Part 2: Mutual Fund InvestorTrack App (50 pts)

• For the next part of your lab, you will use the BST class you wrote above to create an application that helps users to track investments in mutual funds.
• Using the starter code below, fill in the empty method bodies. Note that you are not allowed to add any additional methods or member variables to these class (including no DecimalFormat member variables) or you will not receive credit for this part of the assignment.
• You may not make any additional import statements at the top of any of the below files

List.java

• Add the following methods to your List.java class from Lab 3:

/** * Points the iterator at first * and then advances it to the * specified index * @param index the index where * the iterator should be placed * @precondition 0 < index <= length * @throws IndexOutOfBoundsException * when precondition is violated */ public void iteratorToIndex(int index) throws IndexOutOfBoundsException{ //fill in here } /** * Searches the List for the specified * value using the linear search algorithm * @param value the value to search for * @return the location of value in the * List or -1 to indicate not found * Note that if the List is empty we will * consider the element to be not found * post: position of the iterator remains * unchanged */ public int linearSearch(T value) { return -1; } 

CustomerInterface.java

• Note that you may add as many additional methods and variables as you would like to the below starter code
• You must use the given BSTs and List objects given in the starter code, and no other structures
• You may not make any additional import statements at the top of this file
• You must use your BST class from Part 1 of this lab and your List class from Lab 3 to receive credit.
