Writing JTextArea content into file
提问by SK0004
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.
我在 Java Swing 中有一个 JTextArea 和一个提交按钮。需要将textarea的内容写入带换行符的文件中。我得到了这样的输出，它被写成文件中的一个字符串。
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
请给我一些建议

Replace all \r and \n with:
将所有 \r 和 \n 替换为：
System.getProperty("line.separator")
This will make your code platform-independent and will write new lines to the files where necessary.
这将使您的代码独立于平台，并在必要时将新行写入文件。
Edit: since you use BufferedWriter, you could also use the newLine() method
编辑：由于您使用 BufferedWriter，您还可以使用newLine() 方法

Why did you replace \rby \n?
你为什么换成\r了\n？
The line separator should be "\r\n".
行分隔符应该是"\r\n".

This is what i thought up of :
这是我想到的：
public void actionPerformed(ActionEvent event) {
BufferedWriter writer;
try {
writer = new BufferedWriter(new FileWriter("SimpleText.txt",
false));
text.write(writer);
writer.close();
JOptionPane.showMessageDialog(null, "File has been saved","File Saved",JOptionPane.INFORMATION_MESSAGE);
// true for rewrite, false for override
} catch (IOException e) {
JOptionPane.showMessageDialog(null, "Error Occured");
e.printStackTrace();
}
}
Hope this helps
希望这可以帮助
