Could someone give me a very elementary example in doing this?
I'm trying to write a method that takes something looks inside an array and remove a specific element from within the array at index i.

1Do you actually need to remove the element, or can you simply mark it as deleted by using a certain value (i.e. a "soft" delete)? – Tim Biegeleisen Mar 08 '16 at 02:45

2Don't use an array for this. If you want a "dynamic" array, use the best tool -- an ArrayList. – Hovercraft Full Of Eels Mar 08 '16 at 02:46

You could set the array item to null, or use ArrayUtils'
array = ArrayUtils.removeElement(array, element)
you could also fill it with a blank value of the array type. This is a very abstract question with many answers, but google is your friend.

Arrays have fixed size so deleting an element would be a costly operation.
Method 1: create a new array of size length -1 and copy all elements except the one you want to delete.
Method 2: Use ArrayList instead of arrays.
