jAvA两个二维数组相加

int[][] list1 = {{1, 2, 3}, {1, 2, 3}, {1, 2, 3}}; int[][] list2 = {{1, 2, 3}, {1, 2, 3}, {1, 2, 3}}; int[][] result = new int[3][3]; for(int i=0; i

public int sum(int[][] a2){ int sum = 0; for(int i=0;i

二维数组的话,必须循环行和列,之后求总和即可: public class Test { public static void main(String args[]) throws ParseException { int [][]a = {{1,2,4,5},{6,7,8,9},{10,11,12,13},{14,15,16,17}}; int sum =0; //设置sum为0,方便计算...

使用循环将值遍历进行相加 例:int[] arr={1,2,3,4,5}; int sum=0; for(int a:arr){ sum+=a; }

for(int i=0,i

public static void main(String[] args) throws NoSuchAlgorithmException { int[][] n1 = {{1,2},{2,3}};int[][] n2 = {{1,2},{3,4}};addMatrix(n1,n2);}public static int[][] addMatrix(int[][]a, int[][]b) {int[][]c=new int[2][2];System...

你这样当然会报错,不说你后面那个sum,你就在循环里面定义,那岂不是每次都不一样,每次都是一个新的sum

String[] arrStr1 = { "0", "1", "2" }; String[] arrStr2 = { "A", "B", "C" }; String[][] arrs = { arrStr1, arrStr2 }; for (int i = 0; i < arrs.length; i++) { String[] arrStr = arrs[i]; for (int j = 0; j < arrStr.length; j++) { Sy...

import java.util.ArrayList; import java.util.List; public class KK { public static void main(String[] args) { // Object[][] actualResult = new Object[10][1]; // String[][] expectedResult = new String[5][1]; 这两句就相当于 Objec...
