Write a program on Filling Rectangles ?
The drawRect() method draws an open rectangle, a box if you prefer. If you need to draw a filled rectangle, use the fillRect() method. Or else the syntax is identical. This program draws a filled square in the center of the applet. This needs you to separate the applet width and height from the rectangle width and height. Here's the code:import java.applet.*; import java.awt.*;
public class FillAndCenter extends Applet {
public void paint(Graphics g) {
int appletHeight = this.getSize().height; int appletWidth = this.getSize().width; int rectHeight = appletHeight/3; int rectWidth = appletWidth/3; int rectTop = (appletHeight - rectHeight)/2; int rectLeft = (appletWidth - rectWidth)/2; g.fillRect(rectLeft, rectTop, rectWidth-1, rectHeight-1); }
}
