Java 我试图创建一个程序，平均数字，但无法计算出如何添加用户输入的数字在一起

我是AP计算机科学专业的学生，学习Java。在参加本课程之前，我学习了JavaScript，但我在理解如何完成这段代码时遇到了困难。我的老师在休假，我们的下属不是程序员。谢谢你的帮助。我的老师要我们发表评论来解释一切。 这是我的密码：

package com.company;

//导入所需的scanner类和任何其他可导入类

导入java.util.*

公共班机{

public static void main(String[] args) {
    //Asks a question and lets the user input an answer, saved as the int Dividend
    System.out.println("How many numbers do you want to average?");
    Scanner dividend = new Scanner(System.in);
    int Dividend = dividend.nextInt();

    //this is a variable set in order to make the while statement work for any number
    int change = 0;

    //Asks for the numbers that should be averaged
    System.out.println("Enter the numbers to find their average: ");

    /*This is saying that while change is less than the amount of numbers being averaged,
      continue to provide an input for numbers*/
    while (change <= Dividend) {
        int Num = 0;
        int nums = 0;
        Scanner num = new Scanner(System.in);
        //I am trying to add the input to num so I can average them
        nums = num.nextInt();
        Num += nums;
        /*this is making sure that change is letting the code run through the exact amount of necessary times
          in order to input the correct amount of numbers*/
        change++;

        //once all of the numbers have been put in, average them
        if (change == Dividend) {
            System.out.println("Average: " + Num / Dividend);
        }
        System.out.println(Num);
    }


}

publicstaticvoidmain（字符串[]args）{
//询问一个问题并允许用户输入一个答案，另存为整数
System.out.println（“您希望平均多少个数字？”）；
扫描仪红利=新扫描仪（System.in）；
int divident=divident.nextInt（）；
//这是一个变量集，用于使while语句适用于任何数字
int change=0；
//询问应该平均的数字
System.out.println（“输入数字以找到它们的平均值：”）；
/*这意味着，虽然变化小于平均数，
继续为数字提供输入*/
虽然（更改您可以使用
ArrayList
存储所有用户输入，然后对其进行迭代以求平均值。
我修复了您的问题，因此它现在添加了所有数字，但仍然不确定我添加了多少部分
nums=nums+num.nextInt（）；
因此它将合计所有num

如果您希望在下方的底部有一个工作参考，我也创建了我的解决方案

public static void main(String[] args){
    int change = 0;//Total Numbers It think
    int nums = 0;//Sum

    System.out.println("Enter the numbers to find their average: ");
    Scanner num = new Scanner(System.in);//Should be moved out of loop so its not initialized every time

    int Dividend=1;//I had to declare to run it
    while (change <= Dividend) {//not sure why your comparing these

        nums = nums + num.nextInt();//Total Sum
        change++;//Total nums

        if (change == Dividend) {
            System.out.println("Average: " + nums / Dividend);
        }
        System.out.println(nums);
    }
}

你能解释一下什么是变化吗？还有什么红利是它没有公布的对不起，我的一些代码没有复制，下面是完整的代码：我回顾了我的代码，并以你的引用为指导解决了问题，我每次循环运行时都像你说的那样初始化扫描仪，每次都将变量Num重置为0。我不知道为什么我会包含NUM，但是无论如何，非常感谢您的帮助。没有问题了问题请告诉我，但是如果您可以通过单击问题旁边的复选框接受答案，这样其他人就不会认为这个问题仍然是开放的。还可以查看java命名约定这里是一个参考，我注意到一些大写的变量s
public static void main(String[] args){
    int sum = 0;
    int countOfNumbers = 0;//Tthe same as your change im guessing

    System.out.println("Enter the numbers to find their average type stop to quit: ");//Added stop statement
    Scanner scanner = new Scanner(System.in);//Should be moved out of loop so its not initialized everytime

    while (scanner.hasNext()){//Ensures there is something to check
        String next = scanner.next(); //Pull next Value
        if(next.equalsIgnoreCase("Stop"))//This will prevent looping forever
            break;
        sum = sum + Integer.valueOf(next); //Get total sum
        countOfNumbers++; //Increment total numbers
        System.out.println("The Sum is:"+sum
                +"\nThe count of Numbers averaged is:"+countOfNumbers
                +"\nThe Average is:"+sum/countOfNumbers);//Print info 
    }
    System.out.println("Done Averaging Goodbye");
}
