如何将我的结果存储到另一个数组中？

Question

我想将从二维数组获得的平均值存储到一维数组中。我不确定该怎么做！package javaprogram;import java.util.Scanner;public class program {    public static void main(String[] args) {         //a one-dimensional array to store the student names        String names[] = {"Johnson","Aniston","Cooper","Gupta",            "Blair","Clark","Kennedy","Bronson","Sunny", "smith"};        // a 2 dimentional array to store scores        int[][] scores =  { {85, 83, 77, 91,76}, {80,90,95,93,48},        {78,81,11,90,73},{92,83,30,69,87}, {23,45,96,38,59}, {60,85,45,39,67},        {77,31,52,74,83}, {93,94,89,77,97},{79,85,28,93,82},{85,72,49,75,63}};        //a 1 dimentional array to store grades        double[] grade = new double[10];        double sum=0, average=0;        for(int row=0; row<10; row++)        {            sum = 0;            for(int col=0; col<scores[row].length; col++)            {                sum = sum +scores[row][col];                average= sum/5;            }            System.out.println(average);        }    }}

Answer 1

像这样的东西？

double[] grade = new double[10];

double sum=0, average=0;

for(int row=0; row<10; row++) {

    sum = 0;

    for(int col=0; col<scores[row].length; col++){

        sum += scores[row][col];

    }

    average = sum/5;

    grade[row] = average;

}

Answer 2

做这个修改

取出average= sum/5;内循环外

将其存储在您的一维数组中，每行平均 grade[row] = sum/5;

 for(int row=0; row<10; row++)

    {

        sum = 0;    

        for(int col=0; col<scores[row].length; col++)

        {

            sum = sum +scores[row][col];   

        }

       grade[row] = sum/5;   // store it in your array each rows average      

        System.out.println(grade[row]);    

    }

请注意，由于您的所有分数都是int，因此您将获得整数平均值而不是小数平均值。
