我想將從二維數(shù)組獲得的平均值存儲到一維數(shù)組中。我不確定該怎么做！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); } }}

像這樣的東西？
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;
}

做這個修改
取出average= sum/5;內(nèi)循環(huán)外
將其存儲在您的一維數(shù)組中，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]);
}
請注意，由于您的所有分數(shù)都是int，因此您將獲得整數(shù)平均值而不是小數(shù)平均值。
