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

import java.util.Scanner; public class C{ public static void main(String args[]){ Scanner in = new Scanner(System.in); System.out.print("请输入二维数组x的行数:"); int a = in.nextInt(); System.out.print("请输入二维数组x的列数:...

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...

使用嵌套for循环

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; }

package retestC8;public class Summation { public static void main(String[] args) { String str[][]=new String[][]{{"1","2"},{"3","4"},{"5","6"},{"7","8"}}; //怎样将这个二维的字符串型数组里面的数值全部加起来? int sum=0; for(int...

有两个数组 x[],y[],还有一个H[][],实现方式如下 for(int i=0,i

for(int i=0,i

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...
