How can you programmatically recreate an array from scratch?

In Android (Java or Kotlin), to recreate an array from scratch, you can simply create a new array of the required size, since arrays have a fixed size and cannot be resized after creation.

Example in Java:

int[] array = {1, 2, 3};
// Recreate array from scratch
array = new int[5]; // new array of length 5, filled with zeros

Example in Kotlin:

var array = arrayOf(1, 2, 3)
// Recreate array
array = arrayOfNulls<Int>(5) // array of 5 null elements

If you need to clear the array and fill it with new values, create a new array and assign it to the variable. Arrays in Java and Kotlin have a fixed size, so "recreating" means creating a new array.
