![OutputStream class
OutputStream class is a subjective category.It is the superclass of all sessions
comprising an outcome stream of bytes. An output stream allows output bytes
and delivers them to some sink.
1) public void write(int)throws IOException: current output stream will contain
byte due to this code
2) public void write(byte[])throws IOException: current output stream will
contain an array of byte due to this code
3) public void flush()throws IOException: clears out the current output stream
4) public void close()throws IOException: closure of the current output stream
InputStream class
InputStream class is an subjective category. It is the superclass of all sessions
comprising a port stream of bytes.
1) public abstract int read()throws IOException: returns -1 at the end of the file
and it reads the next byte of data from the input stream.
2) public int available()throws IOException: number of readable bytes from
the current input stream can be estimated
3) public void close()throws IOException: closure of the current input stream
Java File Output Stream class
Java File Output Stream is an outcome flow for composing information to a data
file.
If you have to create basic principles then use FileOutputStream.Instead, for
character-oriented information, choose FileWriter.But you can create byte-
oriented as well as character-oriented information.](https://image.slidesharecdn.com/whatisjavainputandoutputstream-160601101111/85/What-is-java-input-and-output-stream-2-320.jpg)

Java File Input Stream class
Java File Input Stream category acquires feedback bytes from a data file.It is
used for studying sources of raw bytes such as picture information. For
studying sources of figures, consider using FileReader.

What is java input and output stream?
- 1. What is Java input and output stream? What is Java input and output stream? Java I/O (Input and Output) is used to process the feedback and produce the outcome based on the feedback. Java uses the idea of circulation to make I/O function fast. The java.io package contains all the sessions required for feedback and outcome functions. file handling in java can be performed by java IO API. Stream A stream is a series of information. In Java stream is comprised of bytes. Like a water flow stream; it is called a stream as it continues with the flow . In java, 3 sources are created for you instantly. All these sources are connected with system. 1) Program.out: conventional output stream 2) Program.in: conventional input stream 3) Program.err: conventional error stream OutputStream Java program uses an outcome circulation to write information to a location, it may be a knowledge file,an range,peripheral system or outlet. InputStream Java program uses a port circulation to read information from a source, it may be a knowledge file,an range,peripheral system or outlet.
