Re: Jtext area

Use JTextArea methods append(String str) or setText(String str). Nothing big.

You get that exception because you haven't initialized the objects. You have create something with "new" in order to use it.

Re: Jtext area

Basically displaying text on jTextArea is not a difficult thing to do. Maybe there is a minute error to be fixed. Pls post your code so that we can check it!

@bluerose

I think javaAddict conveyed that same point with his post. Please don't repeat people for the sake of posting (unless you're adding something to the discussion), otherwise, you'll become like adatapost.
