My end goal is for it to be transmitted over a network. this is the question posed to us:
We need to be able to send more advanced structures over the network. How can we convert these structures to the byte arrays supported by the networking classes?
How is an int represented in Java? Specifically: How many bytes are used to represent an int? What is the relevance of each byte? How can an int be converted into a byte array?
Write a method to convert an int into a byte array.
Write a method that converts the byte array back into an int.
Write a method that returns the size of the byte array needed to store an int.
