Append text in Java’s jtextarea

There is something wrong with my text area

I use jtextarea1 Append ("smart and interesting"); Add text

First attachment:

Then I use jtextarea1 Append ("fight"); Add next text

Second attachment

What I really want is to replace "clever and interesting" with "battle" But I can't do that I tried to use jtextarea1 removeAll(); But it didn't work How to delete "clever and interesting" so that I can add "battle" to the first line

Note: "word hint" is fixed

What can I do?

Solution

If your jtextarea only contains "word hint:...", use the settext () method:

jTextArea1.setText("WORD HINT:\n" + word);

This will replace all text with what you want

BTW: removeall() is a part of the container class. Instead of deleting text, it deletes subcomponents
