In this java program, we are going to learn **how to find addition of one dimensional and two dimensional arrays**?

Submitted by Preeti Jain, on March 11, 2018

There are two programs: **addition of two one dimensional arrays** and **addition of two two dimensional arrays**.

class AddTwoArrayClass{ public static void main(String[] args){ // Declaration and initialization of array int a[] = {1,2,3,4,5}; int b[] = {6,7,8,9,10}; // Instantiation of third array to store results int c[] = new int[5]; for(int i=0; i<5; ++i){ // add two array and result store in third array c[i] = a[i] + b[i]; //Display results System.out.println("Enter sum of "+i +"index" +" " + c[i]); } } }

**Output**

D:\Java Articles>java AddTwoArrayClass Enter sum of 0index 7 Enter sum of 1index 9 Enter sum of 2index 11 Enter sum of 3index 13 Enter sum of 4index 15

class AddTwoArrayOf2DClass{ public static void main(String[] args){ // Declaration and initialization of 2D array int a[][] = {{1,2,3},{4,5,6}}; int b[][] = {{7,8,9},{10,11,12}}; // Instantiation of third array to store results int c[][] = new int[2][3]; for(int i=0; i<2; ++i){ for(int j=0; j<3; ++j){ // add two array and result store in third array c[i][j] = a[i][j] + b[i][j]; System.out.println("Enter sum of "+i + " " + j +"index" +" " + c[i][j]); } } } }

**Output**

D:\Java Articles>java AddTwoArrayOf2DClass Enter sum of 0 0index 8 Enter sum of 0 1index 10 Enter sum of 0 2index 12 Enter sum of 1 0index 14 Enter sum of 1 1index 16 Enter sum of 1 2index 18
