In this portion of the Course Project we will be working with arrays. Arrays are a key part of programming and you will be using them quite often. An array can be thought of as a closet organizer for data. We will also be working with classes, which can hold arrays. You can think of a class as the closet and arrays are where you store what goes in the closet.
Put data into array(s) for stock trades and a combination of abstract classes AND concrete classes should be set up in your code. You can have the user input the data into the arrays or you can set it up so the arrays are already populated.
