Note: Binary search is required in the solution

CS 2003 Fundamentals of Algorithms and Computer Applications Implementing the SortedList Class In this lab you will write a program that will complete the SortedList Class, using an ArrayList private data variable, in the SortedList.java file. Your SortedList class must implement the SortedListinterface and provide default and copy constructors. The locateIndex method must be implemented with the Binary Search algorithm. You will also need the following files: two interfaces: BasicListInterface.java and SortedList Interface.java. the files TestSortedList. java, Shape. java, Rectangle. java, Square. java and Disk.java that are used to test your work.
