This section provides you an example that converts input stream to byte. And what is input stream and converting it into bytes.

Convert InputStream to Byte

In this example we are going to convert input stream to byte. Here we are going to read input stream and converting it into bytes. To do so first read the input stream from dos prompt then store it into an integer. Finally type cast the integer value into byte.

The System class provides references for the standard input, output and error streams. They are given below:

1.InputStream : This is used to take the input stream .The System class provides references for the standard input by System.in.

2.OutputStream: This is used to show the output stream. The System class uses System.out stream to refer to the standard output.

3.OutputStream: This is used to show the error as output stream. The System class provides references for the standard output by System.err.

The code of the program is given below:


import java.io.*;

public class InstramToByteExample

{

public static void main(String args[]) throws IOException

  {

  int inputStream=System.in.read();

  int i=0;

  if (inputStream != -1) 

  {

  byte bValue = (byte) inputStream;

  System.out.println("The value of byte array"+bValue);

  }

  }

}

The output of the program is given below:

C:\rajesh>javac InstramToByteExample.java

C:\rajesh>java InstramToByteExample
