2. This is a continuation of Exercise 2 from Week 5 practical exercises. Use the two java files, Expenses.java and ExpensesDemo.java that you developed in Exercise 1 Week 5. Import the two java files into your week 6 project in Eclipse then: a. Add the following data field to the Expenses class Month - the name of the month for the expenses (a string] b. Add accessor and mutator methods for this new data field to the Expenses class C. Add a constructor to the Expenses class that takes a single argument (the name of the month) and sets all other data fields to 0 d. In the expensesDemo source code add Java code to do the following: i. Obtain the name of the month for which expenses will be entered, instantiate an Expenses object (using the constructor you created in part c) for the month; enter sales and expenses data for each week of the month; display the month name, balance, the total of income, total of expenditure, and Keleven from the month's expense object. ii. Set up a loop so that multiple months data may be entered by the user (the following screen shot is an example execution of the program to assist your understanding of requirements). Note: for the purpose of this question there is no need to remember' all Expenses objects that are created, hence, an array is not needed.
