The recommended entry point to start exploring the NIO.2 API, also known as “JSR 203: More New I/O APIs for the Java Platform” (NIO.2), is the new abstract class java.nio.file.Path. This class is a milestone of NIO.2, and every application that involves I/O operations will exploit the powerful facilities of this class. Practically, it is the most commonly used class of NIO.2, since many I/O operations are based on a Path resource. The Path class supports two types of operations: syntactic operations (almost any operation that involves manipulating paths without accessing the file system; these are logical manipulations done in memory) and operations over files referenced by paths. This chapter covers the first type of operations and introduces you to the Path API. In Chapter 4, I focus on exploring the second type of operations. The concepts presented in this chapter will be very useful in the rest of the book.
