Removing a single element from an array is not rocket science, but there is no standard function available for this task.

| With ArrayUtil significant array operations were implemented, which also fully include the list interface. We gain performance compared to standard lists as an added benefit. | With ArrayUtil significant array operations were implemented, which also fully include the list interface.
