g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
String s = "java2s.com";
Font font = new Font("Courier", Font.PLAIN, 40);
g2d.translate(20, 200);
FontRenderContext frc = g2d.getFontRenderContext();
GlyphVector gv = font.createGlyphVector(frc, s);
int length = gv.getNumGlyphs();
System.out.println(length);
g2d.draw(gv.getOutline());
}
}
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);
