24.20 java.io.FileOutputStream (JDK 1.0)

This class is a subclass of OutputStream that writes data to a file specified by name, or by a File or FileDescriptor object. write() writes a byte or array of bytes to the file. To write binary data, you typically use this class in conjunction with a BufferedOutputStream and a DataOutputStream. To write text, you typically use it with a PrintWriter, BufferedWriter, and an OutputStreamWriter. Use close() to close a FileOutputStream when no further output will be written to it.
