How to create Animation

     

This section illustrates you how to create Animation. We are proving you an example defining a static variable DELAY of integer type. The object of Insets class is provides the representation of the borders i.e. left, right, top, bottom. the object of Timer class act as a thread which executes all the timer's tasks, sequentially.

 The TimerTask class performs a task which can be scheduled for one-time or repeated execution by a Timer class. The method  timer.schedule(timerTask, 0, DELAY) schedules the specified task for repeated fixed-delay execution.

The class Color defines an array of colors. The method fillRect() fills the rectangle with the colors showing animation.

Here is the code of CreateAnimation.java

import java.awt.*; import java.util.Timer; import java.util.TimerTask; import javax.swing.JFrame; public class CreateAnimation extends JFrame { private static int DELAY = 90; Insets insets;   Color colors[] = { Color.PINK, Color.YELLOW, Color.GREEN, Color.RED,   Color.BLUE, Color.CYAN };   public void paint(Graphics graphics) {   super.paint(graphics);   if (insets == null) {   insets = getInsets();   }   int steps=colors.length;   int x = insets.left;   int y = insets.top;   int width = getWidth() - insets.left - insets.right;   int height = getHeight() - insets.top - insets.bottom;      synchronized (colors) {   for (int i = 0; i < steps; i++) {   graphics.setColor(colors[i]);   graphics.fillRect(x, y, width, height);   }   }   }   public void go() {   TimerTask timerTask = new TimerTask() {   public void run() {   Color color = colors[0];   synchronized (colors) {   System.arraycopy(colors, 1, colors, 0, colors.length - 1);   colors[colors.length - 1] = color;   }   repaint();   }   };   Timer timer = new Timer();   timer.schedule(timerTask, 0, DELAY);   }  public static void main(String args[]) {   CreateAnimation animation = new CreateAnimation();   animation.setSize(250, 200);   animation.show();   animation.go();   } }
