- Microsoft Visual C# 7th edition. In Chapter 7, you modified the GreenvilleRevenue program to include a number of methods. Now, using your code from Chapter 7 Case Study 1, modify your program so every data entry statement uses a TryParse() method to ensure that each piece of data is the correct type. Any invalid user entries should generate an appropriate message that contains the word Invalid, and the user should be required to reenter the data. I am working in CENGAGE MINDTAP. Here is my code, but the TryParse is not working.

The class should have an int field named monthNumber that holds the number of the month. For example, January would be 1, February would be 2, etc. The class should also have appropriate constructors and getter / setter methods. There should also be a getMonthName that returns the name of the month corressponding to the month number. Also include exception code when a number less than 1 or greater than 12 is given in the constructor and/ or the set method. Demonstrate the classess and catching the exception in a program, such as Month Test. Display appropriate information to the user if an erro occurs.arrow_forwardTo write an application that uses recursion to solve a problem. Details: Create a class called Power that computes the value of base exponent. The class should have one recursive method: • public static int power(int base, int exponent) – Which computes the value of base exponent using recursion, returning the result. The recursion step should use the following relationship base exponent = base x base exponent - 1 and the termination condition should occur when exponent is equal to 1, because base 1 = base NOTE: For the power method, assume the exponent parameter value is always greater than 0. Create a second class called PowerTest that contains the main method, and tests the Power.power method. The test class does not need to ask for input from the user of the class, nor does it need to do any additional error checking. Upload both source files to Blackboard. Note: Ensure that your program is properly formatted and it follows all Java naming conventions.arrow_forward

Its purpose is to fill a simpy's values with a specific number of repeating values. The fill method will have two parameters following self: 1. The float value you are filling the values list in with. 2. The int number of values to fill in. The fill method is procedure-like in that it returns None and mutates the object the method is called on. After calling fill, the length of the Simpy object's values should be equal to the second argument given to fill. For example, consider the following usage and expected printed output, given inline, below: twos = Simpy([]) twos.fill(2.0, 3) print("Actual: ", twos, Expected: Simpy([2.0, 2.0, 2.0])") twos.fill(2.0, 5) print("Actual: ", twos, " - Expected: Simpy([2.0, 2.0, 2.0, 2.0, 2.0])") mixed = Simpy([]) mixed.fill(3.0, 3) - Expected: Simpy([3.0, 3.0, 3.0])") print("Actual: ", mixed, mixed.fill(2.0, 2) print("Actual: ", mixed, Expected: Simpy ([2.0, 2.0])") Pythonarrow_forward
