Overview
This chapter discusses how Java doubles up as a functional programming language. It also details the manner in which lambda expressions are used to perform pattern matching in Java. It accomplishes this, first, by explaining, in general terms, the difference between Object-Oriented Programming (OOP) and Functional Programming (FP).
