    Hello.
    Apart from gridx and gridy you may need to set few more properties. Check "Java How to Program" by Deitel & Deitel. Its a wonderful book for GUI programming in Java.
    For setting the boundary of checkbox, you may use setBorder() method of JCheckBox class.

    Hint: You may need to use BorderFactory class' static method to create desired border.

    Hello.
    I am not sure about AWT.
    But yes, its certainly available in Swings. So I suggest you use swings because AWT is outdated.

    We are required to use Awt and not Swing..
    Can you tell me the particular keyword to arrange my checkbox?
    Thanks

    Both of those questions can be answered by checking the documentation.
    (The point of the assignment is to get you to practice reading documentation for code you did not write, but still must use "in practice")
