Java Java Data Structures Exploring the Java Collection Framework Maps

For getCategoryCounts, why do we have to create a map with an Integer object rather than a primitive type int?

The task is to create a function that makes a map with categories and the amount of times they're listed. I completed the challenge after changing my map to Map<String, Integer> rather than Map<String, int>

I thought autoboxing would convert a primitive type to an object? Does that not work for Maps?

It's not a dire question, I'm just curious, thanks!
