Question

public void withdraw(double amount) throws InsufficientFundsException{
if (amount > this.balance) throw new InsufficientFundsException("Sorry, you have insufficient funds!");
       else {
this.balance = this.balance - amount;
}
}
}

can that be put in try-catch blocks? if so how does it look

Answer 1

It can be put in try and catch block since it may throw InsufficientFundsException. InsufficientFundsException is a user defined exception so it should be defined in which it extends Exception class. An example of how it will look is given below:

try{

withdraw(1000);

}

catch(InsufficientFundsException e)

{

System.out.println(e);

}
