Thread: Issue with while loops...beginner question

This problem is inputting 10 numbers, and printing th My solution is working except it runs forever when I input anything other than an int. Can someon tell me whatI've done wrong?

package com.company;
 
import java.util.Scanner;
 
public class Main {
 
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
 
        int count = 1;
        int sum = 0;
        while (count<=10) {
            System.out.println("Enter number #"+count);
            boolean hasNextInt = scanner.hasNextInt();
 
            if (hasNextInt){
                int number = scanner.nextInt();
                count++;
                sum +=number;
 
            }
 
            else {
                System.out.println("Invalid Input");
                continue;
            }
            scanner.nextLine();
 
 
        }System.out.println("the sum of these numbers is "+sum);
        scanner.close();
    }
}

If the Scanner has an invalid value (say hasNext... is false), it will keep that value until some next method reads and clears it.
Be sure the code reads and rejects any invalid value before trying to read and process the next user input.

well I thought about it and I think removing the "continue;" fixes the issue
