Usage

From source file:Main.java

public void paint(Graphics g) {

    int fontSize = 20;

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

    FontMetrics fm = g.getFontMetrics();

    int stringWidth = fm.stringWidth(s);

    int w = 200;/*w w  w . j  a  v a  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();
