Capturing lambdas
Explore how capturing lambdas function in Java 8 by understanding their interaction with static, instance, and local variables. Learn the concept of effectively final variables and why local variables used in lambdas must be final or effectively final to ensure reliable behavior during lambda execution.

A lambda expression is said to be capturing if it either accesses instance variables of it’s enclosing class or local variables (final or effectively final) from it’s enclosing scope.
A lambda expression can capture the three types of variables given below:
