Exception handling with a do-while loop in Java

Question

The algorithm should take in 3 integers to an ArrayList. If the input is not an integer, then there should be a prompt. When I execute my code the catch clause is e

Answer 1

You should to use a break; in your catch(){} like so :

try {
    inputNum = input.nextInt();
    numbers.add(inputNum);
    counter += 1;
} catch (Exception e) {
    System.out.println("invalid number ");
    break;
}

So if one input is not correct break your loop.
