It's just 3 extra lines lol.
assuming you were talking to me, it's not just "3 extra lines". it's an entire library of code being imported to your program that you're not fully using. it wastes memory and it's not good programming practice. import what you need as you need it. that would be like importing the entire AWT library if you're only going to use, say, a list box. just import the list box.
anyway on the topic of java, I learned sequential sorting (laughably easy), and sequential searching today. tomorrow I learn bubble sorting, binary searching and hopefully how to read from a file.
