This tutorial demonstrates the power of lambda expressions by contrasting implementations of a mathematical example using C++, Java without lambdas, and Java 8 with lambda expressions.

Like C# lambda expressions, Java 8 lambda expressions tie an argument list to a body. For example, (int x) -> x * x specifies an integer parameter that’s named x and returns the value of x squared.

In the previous two examples, an instance of the Integer class was passed to both the Function and the Consumer. The Supplier interface, however, isn’t passed anything. It simply generates a value ...

As an aside, Lombok has many other useful features implemented as annotations - @Builder, @Synchronized, and @Wither.What's more, I'm picking Lombok for the example because it's probably the best ...
