This project is an attempt at making optimized Maps that uses Integers as keys.

This project is far from being finished. Currently, IntMaps should be used in production as some of the Map's features are not optimized / implemented.

The IntMap works by creating an array with the specified capacity (max key + 1). A more advanced IntMap class will maybe be implemented in the future.

Lets for example, create an IntMap called myIntMap that has a capacity of 10 elements and contains Strings:

// 10 = the max key index, not the capacity
IntMap<String> myIntMap = new IntMap(10);
myIntMap.put(1, "hello world!");
myIntMap.put(5, "my very good string.");
myIntMap.put(11, "why not me?"); // Causes IndexOutOfBoundsException

String myString = myIntMap.get(5);

For example, you could use IntMaps in Minecraft GUIs to support gui slots without any items while still storing the items efficiently.
