  // Action methods
  public boolean chargeIt(double price) {       // Make a charge
    if (price + balance > (double) limit)
      return false;      // Not enough money left to charge it
    balance += price;
    return true;      // The charge is accepted
  }
  public void makePayment(double payment) {      // Make a payment
    balance -= payment;
  }
  public void print() {                        // Print a card's info
    System.out.println("Number = " + getNumber());
    System.out.println("Name = " + getName());
    System.out.println("Bank = " + getBank());

How do you run the programme? I cannot see any main method? You should run a class that has a main method in it.

The problem doesnt seem to be in this class.
Its probably becuause of the code that you are calling this class from.

Can you post that.
And also the definition of the interface you are implementing in this class.

Same here. There must be another class that has a main () method - search for that one and run it.

Searching will be easier if you have some IDE like Eclipse, so download it - www.eclipse.org

>>this is the creditcard class file:

You're trying to post the binary. You should be posting the source code *of the class calling the CreditCard class*
