Chapter 2 ▪ Input and Output

In this chapter, we cover the Java Application Programming Interfaces (APIs) for input and output. You will learn how to access files and directories and how to read and write data in binary and text format. This chapter also shows you the object serialization mechanism that lets you store objects as easily as you can store text or numeric data. We finish the chapter with a discussion of regular expressions, even though they are not actually related to input and output. We couldn’t find a better place to handle that topic, and apparently neither could the Java team—the regular expression API specification was attached to a specification request for “new I/O” features.

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.
