Despite all the complexity and power Swing’s text components provide, it’s still pretty simple to do most things. Figure 19-1 shows each of the six Swing text components, plus an extra JTextArea (to show a different wrapping style) and an extra JEditorPane (to show a different EditorKit).

SimpleAttributeSet attrs = new SimpleAttributeSet( ); StyleConstants.setForeground(attrs, ...
