In this video, we will see the method reference using the double colon operator.

We use lambda expressions to write the implementation logic for the abstract method of the functional interfaces.

Sometimes, the functional interfaces call the extincting methods only. In these cases, instead of writing lambda expressions, we can refer to the existing methods.

Class can have static methods or instance methods, by using the method reference we can refer to both types of methods.

Watch this video to learn how we can use method reference with static methods and instance methods with a few examples.
