You will be able to convert the input string to byte array in Java. To perform this, you will need to read each byte from your InputStream and write the same into a ByteArrayOutputStream. Once done, you can retrieve the underlying byte array by calling the method toByteArray(). Let's take a sample example which is represented below. 



InputStream is = ... 



ByteArrayOutputStream buffer = new ByteArrayOutputStream();



int kRead;


byte[] data = new byte[16384];



while ((kRead = is.read(data, 0, data.length)) != -1) 


{


  buffer.write(data, 0, kRead);


}


return buffer.toByteArray();
