Practical-3 Built an applet that displays a horizontal rectangle in its center. Let the rectangle fill with color from left to right.

 

import java.applet.*;

import java.awt.*;

public class Practical3 extends Applet {

public void paint(Graphics g)

{

    int width=10, height=50;

    g.drawRect(30, 70, 240, 50);

    g.setColor(Color.red);

    for (int i=1;i<25;i++)

    {

        try

        {

        Thread.sleep(1000);

        }

        catch(InterruptedException e)

        {

            System.out.println("Exception generated");

        }

        g.fillRect(30, 70, width, height);

        width=width+10;

    }

}

}

Output:
