如何要求用户在整数数组中输入10个正数，如果小于0则无效

Question

这是我到目前为止所得到的。我也不知道如何显示最小和最大，偶数和奇数输入。有人请帮忙

int value = -1;

    Scanner scanner = new Scanner(System.in);

    while(value < 0) 
    {
      System.out.print("Enter a value > 0: ");

      value = scanner.nextInt();

    }
      if(value < 0)

      System.out.println("sorry write a value > 0");

    }

这有帮助吗？

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

    Scanner value = new Scanner(System.in);

    int number =value.nextInt();

    if (number < 0 ) {
        System.out.println("Value entered less than zero");
    }
    else if (number == 0) {
        System.out.println("Value entered is equal to zero");
    } else {
        System.out.println("Value must have been greater than zero.");
    }
}
