Usage

From source file:MainClass.java

public void paint(Graphics g) {
    int fontSize = 20;

    g.setFont(new Font("TimesRoman", Font.PLAIN, fontSize));

    FontMetrics fm = g.getFontMetrics();

    String s = "www.java2s.com";

    int stringWidth = fm.stringWidth(s);

    int w = 200;/*from  www.j ava  2 s  . c  om*/
    int h = 200;

    int x = (w - stringWidth) / 2;
    int baseline = fm.getMaxAscent() + (h - (fm.getAscent() + fm.getMaxDecent())) / 2;
    int ascent = fm.getMaxAscent();
    int descent = fm.getMaxDecent();
    int fontHeight = fm.getMaxAscent() + fm.getMaxDecent();

    g.setColor(Color.white);
