Question

Suppose I have a String, “Hello World”. I want to change the style of this string to a BOLD font, and set the size of all the characters from 12 to 18 [pt]. After that I want to use this string in a JLabel and JButton. How can I do that?

Look here http://docs.oracle.com/javase/6/docs/api/java/awt/Font.html#deriveFont%28float%29

JComponent has a setFont() method. You will control the font there, not on the String.

Such as

JButton b = new JButton();
b.setFont(b.getFont().deriveFont(18.0f));
