class GFG {

// Function to add x in arr
public static int[] addX(int n, int arr[], int x)
{
int i;

// create a new array of size n+1
int newarr[] = new int[n + 1];

// insert the elements from
// the old array into the new array
// insert all elements till n
// then insert x at n+1
for (i = 0; i < n; i++)
newarr[i] = arr[i];

newarr[n] = x;

return newarr;
}

// Driver code
public static void main(String[] args)
{

int n = 10;
int i;

// initial array of size 10
int arr[]
= { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };

// print the original array
System.out.println(“Initial Array:\n”
+ Arrays.toString(arr));

// element to be added
int x = 50;

// call the method to add x in arr
arr = addX(n, arr, x);

// print the updated array
System.out.println(“\nArray with ” + x
+ ” added:\n”
+ Arrays.toString(arr));
}
}

Output:Initial Array:
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

Array with 50 added:
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 50]
