ByteArrayOutputStream

import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.IOException;


// The ByteArrayOutputStream class stream creates a buffer in memory and all the data sent to
// the stream is stored in the buffer.Following constructor creates a buffer of 32 byte:

//OutputStream bOut = new ByteArrayOutputStream()
//OutputStream bOut = new ByteArrayOutputStream(int a)

//Methods

//public void reset()
//public byte[] toByteArray()
//public String toString()
//public void write(int w)
//public void write(byte []b, int of, int len)
//public void writeTo(OutputStream outSt)
