This exercise guides you through the process of modifying the Future Value application so it uses classes that provide static methods. 1. Open the project named ch07_ex2_Future Value that's stored in the ex starts directory. Then, review the code for the Future ValueApp class.
2. Start a new class named Console in the same package as the FutureValueApn class. Then, move the getDouble(), getDoubleWithinRange(), getInt(), and getIntWithinRange() methods from the Future ValueApp class to the Console class. For this to work, you will also need to add an import statement for the Scanner class to the Console class.
3. Change the name of the getDoubleWithinRange() method to getDouble(), and change the name of the getIntWithinRange() method to getInt(). This overloads the getDouble() and getInt() methods.
4. Modify the Future ValueApp class Then, run the application to make sure it still works correctly.
5. Start a new class named FinancialCalculations in the same package as the other classes. Then, move the calculateFuture Value() method from the Future ValueApp class to the FinancialCalculations class, and make sure that the method is public
6. Modify the Future ValueApp class so it uses the static calculateFuture Value) method that's stored in the Financial Calculations class. Then, run the application to make sure that it still works properly.
