Appending text in Java's JTextArea

I have a problem with my text area.

I use jTextArea1.append("cleverly amusing"); to add the text..

FIRST APPEND:

then I use jTextArea1.append("a fight"); to add the next text.

SECOND APPEND

enter image description here

What I Really want is to replace the "cleverly amusing" to "a fight". But I cannot do it. I tried to use the jTextArea1.removeAll(); but there's no effect. How can I remove the "cleverly amusing" so that I can append the "a fight" to the first line.

NOTE: "WORD HINT" is fixed...

What can I do?

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.

Why not use setText(String text) instead of append(String text)?
