language designer This is evidenced by the number of different approaches The challenge seems to be in covering all possibilities Not only are there different sources and sinks of IO that you want to municate with files the console network connections etc but you need to talk to them in a wide variety of ways sequential randomaccess buffered binary character by lines by words etc The Java library designers attacked this problem by creating lots of classes In fact there are so many classes for Javas IO system that it can be intimidating at first ironically the Java IO design actually prevents an explosion of classes There was also a significant change in the IO library after Java io when the original byteoriented library was supplemented with charoriented Unicodebased IO classes The nio classes for new IO a name well still be using years from now even though they were introduced in JDK 14 and so are already old were added for improved performance and functionality As a result there are a fair number of classes to learn before you understand enough of Javas IO picture that you can use it properly In addition its rather important to understand the evolution of the IO library even if your first reaction is Dont bother me with history just show me how to use it The problem is that without the historical perspective you will rapidly bee confused with some of the classes and when you should and shouldnt use them Input and output Programming language IO libraries often use the abstraction of a stream which represents any data source or sink as an object capable of producing or receiving pieces of data The stream hides the details of what happens to the data inside the actual IO device The Java library classes for IO are divided by input and output as you can see by looking at the class hierarchy in the JDK documentation Through inheritance everything derived from the InputStream or Reader classes has basic methods called read for reading a single byte or an array of bytes Likewise everything derived from OutputStream or Writer classes has basic methods called write for writing a single byte or an array of bytes However you won抰 generally use the se methods they exist so that other classes can use them梩hese other classes provide a more useful interface Thus you抣l rarely create your stream object by using a single class but instead will layer multiple objects together to provide your desired f unctionality this is the Decorator design pattern as you shall see in this section The fact that you create more than one object to produce a single stream is the primary reason that Java抯 IO library is conf
