i m making a text editor in that when ever user type a certain java keyword like void just that word will be appeared as blue and rest other work should be red
i m using keylistener but unfortunately my logic is notworking here
what is happening here is when i write some thing like
class void then i press enter then the color of the text changes to red and from then on the entire text is written in red color
same is the case with blue ....so please can you tell me where i m wrong and what is key thing in this which i m missing ?



The Only way to learn is ...........do!

Check out javax.swing.text.Highlighter. In short:
- retrieve the text field's current highlighter.
- if there is none (null is returned) create one (DefaultHighlighter) and set it.
- get a Highlighter.HighlightPainter (usually DefaultHighlighter.DefaultHighlightPainter).
- add a highligh to the Highlighter.
