S.N.	Constructor & Description
1	protected Ellipse2D() This is an abstract class that cannot be instantiated directly.

Class methods

S.N.	Method & Description
1	boolean contains(double x, double y) Tests if the specified coordinates are inside the boundary of the Shape.
2	boolean contains(double x, double y, double w, double h) Tests if the interior of the Shape entirely contains the specified rectangular area.
3	boolean equals(Object obj) Determines whether or not the specified Object is equal to this Ellipse2D.
4	PathIterator getPathIterator(AffineTransform at) Returns an iteration object that defines the boundary of this Ellipse2D.
5	int hashCode() Returns the hashcode for this Ellipse2D.
6	boolean intersects(double x, double y, double w, double h) Tests if the interior of the Shape intersects the interior of a specified rectangular area.

Ellipse2D Example

Create the following java program using any editor of your choice in say D:/ > AWT > com > tutorialspoint > gui >

AWTGraphicsDemo.java

package com.tutorialspoint.gui;

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

public class AWTGraphicsDemo extends Frame {
       
   public AWTGraphicsDemo(){
      super("Java AWT Examples");
      prepareGUI();
   }

   public static void main(String[] args){
      AWTGraphicsDemo  awtGraphicsDemo = new AWTGraphicsDemo();  
      awtGraphicsDemo.setVisible(true);
   }

   private void prepareGUI(){
      setSize(400,400);
      addWindowListener(new WindowAdapter() {
         public void windowClosing(WindowEvent windowEvent){
            System.exit(0);
         }        
      }); 
   }    

   @Override
   public void paint(Graphics g) {
      Ellipse2D shape = new Ellipse2D.Float();
      shape.setFrame(100, 150, 200,100);
      Graphics2D g2 = (Graphics2D) g; 
      g2.draw (shape);
      Font font = new Font("Serif", Font.PLAIN, 24);
      g2.setFont(font);
      g.drawString("Welcome to TutorialsPoint", 50, 70);
      g2.drawString("Ellipse2D.Oval", 100, 120); 
   }
}

Compile the program using command prompt. Go to D:/ > AWT and type the following command.

D:\AWT>javac com\tutorialspoint\gui\AWTGraphicsDemo.java

If no error comes that means compilation is successful. Run the program using following command.

D:\AWT>java com.tutorialspoint.gui.AWTGraphicsDemo
