Question

我一直在研究这个程序，它应该取一个用户输入的整数列表，程序会说明输入数字的最大值，最小值和平均值。平均部分工作正常，但由于某种原因，当程序达到最大和最小部分时它只是跳过它们。

/*
Program that takes a list of numbers entered by the user and 
states the largest, smallest, and average of these numbers.
*/
package main1;

import java.util.Scanner;

/**
*
* @author M.Jalil
*/
public class Main1 {

   /**
    * @param args the command line arguments
    */
   public static void main(String[] args) {

    int next; // next number entered by user
    double min = 100; // initialized min
    double max = 0; // initilized max
    double sum; //sum of numbers entered by user
    int numbers; // amount of numbers entered by user
    double average; //calculated average of numbers entered by users

    System.out.println("Enter a list of positive numbers.");
    System.out.println("Enter a negative number when you're done.");

    Scanner kb = new Scanner(System.in);
    next = kb.nextInt();
    numbers = 0;
    sum = 0;

    //finds the sum of all numbers and amount of numbers entered
    while (next >= 0) {
        sum = sum + next;
        numbers++;
        next = kb.nextInt();
        int[] list = new int[numbers]; // an array list of the numbers entered
        list[numbers] = next;

        // checks if number entered is bigger than the max number and assigns the larger number to max
        if (list[numbers] > max) {
            max = list[numbers];
            System.out.println("Max number: " + max); // displays maximum number ||**ignored??**||
        }
        //checks if number entered is less than the min number and assigns the smaller number to min
        if (list[numbers] < min) {
            min = list[numbers];
            System.out.println("Min number: " + min); //displays minimum number  ||**ignored??**||
        } 

    }
    average = sum / numbers; // calculates average

    System.out.println("The average is: " + average);

}

}

我已经标记了被忽略的部分打印行，并且没有按照预期显示在屏幕上。任何人都可以看看这个并帮助我吗？我觉得问题可能与我的参数有关，但我不确定是怎么回事。提前感谢任何信息或建议。

程序的某些部分未被“忽略” - if语句中的条件必须在运行时等于false

为什么我的程序部分被忽略了？
