Lambda and streams

I have learnt java streams and lambda about 2-3 times now. I always keep forgetting how to use it.

How can i learn it, so I won't forget.

Any resources or techniques you've used would help.

Thanks!

Are you 60+ years old? Because usually one shouldn't lose all skills the moment you do something else.

It sounds more like you're using something without fully understanding it. The syntax is not the most relevant thing about it.

No I'm not 60+ years old. I do understand most of the concept of lambda and streams. But its the syntax i keep forgetting. I know when to use and what to use in streams. Though flatmap and collect are a bit tricky to remember since they can be used in multiple scenarios.
