Chapter 6, Problem 9PC
Days in a Month
Write a class named MonthDays, The class’s constructor should accept two arguments:
- An integer for the month (1 = January, 2 February, etc.).
- An integer for the year
The class should have a method named numberOfDays that returns the number of days in the specified month. The method should use the following criteria to identify leap years:
- 1. Determine whether the year is divisible by 100. If it is, then it is a leap year if and if only it is divisible by 400. For example, 2000 is a leap year but 2100 is not.
- 2. If the year is not divisible by 100, then it is a leap year if and if only it is divisible by 4. For example, 2008 is a leap year but 2009 is not.
Demonstrate the class in a
Enter a month (1-12): 2 [Enter]

Month Class Exceptions
Write a class named Month. The class should have an int field named monthNumber that holds the number of the month. For example, Janauary would be 1, February would be 2, and so forth.
In addition, provide the following methods:
A no-arg constructor that sets the monthNumber field to 1.
A constructor that accepts the number of the month as an argument. It should set the monthNumber value to the value passed as the argument. If a value less than 1 or greater than 12 is passed, the constructor should throw an InvalidMonthNumberException.
A constructor that accepts the name of the month, such as “January” or “February”, as an argument. It should set the monthNumber field to the correct corresponding value. If an invalid name is passed, the constructor should throw an InvalidMonthNameException.
A setMonthNumber method that accepts an int argument, which is assigned to the monthNumber field. If a value less than 1 or greater than 12 is passed, throw an…

Assignment Description:
Write a class named Car that has the following fields:
The yearModel field is an int that holds the car’s year model.
The make field references a String object that holds the make of the car.
The speed field is an int that holds the car’s current speed.
In addition, the class should have the following constructor and other methods.
The constructor should accept the car’s year and make as arguments. These values should be assigned to the object’s yearModel and make fields. The constructor should also assign 0 to the speed field.
Constructor: The constructor should accept no arguments.
Constructor: The constructor should accept the car’s year as argument.Assign the value to the object’s yearModel. No need to assign anything to the make and assign 0 to speed.
Appropriate mutator methods should set the values in an object’s yearModel, make, and speed fields.
Appropriate accessor methods should get the values stored in an object’s yearModel, make, and…

- Assignment: Dice Rolling Program Objective: Create a Java program that rolls two dice and displays the results. The program should have two Java classes: one for a single die and another for a pair of dice. Assignment Details: User Input: Ask the user to specify the number of sides they want on each die. Ensure that the user's input is within a reasonable range. Dice Rolling: Simulate rolling the dice using Math.random() based on the user's chosen number of sides. Display the sum of the values rolled, e.g., "5 + 3 = 8." Special Combinations: If the dice roll results in combinations of 2, 7, or 12, print special messages: "1 + 1 = 2 snake eyes!" "3 + 4 = 7 craps!" "6 + 6 = 12 box cars!" Main Method: In the main method, create a pair of dice, roll them, and display the results. Allow the user to decide whether to continue rolling the dice or exit the program. Additional Features: You are welcome to add more features or enhancements to the program if desired.

- The program must include two classesclGradesGraph and GradesGrapghDemo. GradesGraphDemo (one method)- Main method only GradesGraph- Include at least 4 methods (No credits without at least 4 methods!!!) Create a class that represents the grade distribution for a given course. In this class you should write methods to perform the following tasks: Read the number of each of the letter grades A, B, C D and F Set the number of letter grades A, B, C, D and F Return the total number of grades Return the percentage of each letter grade as a whole number between 0 and 100 inclusive Draw a bar graph of the grade distributionThe graph should have five bars, one per grade. Each bar can be a horizontal row of asterisks, such that the number of asterisks in a row is proportionate to the percentage of grades in each category. For example, let on asterisk represent 2%, so 50 asterisks correspond to 100%. Mark the horizontal axis at 10% increments from 0 to 100% and label each line with a letter…arrow_forwardCargo Ships This question involves cargo ships that carry a specific number of cargo containers. Each ship has a maximum number of cargo containers that it can hold and a current number of cargo containers that it is holding. You can see more details in the Ship class that is provided for you. Part A For part A, you will be completing the nextToUnload() method. This takes no input and returns a Ship from the ships instance variable that has the highest percentage of its cargo hold filled (as measured by current hold / capacity). If two ships have the same percentage, then it should return the first ship with that percentage. If all of the ships in the ships array are empty (ie. no cargo), the method should return null. Part B For part B, you will complete the two unloadShip methods. The first method takes a Ship object and unloads all of the cargo from that ship. The second method takes a Ship and an int and unloads the specified number of containers from the ship. If the number of…arrow_forwardQuestionarrow_forward
