Set an array element to Null - Java

Question

I need to create an array that holds integers. I did this:

int[] arr; 
arr = new int[5];
arr[0] = 10;
arr[1] = 20;
arr[2] = 30;
arr[3] = 40;
arr[4] = 50;

I need to shift the elements to left and set the last one to Null.

for (int i = 0; i < arr.length-1; i++) 
       arr[i]=arr[i+1];
   arr[arr.length-1]= Null

I did the above but I get an error. Please help me, I need to use null, not -1 or any other number. Perhaps I need to change my elements to object of Integer, but I dont know how to. Thanks

`int` is primitive type you can not add null to it. Use `Integer` instead. — Sudhir Ojha, Jun 23 '20 at 07:01

Use the Integer type instead of primitive int. Integer can be null: was answered here
