$14\mathrm{.}2$ Applied Lab $3\mathrm{.}2$: Mutual Fund App

In this Lab we use our BST to create an application that helps users to track investments in mutual funds.

Step $1$: Setup

$1.$ Copy your updated LinkedList class from Applied Lab $3\mathrm{.}1$ into the LinkedList. java file below.

$2.$ Copy your updated BST class from Lab $12$ into the BST $.$ java file below.

$3.$ Then update your BST method inOrderString$()$ to remove: $+"$

$"($plus newline$).$

$4.$ Also update your BST method inOrderString$($Node node, StringBuilder inOrder$)$ to change the added $""($space$)$ to $"$

$"($newline$).$

Step $2$: Implement the MutualFund class

Using the starter code in MutualFund. java, fill in the empty method bodies.

$-$ Note that you are not allowed to add any additional methods or member variables to this class $($including no DecimalFormat member variables$)$ or you will not receive credit.

$-$ You may not make any additional import statements at the top of the file.

Step $3$: Implement the MutualFundAcount class

Using the starter code in MutualFundAccount $.$ java, fill in the empty method bodies.

$-$ Note that you are not allowed to add any additional methods or member variables to this 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 the file. Step $4$: Implement the CustomerInterface class

Using the starter code in CustomerInterface $.$ java, complete the file to match the Sample Outputs.

$-$ The CustomerInterface class must read all the contents of the mutual$\_$funds.txt file.

$-$ You may add as many additional methods and variables as you would like to the below starter code.

$-$ You must use the given BST 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 Lab $12$ and your LinkedList class from Applied Lab $3\mathrm{.}1$ to receive credit.

Sample Output:

$-$ Please read through this sample output carefully

$-$ Your output must match my sample output exactly for full credit $-$ including line spacing

$-$ If no error checking is shown for a particular menu option, then it is not necessary to include it for this assignment. Welcome to Mutual Fund InvestorTrack $($TM$)!$
