Clear first line jtextarea

Question

How do I clean or remove the first line in a JTextArea?

I have used so far

int start = 0;
                     int end = 131;
                     area.replaceRange (null, start, end);

but it is also obsolete as a method of JTextArea text is dynamic so this is not good.

Answer 1

Use:

int end = textArea.getLineEndOffset(0) 
textArea.replaceRange("", 0, end);
