# Java program to addition of one dimensional and two dimensional arrays

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**.

## 1) Addition of two one dimensional arrays in java

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

## 2) Addition of two two dimensional arrays in java

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
