How to use JAVA to realize the traversal summation of two-dimensional arrays

This article will explain in detail how to use JAVA to achieve two-dimensional array traversal summation. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

/ * the ergodic sum of the two-dimensional array, the sales of the first group is {11,12} yuan, the second group is {21,22,23} yuan, and the third group is {31,32,33,34} yuan. Each group is an array, and three arrays are stored in an array to form a two-dimensional array sum: each group summates all elements * / public class ArrayArrayDemo_3 {public static void main (String [] args) {int [] [] arr = {{11pr 12}, {21pr 22 23}, {31m 33pm 34}}. / / define variables and save 2 summation values int sum = 0; / / summation of all elements int groupSum = 0; / / summation of each one-dimensional array for (int I = 0; I < arr.length; iSum +) {for (int j = 0; j < arr [I] .length) System.out.println +) {/ / sum the elements of one-dimensional array groupSum + = arr [I] [j];} System.out.println ("total amount per team" + groupSum); / / add the sum of each one-dimensional array to sum + = groupSum / / Sum of each unique array, clear groupSum = 0;} System.out.println ("total amount of our company" + sum) }} on "how to use JAVA to achieve two-dimensional array ergodic sum" this article is shared here, I hope the above content can be of some help to you, so that you can learn more knowledge, if you think the article is good, please share it for more people to see.
