Java Tutorial : Java Exception handling (Custom Exception or User defined Exception-Version2) 
InsufficientBalanceException.java
class InsufficientBalanceException extends Exception
{

    public InsufficientBalanceException(String message)
    {
        super(message);
    }

}
CustomExceptionDemo.java
public class CustomExceptionDemo
{

    public static void main(String[] args)
    {
        try
        {
            CustomExceptionDemo customExceptionDemo = new CustomExceptionDemo();
            customExceptionDemo.withdrawMoney(20000);
        }
        catch (InsufficientBalanceException insufficientBalanceException)
        {
            insufficientBalanceException.printStackTrace();
            System.out.println("message = "
                    + insufficientBalanceException.getMessage());
        }

    }

    public void withdrawMoney(int amount)
            throws InsufficientBalanceException
    {
        if (amount > 10000)
        {
            throw new InsufficientBalanceException(
                    "Your account does not have enough money to withdraw.");
        }
        else
        {
            System.out.println("Successfully withdrawn.");
        }

    }
}
Output
InsufficientBalanceException: Your account does not have enough money to withdraw.
    at CustomExceptionDemo.withdrawMoney(CustomExceptionDemo.java:25)
    at CustomExceptionDemo.main(CustomExceptionDemo.java:9)
