What is Lambda Expression?

A lambda expression is a anonymous method with more compact syntax that also allows the omission of modifiers, return type, and in some cases parameter types as well. Before lambda expressions, the anonymous methods are written inside the anonymous classes which are many lines of compare to the single line lambda expression.

What is Functional Interface?

An interface which has only one abstract method is known as the functional interfaces. Functional interface can have any number of non-abstract methods, but only one abstract method must be present. @FunctionalInterface annotation used for writing the functional interfaces. However, this annotation is not mandatory.
