jTextArea problem

zhoujjjj

Excuse me, can the jTextArea class delete a row of data.
For example, the data inside
132
231
125
134
321
How can I delete the line "134"?
Thanks for a piece of code. anxious

If jTextArea is editable, delete it manually

That said upstairs. It seems that I have not seen an example of deleting a specific line in a textarea, and the list is almost the same...

By the way, if you just want to implement this function, you can clear the textarea first, then create a new string, delete that line in the string, and then settext() in the textarea.

If you need to update such a string of String in real time, I think it would be more appropriate to use JList.
You can store the data in a List, and then let JList update the content in the List in real time. You only need to add or delete data from the List.

Agree, JList is generally used for striped display, textarea is generally used to display a large section of string with little change in content
