Queens College Computer Science Department CS 212 – Spring 2020 – Project 4 Assigned: 23 April 2020 Due: 8 May 2020 Cutoff: 13 May 2020 (midnight; no exceptions) Use a TreeMap to Sort the Clocks The project should work the same as project 3, opening a chosen file and displaying the unsorted clocks on the left and the sorted clocks on the right. For this project do not use a sorted linked list to sort the clocks, but rather use a TreeMap (adapt the code from the PowerPoint on Maps). Create an Edit Menu in your GUI Add a second menu to the GUI called Edit which will have one menu item called Search. Clicking on search should prompt the user using a JOptionPane input dialog to enter hours for a clock. Your program should check that the hours are between 0 and 23, and that the value entered is an integer. The GUI should then display only clocks with hours at or below the given value. You will need to write a second menu handler called EditMenuHandler. Create a jar file called Project4.jar containing the source code for all the necessary classes and submit that to Blackboard by the due date for full credit.

File account. java (see previous exercise) contains a definition for a simple bank account class with methods to withdraw, deposit, get the balance and account number, and return a string representation. note that the constructor for this class creates a random account number. save this class to your directory and study it to see how it works. then write the following additional code: 1. suppose the bank wants to keep track of how many accounts exist. a. declare a private static integer variable numaccounts to hold this value. like all instance and static variables, it will be initialized (to 0, since it’s an int) automatically. b. add code to the constructor to increment this variable every time an account is created. c. add a static method getnumaccounts that returns the total number of accounts. think about why this method should be static - its information is not related to any particular account. d. file testaccounts1.java contains a simple program that creates the specified number of bank accounts then uses the getnumaccounts method to find how many accounts were created. save it to your directory, then use it to test your modified account class.
