Coding part 3

Last week for working our assignment is about how to save the file into .DAT file. at first we got a lot of problem in this part because we don't to understand about how to do the serializable part because we haven't learn that thing in Programming 1 moreover we cannot decide to use buffer writer or using input stream and output stream ..Finally we got help from out senior about this problem .. he explain about the seralizable and help us to decide using input and output stream for saving the data. After that we can continue our work because we already learn about how to do saving into the .DAT file. ^^
