The GraphicsEnvironment class has a couple of handy methods you can use to get the fonts and their names.

Code:

GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
Font[] fonts = ge.getAllFonts();
String[] names = ge.getAvailableFontFamilyNames();

is possible instead of text colors ..... to use colored lines in the choice... Is this possible?
I don't think you could do this in the AWT. I think you could in Swing by making a custom renderer for a JComboBox.
Usually, I would use an array of Colors and fetch the color using the selectedIndex of the Choice.

how i can change the color of a String? I have a String inside a TextArea
TextArea supports only a single color and font. For multiple colors and fonts you will need to use a JTextPane and a StyledDocument.
