Wraps an existing OutputStream and writes big-endian typed data to it. Typically, this stream can be read in by DataInputStream. Types that can be written include byte, 16-bit short, 32-bit int, 32-bit float, 64-bit long, 64-bit double, byte strings, and MUTF-8 encoded strings.
1. Declare a DataOutputStream named myDataOutputStream.
2. In the MainActivity.java file, in the onCreate method, add the line below. This will initialize the myDataOutputStream object to null.
myDataOutputStream = null;
3. Compile and run!
