Creating a file from ByteArrayOutputStream in Java

When we are dealing with data over the line, our option is bytes and one of the handy Class in Java to deal with bytes and streams together is ByteArrayOutputStream. When ever you want to write some bytes to specific file while receiving the data you just need to use the method writeTo().  

Code to Create a file from ByteArrayOutputStream in Java:

 OutputStream outStream = null;  
 ByteArrayOutputStream byteOutStream = null;  
 try {  
   outStream = new FileOutputStream("fileNameToSave");  
   byteOutStream = new ByteArrayOutputStream();  
   // writing bytes in to byte output stream  
   byteOutStream.write(bytes); //data  
   byteOutStream.writeTo(outStream);  
 } catch (IOException e) {  
   e.printStackTrace();  
 } finally {  
   outStream.close();  
 }  

That all to create a file with specified name with incoming byte array stream.
