How to add JPanel in to JFrame

Question

Hello,
i have 2 classes in java.
1)a class that extends Jframe
2)another that extends JPanel

I try to add the JPanel in the JFram class , it looks something like this:

public static void main(String args[]) { // the main is in the JFram class
        Othello Oth= new Othello();    // instance of the JFram class
        Oth.setLocation(250, 150);
        OthelloBoard OB = new OthelloBoard();     // instance of JPanel class
        Oth.add(OB);
        Oth.setVisible(true);

but only the JFrame got shown and it seems that the JPanel i added did not go onto the JFrame (i am using NetBeans).

How can I solve this problem??

Thank you...

What is your layout??

I didn't specify the layout for form or panel.

I applied the santosh dhanawade solution but it didn't work.

this is the two main clasess:

Othello.Java

C#

public class Othello extends javax.swing.JFrame {

    OthelloBoard OB;

    /** Creates new form Othello */

    public Othello() {

        initComponents();
        OB = new OthelloBoard();
        add(OB,BorderLayout.CENTER);
        setVisible(true);
}

public static void main(String args[]) {


            Othello Oth= new Othello();
            Oth.setLocation(250, 150);




    }
