How to print square root ?

Question

Hi...i want to print square root on command prompt and a symbol(i don't know what it's name for second symbol). But i get a problem. Below is my code. For what i understand i should use \u221A right? :-
public class Test
     public static void main(String[]args)
          try
               System.out.println("\u221A");
               System.out.println("\u00ea");
          catch(Exception e)
               e.printStackTrace();
}But the result is only question mark...can someone show me the right way and what's wrong to my code. I very appreciate to any help. Thank you.

Answer 1

but it does show up in swing components
import javax.swing.*;
import java.awt.*;
public class printsymb
     private static final String SYMBOL = String.valueOf( '\u221A' );
     public static void main( String args[] )
          display( SYMBOL );
          System.out.print( SYMBOL );
          System.out.println( 4 );
     private static void display( String symbol )
          JTextArea text = new JTextArea( symbol );
          JFrame f = new JFrame();
          f.add( text, BorderLayout.CENTER );
          enableJFrame( f );
     private static void enableJFrame( JFrame frame )
          frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
          frame.setSize( 320, 240 );
          frame.setVisible( true );
}you can always put it out like this "sqrt(someExp)" can't you?
