计算输入数字的总和和平均值，并在 Eclipse 中对数字进行排序

Question

问题：编写一个程序，读取用户的五个整数。程序将计算并输出

以下是关于这五个数字的统计数据：

• The sum of all of the positive numbers (greater than zero).

• The sum of all of the non-positive numbers (less than or equal to zero).

• The sum of all five numbers.

• The average of all of the positive numbers (greater than zero).

• The average of all of the non-positive numbers (less than or equal to zero).

• The average of all five numbers.

这是我的代码：

package assignment_09_20_2018;

import java.util.Scanner ; 

public class LAB_Assignment_09_20_2018 {

    public LAB_Assignment_09_20_2018() {

        // TODO Auto-generated constructor stub

    public static void main(String[] args) {

        // TODO Auto-generated method stub

        int length; 

        Scanner input = new Scanner(System.in) ;

        //opens scanner

        System.out.println("Enter 5 numbers: ") ;

        length = input.nextInt() ; 

        Int[] numbers = new Int[length]

    }

} 

我班上有人说要使用数组和 for 循环，但我不知道如何使用，请帮忙
