I'm so thankful guys, I'm a new learner in java so I was not familiar with Exception syntax, I will try to learn it. TANX

Answer 2

Check each character in your input string and if its something else, throw an exception or demand another input.

Answer 3

This code snippet only accepts ints (whole numbers) and obviously put this in the main or some other method

Scanner usrInput = new Scanner(System.in);
int number = 0;

try {
number = usrInput.nextInt();
} catch(Exception ValueError) {
System.out.println("Incorrect input");
}
