A JFrame can have a JApplet as content. Simply make the class a JApplet, and add the main function like what you see here:
Hope this helps!

// from http://www.devx.com/tips/Tip/16650
public class MyApplet extends JApplet {
...
public static void main(String[] args) {
Component applet = new MyApplet();
JFrame frame = new JFrame("My applet, as application");
frame.getContentPane().add(applet);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.pack();
frame.show();

I found this did not work.
What did work was
- creating the applet as a JApplet not component
- calling init() explicitly
- using setVisible(true) & setSize(x,y)

I face a tough problem to convert applet to application, can some one help me?
Here is my applet code:

I face a tough problem
As you said it is a dificult problem and it is your so please do your homework and only if you get into certain difficulties make another post. We are not here to do whole your homework. More info here

Thanks. I have already resolved this problem myself /w 5hrs...Wow....Tired
Sorry to disturb you all :):)

pls can u tell me how to convert java application(swing jframe...) into applet with two or three lines.
I tried that mtd first mtd; cant figure out this
- creating the applet as a JApplet not component
- calling init() explicitly
- using setVisible(true) & setSize(x,y)
if u could show me the code dat would be great help!
tx :)
