Simple tool class for the int array of Java IntArrayUtil1.0

Array out-of-bounds exceptions are really annoying and annoying. Collections are great tools, and it's a little overkill to handle small data in collections every time.

Below is a simple Intarrayutil tool class (humble degree, oneself all want to cover face, do not know to take this thing water own blog, will not be beaten by people,/manual funny).
