java - java中奇数和偶数循环

Question

我如何重复要求用户输入一个输入，直到用户输入负数。如果用户输入负数或者0，程序就会结束？

import java.util.Scanner;
public class OddEvenInt {

    public static void main(String args[]) {

        Scanner s = new Scanner(System. in );
        int x;

        do {
            System.out.println("Enter an integer to check if it is odd or even ");
            x = s.nextInt();

            if (x % 2 == 0)
                System.out.println("You entered an even number.");
            else
                System.out.println("You entered an odd number.");
        } while (x % 2 == 0);
    }
}

你必须更改 while 子句:

while (x>0)
