I have a program that monitors real-time air waves and demodulates them into useable data. The program runs fine and with very little issues over time. The only thing I am really interested in is whether the calls to memcpy can be handled differently.

please I am new to java and i was asked to create a program that when u input an id number it bring out a name.I need as much input as possible.using dialog box method. Thanks.
So I've written up my code.
Obviously, I'm looking for easy of use and error checking. I don't
have more idea what could I do to optimize my code.
Will be glad the hear your opinions or suggestions. It's a lot of code, so bear with me.

Return the number of bits (N) that will need to be changed in order to convert an integer, X, into another integer(Y).
Constraint: 0 <= X <= Y <= 2**128
Example:

X = 2, Y = 3 => N = 1
X = 0, Y = 4 => N = 1
