import java.awt.RenderingHints;
import java.awt.font.FontRenderContext;
import java.awt.geom.Rectangle2D;
// w w w .j a v a 2 s . c o m
import javax.swing.JComponent;
import javax.swing.JFrame;
class MyCanvas extends JComponent {
public void paint(Graphics g) {
Graphics2D g2 = (Graphics2D) g;
g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
RenderingHints.VALUE_ANTIALIAS_ON);
g2.setFont(new Font("Serif", Font.PLAIN, 48));
FontRenderContext frc = g2.getFontRenderContext();
Rectangle2D bounds = g2.getFont().getStringBounds("java2s.com", frc);
g2.draw(bounds);
}
}
public class Main {
public static void main(String[] a) {
JFrame window = new JFrame();
window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
window.setBounds(30, 30, 450, 450);
window.getContentPane().add(new MyCanvas());
window.setVisible(true);
}
}
