  Input / Outputin Java ● Programs read inputs from data sources (e.g., keyboard, file, network, memory buffer, or another program) and write outputs to data sinks (e.g., display console,file, network, memory buffer, or another program). ● Java I/O (Input and Output) is used to process the input and produce the output. ● Java uses the concept of stream to make I/O operation fast. The java.io package is used for java i/o (file handling).

  Stream • A streamcan be defined as a sequence of data. • A stream is an object that either delivers data to its destination (screen, file, etc.) or that takes data from a source (keyboard, file, etc.)

  Stream cont.. • Thereare two kinds of Streams − ○ Input Stream − The Input Stream is used to read data from a source. ○ Output Stream − The Output Stream is used for writing data to a destination.

  Continue… ● Java definestwo types of streams. They are, ○ Byte Stream : It provides a convenient means for handling input and output of byte. ○ Character Stream : It provides a convenient means for handling input and output of characters.

  types of streams •There are two types of streams : • Byte Streams • Character Streams

  Byte stream • Bytestream have been designed to provide functional features for creating and manipulating streams and files for reading and writing bytes. • Bytes can transmit in only one direction. • Byte streams create binary files. • Binary files are faster to read and write because no translation need take place.

  Character stream • Characterstreams can be used to read and write 16-bit Unicode characters. • Character streams create text files. • Two kinds of character stream classes-

  Standard Streams Java providesthe following three standard streams − • Standard Input − This is used to feed the data to user's program and usually a keyboard is used as standard input stream and represented as System.in. • Standard Output − This is used to output the data produced by the user's program and usually a computer screen is used for standard output stream and represented as System.out. • Standard Error − This is used to output the error data produced by the user's program and usually a computer screen is used for standard error stream and represented as System.err.
