想了解Java二维数组计算集合总结的相关内容吗，彬菌在本文为您仔细讲解Java二维数组计算集合的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：Java,二维数组，下面大家一起来学习吧。
public class CrossSum{
public static void main(String args[]){
int [][]a = {{1,2,3,4,5},
{6,7,8,9,10},
{11,12,13,14,15},
{16,17,18,19,20},
{21,22,23,24,25}} ;
int transverse =0; //横
int vertical =0; //竖
for(int i = 0; i < 5; i++){
transverse = transverse+ a[2][i]; //通过下标访问
}
for(int j = 0; j < 5; j++){
vertical = vertical+ a[2][j];
}
System.out.println("5*5数组十字和为"+(transverse+vertical));
}
}
public class LeftSum{
public static void main(String args[]){
int [][]a = {{1,2,3,4,5},
{6,7,8,9,10},
{11,12,13,14,15},
{16,17,18,19,20},
{21,22,23,24,25}} ;
int sum =0;
for(int i = 0; i < 5; i++){
sum = sum+ a[i][i];
}
System.out.println("5*5数组↘="+sum);
}
}
public class RightSum{
public static void main(String args[]){
int [][]a = {{1,2,3,4,5},
{6,7,8,9,10},
{11,12,13,14,15},
{16,17,18,19,20},
{21,22,23,24,25}} ;
int sum =0;
for(int j = 4; j >=0; j--){
sum = sum+ a[j][j];
}
System.out.println("5*5数组↙="+sum);
}
}
