Java 8 Lambda

An anonymous function is a function that was declared without any named identifier to refer to it . As such, an anonymous function is usually not accessible after its initial creation. Normal function definition: function hello() { alert(‘Hello world’); } hello();

In Java, a class can contain another class known as nested class. It’s possible to create a nested class without giving any name. A nested class that doesn’t have any name is known as an anonymous class. An anonymous class must be defined inside another class. Hence, it is also known as an anonymous inner class.

Basically, the -> separates the parameters (left-side) from the implementation (right side) . The general syntax for using lambda expressions is. (Parameters) -> { Body } where the -> separates parameters and lambda expression body.
