Since Java 7, there is System.LineSeparator to solve this issue. (see the Oracle documentation) 回答2: You can't get multi-line behavior on single-line

问题 I'm working on this multiplayer game for school and I'm currently trying to take a username from a JTextField. Here's the code in question: JTextField textField = new JTextField(); new Statistics(textField.getText()); Statistics takes a string, but when I try this, eclipse is telling me that I need to cast the JTextField as a final.
