Graphics Class
- In Java, the drawing takes place via a Graphics object, this is an instance of the java.awt.Graphics class.
- Each Graphics object has its own coordinate system and all the methods of Graphics including those for drawing Strings, lines, rectangles, circles, polygons and etc.
- We can get access to the Graphics object through the paint(Graphics g) method.
- We can use the drawRoundRect() method that accepts x-coordinate, y-coordinate, width, height, arcWidth, and arc height to draw a rounded rectangle.
Example
import java.awt.*; import java.awt.event.*; import javax.swing.*; public class RoundedRectangleTest extends JFrame { public RoundedRectangleTest() { setTitle("RoundedRectangle Test"); setSize(350, 275); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setLocationRelativeTo(null); setVisible(true); } public void paint(Graphics g) { Graphics2D g2d = (Graphics2D) g; g2d.drawRoundRect(10, 50, 150, 150, 50, 30); // to draw a rounded rectangle. } public static void main(String []args) { new RoundedRectangleTest(); } }
