Simple Gradient Paint Example

     

This section illustrates you how to use Gradient Paint.

A gradient refers to a colored strip with two defined endpoints. Both the end points are defined with different color. Then the colors will starts changes gradually  from one to the other along a straight line between the two points.

To use a Gradient paint, we have used the class Elipse2D which provides the shape oval. The class GradientPaint allows you to set up a gradient filled shape with a linear color gradient pattern.

Here is the code of SimpleGradientPaintExample.java

import java.awt.*;
import javax.swing.*;
import java.awt.geom.*;
import java.awt.event.*;

public class SimpleGradientPaintExample extends JPanel {
  public void init() {
  setBackground(Color.gray);
  }
  public void paint(Graphics graphics) {
  Graphics2D g2d = (Graphics2D) graphics;
  g2d.setPaint(new GradientPaint(00, Color.cyan, 200,
  200, Color.red, false));
  Ellipse2D.Double ellipse = new Ellipse2D.Double(5,5,200,200);
  g2d.fill(ellipse);
  }
  public static void main(String args[]) {
  JFrame frame = new JFrame("Simple Gradient Paint");
  SimpleGradientPaintExample gradientExample = new
   
SimpleGradientPaintExample();
  frame.getContentPane().add("Center",gradientExample);
  gradientExample.init();
  frame.setSize(new Dimension(300250));
  frame.show();
  }
}
