FileInputStream and FileOutputStream in Java

FileInputStream

A FileInputStream obtains input bytes from a file in a file system. What files are available depends on the host environment.

FileInputStream Declaration syntax

public class FileInputStream extends InputStream

FileInputStream is meant for reading streams of raw bytes such as image data. For reading streams of characters, consider using FileReader.

FileOutputStream

A file output stream is an output stream for writing data to a File or to a FileDescriptor. Whether or not a file is available or may be created depends upon the underlying platform. Some platforms, in particular, allow a file to be opened for writing by only one FileOutputStream (or other file-writing object) at a time. In such situations the constructors in this class will fail if the file involved is already open.

FileOutputStream Declaration Syntax

public class FileOutputStream extends OutputStream

FileOutputStream is meant for writing streams of raw bytes such as image data. For writing streams of characters, consider using FileWriter.
