If memory could last forever, we would never need to store information on a disk Until that day arrives, you ll need to save information processed by your program to a disk and efficiently retrieve that information from the disk Java has a variety of file and stream classes designed specifically to handle the storage and flow of information to and from a disk File classes let your program interact with a computer s file system, and stream classes focus on managing the flow of bytes between your program and the file system You ll learn how to use both kinds of classes in this chapter

Each file has properties that describe the file The file system determines the kinds of properties that describe a file; however, typically they include the file s name, permissions to access the file, and the date and time when the file was last updated The three commonly used file permissions are read/write, read-only, and execute The read/write permission signifies that a program can read the contents of the file and write information to the file The read-only permission gives your program the right to read the contents of the file, but not to write to the file The execute permission means the file contains a computer program Files are organized in a series of directories and subdirectories, sometimes called folders The topmost directory is called the root directory It is from here that the hierarchy of subdirectories begins Collectively, these directories and subdirectories are referred to as the directory structure, which is created by the administrator who is responsible for maintaining the secondary storage device
The File Class
The File class is contained in the javaio package and defines the methods you use to interact with the file system and to navigate the directory structure, much the same way you interactively move from one subdirectory to another You create an instance of a File class by using one of three constructors, as shown here:
File file1 = new File(String directory); File file1 = new File(String directory, String fileName); File file1 = new File(File directoryObject, String fileName);
The first constructor requires that you pass it a path to the file Many times the path is a directory hierarchy that ends with the subdirectory needed by your program For example, c:\junk\test is a directory path that leads to the test subdirectory within the junk directory of the C drive The second constructor requires two parameters The first parameter is the directory path, and the second parameter is the name of a file contained in the last subdirectory on the path Let s say the directory path is c:\junk\test and the filename is demojava If we pass these to the second constructor, we are telling Java that the demojava file is located in the c:\junk\test subdirectory The third constructor is very similar to the second constructor, except the directory path is passed as an instance of the File class instead of as a string
