AWT Ellipse2D Class
Introduction
The Ellipse2D class states an ellipse that is defined by a framing rectangle.
Class declaration
Following is the declaration for java.awt.geom.Ellipse2D class:
public abstract class Ellipse2D extends RectangularShape
Class constructors
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. |
Methods inherited
This class inherits methods from the following classes:
java.lang.Object
Ellipse2D Example
Create the following java program using any editor of your choice in say D:/ > AWT > com > tutorialspoint > gui >
AWTGraphicsDemo.javapackage 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
