HashMap and int as key

Question

I am trying to build a HashMap which will have integer as keys and objects as values.

My syntax is:

HashMap myMap = new HashMap&         


        

Answer 1

For everybody who codes Java for Android devices and ends up here: use SparseArray for better performance;

private final SparseArray myMap = new SparseArray();

with this you can use int instead of Integer like;

int newPos = 3;

myMap.put(newPos, newObject);
myMap.get(newPos);
