How to delete an element from an array?

Answer 1

Basic Java arrays are fixed length, you cannot remove elements. Try using an ArrayList instead.

Answer 2

As John indicates basic arrays can't be resized. This answer describes a function you can use to create a new array without the element, and also indicates ArrayList:

Answer 3

I skipped ArrayUtils because you're importing an entire library to do something better done directly.

"There are alternatives in the form of 3rd-party libraries (e.g. Apache Commons ArrayUtils), but you may want to consider whether it is worth adding a library dependency just for the sake of a method that you could implement yourself with 5-10 lines of code."

... or just use a list.

Answer 4

array = ArrayUtils.removeElement(array, element)
