Issue with logic and Loop in Java

Question

I started coding small program in Java. I wanted to exercise try-catch block, but i did not even come to that part and got stuck on loop part. I know this is very basic loop

Answer 1

Maybe you can try the following code. In your code , it's not need to use iteration.

choice = input.nextInt();
while (choice != 1 && choice != 2) {
    System.out.println("Invalid entry, press 1 or 2");
    choice = input.nextInt();
}
