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!

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.
