help with - illegal character: \160

I'm an absolute absolute newbie both to programming and java. I'm trying to learn to program in java on an iMac 400Mhz 320mb ram using mac os x 10.3.4

i was trying a simple program called NineSquares, i've put the code and the error message of illegal character: /160 below. any help would be highly appreciated.

thank you,
Ujwala

package NineSquares;

import javax.swing.JFrame;

public class NineSquares {
* public static void main( String args[]) {
** JFrame = myFrame = new JFrame("Nine Squares");
** myFrame.setVisible(true);
** myFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CL OSE);
*}
}

and the error message i keep getting is
-bash-2.05b$ javac firstone/NineSquares.java
firstone/NineSquares.java:7: illegal character: \160

Should your main() function be inside your class? That's typically outside a class, isn't it? An error like that (assuming it is an error) is the sort of thing that could cascade down and cause a whole bunch of errors like what you've got here.

actually, the main-method must be within a class.
but on to the various things i see: the '*' shouldn't be there. and 'JFrame = myFrame = new JFrame("Nine Squares");' should be 'JFrame myFrame = new JFrame("Nine Squares");'

There should be no '=' at that point. other than that, i see no errors.
