Uses of Class
java.io.File

Packages that use File
java.io Provides for system input and output through data streams, serialization and the file system. 
java.util.jar Provides classes for reading and writing the JAR (Java ARchive) file format, which is based on the standard ZIP file format with an optional manifest file. 
java.util.zip Provides classes for reading and writing the standard ZIP and GZIP file formats. 
javax.swing Provides a set of "lightweight" (all-Java language) components that, to the maximum degree possible, work the same on all platforms. 
javax.swing.filechooser Contains classes and interfaces used by the JFileChooser component. 
javax.swing.plaf Provides one interface and many abstract classes that Swing uses to provide its pluggable look-and-feel capabilities. 
javax.swing.plaf.basic Provides user interface objects built according to the Basic look-and-feel. 
javax.swing.plaf.metal Provides user interface objects built according to the ``metal'' look-and-feel. 
javax.swing.plaf.multi The multiplexing look and feel allows users to combine auxiliary look and feels with the default look and feel.
