How to display different shapes using GUI in Java

Problem Description

How to display different shapes using GUI?

Solution

Following example demonstrates how to display different shapes using Arc2D, Ellipse2D, Rectangle2D, RoundRectangle2D classes.

import java.awt.Shape;
import java.awt.geom.*;

public class Main {
   public static void main(String[] args) {
      int x1 = 1, x2 = 2, w = 3, h = 4, 
      x = 5, y = 6, 
	   y1 = 1, y2 = 2, start = 3;
      
      Shape line = new Line2D.Float(x1, y1, x2, y2);
      Shape arc = new Arc2D.Float(x, y, w, h, start, 1, 1);
      Shape oval = new Ellipse2D.Float(x, y, w, h);
      Shape rectangle = new Rectangle2D.Float(x, y, w, h);
      Shape roundRectangle = new RoundRectangle2D.Float (x, y, w, h, 1, 2);
      System.out.println("Different shapes are created:");
   }
}

Result

The above code sample will produce the following result.

Different shapes are created.
