How to enable smooth rendering of objects(ex. line, circle) in applet

Hi, is there any option in Applet by which we can enable smooth rendering of simple
objects. I am drawing lines in screen, which are not so much smooth.
Have a look at attached snapshot.
Thank you.

Set the antialias rendering hint on the Graphics2D object:

Java Code:

public void paintComponent(Graphics g){
    Graphics2D g2d = (Graphics2D)g;
    g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, 
        RenderingHints.VALUE_ANTIALIAS_ON);

Hey, I am getting a compilation error.

Cannot find symbol
Symbol: method setRenderingHint(java.awt.RenderingHints.Key, java.lang.Object)

I am working in applet. I have public void paint(Graphics screen){} instead of paintComponent(Graphics g). Is this the reason of the error? what to do now?

Java Code:

Graphics2D g2d = (Graphics2D) g;

My telepathy skills lack practice, so I can't see your code to comment on why you are receiving the error (in other words, please post the appropriate code). Quick note however, I did edit my code above as the cast was supposed to be to a Graphics2D object (my bad)...which - my rusty telepathy skills tells me - might be the problem.
