enter an integer:
13
enter an integer:
2
enter an integer:
21
enter an integer:
40

Solution

import java.util.Scanner;
public class Question82149 {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int count = 0;
        int x = 0;
        while (x != -1) {
            System.out.println("enter an integer:");
            x = scanner.nextInt();
            if (x > 18)
                count++;
        }
        System.out.println("Total number that is greater than 18: " + count);
    }
}
