how to end a while loop with a certain variable

Question

I am making an odd or even program with a while loop. I am trying to figure out how to end the while loop with a certain number. Right now I have 1 to continue the loop, and

Answer 1

Another thing you can try is that instead of exiting the program you can just keep asking user to enter correct input and only proceed if they do so. I don't know what is your requirement but if you want to go by good code practice then you shouldn't terminate your program just because user entered wrong input. Imagine if you googled a word with typo and google just shuts off.

Anyways here is how I did it

import java.util.Scanner;

public class oddoreven {
    public static void main(String[] args) {
        int num;
        int x = 1;
        while (x == 1) {
            System.out.println("Enter a number to check whether or not it is odd or even");
            Scanner s = new Scanner(System.in);

            boolean isInt = s.hasNextInt(); // Check if input is int
            while (isInt == false) { // If it is not int
                s.nextLine(); // Discarding the line with wrong input
                System.out.print("Please Enter correct input: "); // Asking user again
                isInt = s.hasNextInt(); // If this is true it exits the loop otherwise it loops again
            }
            num = s.nextInt(); // If it is int. It reads the input

            if (num % 2 == 0)
                System.out.println("The number is even");
            else
                System.out.println("The number is odd");
            // trying to figure out how to get the code to terminate if you put in a value
            // that isn't a number
            System.out.println("Type 1 to continue, 0 to terminate");
            x = s.nextInt();
        }

    }
}
