我在Java Swing中有一个JTextArea和一个Submit按钮。
需要用换行符将textarea的内容写入文件。

  try {
 BufferedWriter fileOut = new BufferedWriter（new FileWriter（filename.txt））; 
 String myString1 = jTextArea1.getText（）; 
 String myString2 = myString1.replace（\r，\\\
）;

I have one JTextArea and a Submit button in Java Swing.
Need to write the content of textarea into a file with line breaks.
I got the output like, it is written as one string in the file.
try {
    BufferedWriter fileOut = new BufferedWriter(new FileWriter("filename.txt")); 
    String myString1 =jTextArea1.getText();
    String myString2 = myString1.replace("\r", "\n");

    System.out.println(myString2);

    fileOut.write(myString2);
    fileOut.close();
} catch (IOException ioe) {
    ioe.printStackTrace();
}
Please get me some suggestions
解决方案
Why not use JTextArea's built in write function?
JTextArea area = ...
try (BufferedWriter fileOut = new BufferedWriter(new FileWriter(yourFile))) {
    area.write(fileOut);
}
