Data structure & Algorithum java program
Write a class name month. 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.

Complete #13. Dependent #1 Employee and ProductionWorker classes showing below. Modify the Employee and ProductionWorker classes so they throw exceptions when the following errors occur:
The Employee class should throw an exception named InvalidEmployeeNumber when it receives an employee number that is less than 0 or greater than 9999.
The ProductionWorker class should throw an exception named InvalidShift when it receives an invalid shift.
The ProductionWorker class should throw an exception named InvalidPayRate when it receives a negative number for the hourly pay rate.
Write a driver program that demonstrates how each of these exception conditions works.

Write a program that prompts the user to enter a person's date of birth in numeric form such as 8-27-1980. The program then outputs the date of birth in the form: August 27, 1980. Your program must contain at least two exception classes: invalidDay and invalidMonth. If the user enters an invalid value for day, then the program should throw and catch an invalidDay object. Similar conventions for the invalid values of month and year. (Note that your program must handle a leap year.)

- ArgumentException is an existing class that derives from Exception; you use it when one or more of a method’s arguments do not fall within an expected range. Write a C# application SwimmingWaterTemperature containing a variable that can hold a temperature expressed in degrees Fahrenheit. Within the class, create a method that accepts a parameter for a water temperature and returns true or false, indicating whether the water temperature is between 70 and 85 degrees and thus comfortable for swimming. If the temperature is not between 32 and 212 (the freezing and boiling points of water), it is invalid, and the method should throw an ArgumentException. In the Main() method, continuously prompt the user for data temperature, pass it to the method, and then display the following messages indicating whether the temperature is comfortable, not comfortable, or invalid: X degrees is comfortable for swimming. X degrees is not comfortable for swimming.

Complete these tasks: a. Create a FractionException class. The class contains a Fraction object and a string message explaining the reason for the exception. Include a constructor that requires values for the Fraction and the message. Also include a function that displays the message. b. Modify each Fraction class constructor and data entry function so that it throws a FractionException whenever a client attempts to instantiate a Fraction with a zero denominator. c. Write a main()function that asks the user to enter values for four Fractions. If the user attempts to create a Fraction with a zero denominator, catch the exception, display a message, and force the Fraction to 0 / 1. Display the four Fraction objects.
