Examples of java.io.File

java.io.File
File is a class which represents a file name or directory. The file may be absolute relative to the root directory of the file system or relative to the current directory in which the program is running.
This class provides methods for querying/changing information about the file and also directory listing capabilities if the File represents a directory.
When manipulating file paths, the static fields of this class may be used to determine the platform specific separators. @see java.io.Serializable @see java.lang.Comparable
