如何使Java GUI settext识别二维数组输入的新行

Question

I have a char[xSize][ySize] being sent to my GUI. 我有一个char [xSize] [ySize]发送到我的GUI。 The GUI prints the long string as one long line without recognizing the new lines in it. GUI将长字符串打印为一条长行，而不会识别其中的新行。 What method or code could I use? 我可以使用什么方法或代码？ The code I currently use is: 我当前使用的代码是：

            JFrame frame1 = new JFrame("Start Screen");
            JLabel label = new JLabel();
            frame1.setVisible(true);
            frame1.setSize(500, 500);
            frame1.setLayout(new BorderLayout());
            frame1.add(label, BorderLayout.NORTH);

            //Code to recieve from other program:

            DatagramPacket receivePacket = new DatagramPacket(receiveData, receiveData.length);
            String Sentence = new String(receivePacket.getData());  

            //Print received text to GUI:
            label.setText(Sentence);

Thanks in advance 提前致谢

For something JLabel , you would need to first replace the new lines ( \\n ) with <br> and wrap the text in <html>...</html> 对于JLabel ，您需要先用<br>替换新行（ \\n ），然后将文本包装在<html>...</html>

String Sentence = new String(receivePacket.getData());  

//Print received text to GUI:
label.setText("<html>" + Sentence.replaceAll("\n", "<br>") + "</html>");

Or you might be able to use a non-editable JTextArea instead... 或者，您也可以改为使用不可编辑的JTextArea ...
