I have a problem with my text area.
I use jTextArea1.append(\"cleverly amusing\"); to add the text.. 
FIRST APPEND:
        
Why not use setText(String text) instead of append(String text)?
Instead of removeAll, just call setText() with the first line you want and then you can append the additional data if you want.
If your JTextArea will only contain "WORD HINT: ..." then use the setText() method:
jTextArea1.setText("WORD HINT:\n" + word);
This will replace all the text with what you want.
BTW : removeAll() is part of the Container class, and is not to remove text but child components.
