Java 8 - Syntax to represent Lambdas

Below is the syntax for representing a Lambda expression :

parameter(s) −> expression(s)

where

• parameter(s) has the following rules:

1. Optional type declaration
2. Optional comma, only for more than one parameter
3. Optional brackets, only for more than one parameter

• expression(s) has the following rules:

1. Optional curly braces
2. Optional return keyword

As quoted from the Oracle site:

"Note that a lambda expression looks a lot like a method declaration; you can consider lambda expressions as anonymous methods—methods without a name."
