Java Program to Increment All Elements of an Array by One

This is a Java Program to Increment Every Element of the Array by One & Print Incremented Array.

Enter size of array and then enter all the elements of that array. Now using for loop we increment all the elements of the array.

Here is the source code of the Java Program to Increment Every Element of the Array by One & Print Incremented Array. The Java program is successfully compiled and run on a Windows system. The program output is also shown below.

  1. import java.util.Scanner;
  2. public class Increment_Array
  3. {
  4.     public static void main(String[] args) 
  5.     {
  6.         int n, i = 0;
  7.         Scanner s = new Scanner(;
  8.         System.out.print("Enter no. of elements you want in array:");
  9.         n = s.nextInt();
  10.         int a[] = new int[n];
  11.         System.out.println("Enter all the elements:");
  12.         for(i = 0; i < n; i++)
  13.         {
  14.             a[i] = s.nextInt();
  15.             a[i]++;
  16.         }
  17.         System.out.print("Elements of array after increment by 1:");
  18.         for(i = 0; i < n - 1; i++)
  19.         {
  20.             System.out.print(a[i]+",");
  21.         }
  22.         System.out.print(a[n-1]);
  23.     }
  24. }
