多行 JTextField 的问题

Question

I have a JTextField and need to have 3 lines in it, such as these:

HI
MY name
is mehdi

How can I set the text in a JTextField ? I tried \n , but it didn't work.

Answer 1

1: JTextField does not support multiline. what you want is a JTextArea

2: Newlines aren't the same on all systems, you might have to use "\r\n" if you are running Windows. Since Java 7, there is System.LineSeparator to solve this issue.

(see the Oracle documentation )

Answer 2

You can't get multi-line behavior on single-line JTextField,

use JTextArea instead
