Line breaks in java

Question

Hi, I'm a little new to Java. I am trying to make a line break that is not in a textbox. So far, to make something similar to a line break, I played with the size of the applet on the HTML file. However, it's not working for one of my applets because it must be in several lines.
I know that you can use /n or /r/n for line breaks in a TextArea, but I need to use line breaks to separate Buttons and several TextFields.
In an earlier forum there was something like this:
System.getProperty("line.separator");
I don't really know how to add the line separator to my code. I pasted that just inside
public class ClassName extends java.applet.Applet
implements ActionListener
right before
public void init( )
I tried putting "line.separator" in a string, but it did not work
I also tried the following:
add(/n);
add(/r/n);
add(line.separator);
but none of them worked.
If someone could help me, I would very much appreciate it. Thanks!

I don't know why I didn't think of that, but there's an error when I compile it.
SquareRoot.java:21: cannot find symbol
symbol : method add(java.lang.String)
location: class SquareRoot
add(System.getProperty("line.separator"));
^
And the same thing happens when I try it with \n
SquareRoot.java:21: cannot find symbol
symbol : method add(java.lang.String)
location: class SquareRoot
add("\n");
^
Here's the code:
public class SquareRoot extends java.applet.Applet
     implements ActionListener
     TextField m1, m2;
     Button b;
     double i1, i2, i3, i4;
     public void init( )
          m1 = new TextField(20);
          m2 = new TextField(20);
          b = new Button("Calculate");
          add(m1);
          add("\n");  //I'm trying to add a line break here
          add(b);
          add(m2);
          b.addActionListener(this);
     }Thanks!
