Problems learning streams and lambdas

I've done all sorts of reading on streams and lambdas so theoretically I understand them.  But I learn by doing, not by reading.  So I need to write some programs for it to all gel.

Does anyone know of websites with some problems to be solved with streams and/or lambdas?
