This intro to HashMaps in Java explains how to create hash maps, add and remove items, iterate, edit, and everything else you need to know about this data structure. Sometimes called dictionaries, hash tables, or associative arrays, they are used for storing key-value pairs with very quick lookup.

Would be nice to explain why use the stream API in the last example. Is there a performance benefit?

I gave that example in case people are using streams to do other things in their workflow, so they can see how to use HashMaps in a stream. I agree performance comparison would be nice.
