JFrame的JTextArea无法保存长粘贴的文本

Question

I am making a JTextArea so users can paste long amounts of text into it. However, when that happens, it causes the second image below to occur. Can anyone help?

Answer 1

1. Wrap the JTextArea in a JScrollPane

    JTextArea textArea = new JTextArea(25, 60); JScrolPane scroll = new JScrollPane(textArea); frame.add(scroll); 

2. Set the line wrap and the wrap style word to true

    textArea.setLineWrap(true); textArea.setWrapStyleWord(true);
