Array

The simplest way to start thinking about an array is as a collection, or a set of elements. In programming, these elements may be constants, variables, functions and pointers.

Java - This project will allow you to compare & contrast different 4 sorting techniques, the last of which will be up to you to select. You will implement the following: Bubble Sort (pair-wise) Bubble Sort (list-wise) [This is the selection sort] Merge Sort Your choice (candidates are the heap, quick, shell, cocktail, bucket, or radix sorts) [These will require independent research) General rules: Structures can be static or dynamic You are not allowed to use built in methods that are direct or indirect requirements for this project – You cannot use ANY built in sorting functions - I/O (System.in/out *) are ok. All compare/swap/move methods must be your own. (You can use string compares) Your program will be sorting names – you need at least 100 unique names (you can use the 50 given in project #3) – read them into the program in a random fashion (i.e. not in any kind of alpha order). *The more names you have, the easier it is to see trends in speed. All sorts will be from…
