当多行作为JTextarea的输入时，如何在文件中写入多行？

Question

I take multiple lines as a input from a JTextarea, If I write it in a file, then I get that the multiple lines are write in a one line in file

Examples:

In JTextArea:

I
am
a
student

Means: variable.text="I'\\n'am'\\n'a'\\n'student"; When I write the string s in file I get:

I am a student

But I want that the file will contain the same things as I give as a input means--->

I
am
a
student

This is the code of writing a file :

      BufferedWriter out = new BufferedWriter(
       new OutputStreamWriter(
                  new FileOutputStream(file), "UTF16"));
      int size=1;
      for(Tableclass variable:tablevector)
      {
            out.write(variable.Text); 
            out.newLine();
            size++;

      }
      out.close();

Answer 1

Slighty better version would be :

    try {
        PrintWriter fstream = new PrintWriter(new FileWriter("log.txt"));
    } catch (IOException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }


 for(String word : jTextAreaName.getText().split("\n"))  {    
    fstream.println(word); 
} 
     fstream.flush();

Answer 2

Use out.newLine();

   BufferedWriter out = new BufferedWriter( 
   new OutputStreamWriter( 
              new FileOutputStream(file), "UTF16")); 
  int size=1; 
  for(Tableclass variable:tablevector) 
  { 
        out.write(variable.Text); 
        out.newLine();          
        size++; 

  } 
  out.close(); 

Answer 3

在你的字符串char（10）或char（13）中找到这个字符

int index = textarea.firstIndexOf(CHAR(10));
