Java paint graphics text

How to draw text using GUI in Java

Following example demonstrates how to draw text drawString(), setFont() methods of Graphics class.

import java.awt.Font; import java.awt.Graphics; import java.awt.Graphics2D; import java.awt.RenderingHints; import javax.swing.JFrame; import javax.swing.JPanel; public class Main extends JPanel < public void paint(Graphics g) < Graphics2D g2 = (Graphics2D)g; g2.setRenderingHint( RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON); Font font = new Font("Serif", Font.PLAIN, 96); g2.setFont(font); g2.drawString("Text", 40, 120); >public static void main(String[] args) < JFrame f = new JFrame(); f.getContentPane().add(new Main()); f.setSize(300, 200); f.setVisible(true); >>

Result

The above code sample will produce the following result.

Text is displayed in a frame.
