Merge two array

By using the merge sort algorthim we can achieve it the merging part of merge sort algorthim is used here

Example for Merging two array

import java.util.Arrays;

class Employee
{
    public static void main(String args[])
    {
        int arr[] = { 12, 11, 13, 5, 6, 7 };
        int arr2[] = { 12, 11};
        int arr1size = arr.length;
        int arr2size = arr2.length;
        int total = arr1size+arr2size;
        int[] temp =new int[total];
        int i = 0, j = 0;
        int k = 0;
        while (i < arr1size && j < arr2size)
        {
            if (arr[i] <= arr2[j])
            {
                temp[k] = arr[i];
                i++;
            }
            else
            {
                temp[k] = arr2[j];
                j++;
            }
            k++;
        }
        while (i < arr1size)
        {
            temp[k] = arr[i];
            i++;
            k++;
        }
        while (j < arr2size)
        {
            temp[k] = arr2[j];
            j++;
            k++;
        }
        System.out.println(Arrays.toString(temp));
    }
}
