS WITH U R DESIRED COLORS IT IS NOT DESIGNED BY USING THREAD WHICH WILL GIVE U ANIMATION AFFECT

import java.awt.Color;

import java.awt.Graphics;

import javax.swing.*;

public class test extends JApplet {

public static void main(String[] args) {

JFrame frame = new JFrame();

frame.getContentPane().add(new test());

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

frame.setSize(1200,600);

frame.setVisible(true);

}

public void paint(Graphics g) {

try {

int j = 0;

while (j < 1500) {

g.setColor(Color.blue);

g.fillRect(0, 0, 5000, 5000);

g.setColor(Color.yellow);

g.fillRect(250 + j, 250, 100, 50);

g.setColor(Color.red);

g.fillOval(260 + j, 300, 20, 20);

g.fillOval(320 + j, 300, 20, 20);

j++;

Thread.sleep(2);

}

} catch (InterruptedException e) {

}}}

Running of the above code

Run this application like a simple core java program a car shape will move on the screen from left to right only once
