public class File
extends Object
implements Serializable
Instances of this class represent the name of a file or directory on the host file system. A file is specified by a pathname, which can either be an absolute pathname or a pathname relative to the current working directory. The pathname must follow the naming conventions of the host platform.
The File class is intended to provide an abstraction that deals with most of the machine dependent complexities of files and pathnames in a machine-independent fashion.
Note that whenever a filename or path is used it is assumed that the host's file naming conventions are used.
