Section 7 : Lambdas and Local variables ( Effectively Final )

This section covers the local variable and how it should used in Lambdas.
Definition of Effectively Final scope of a variable.

Section 8 : Streams API

This section covers the Streams API which is one of the important feature that got introduced as part of Java8.
How the Stream API Works Internally ?
How Collections are different from Streams ?
How to debug a Stream ?

Section 9 : Streams API Operations

This section covers different Streams API operations that can be used in Streams to achieve an objective.
Streams Operations such as :
- map()
- flatMap()
- distinct()
- count()
- filter()
- reducer()
- Map, Filter and Reduce pattern.
- max()
- min()
- limit()
- skip()
