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]
Enter a year: 2008 [Enter]
29 days

- C# Console Application for Minesweeper In this milestone, students will create three classes: Cell, Board, and Program. Create a class that models a game cell. A game cell should have the following properties: a.Its row and column. These should initially be set to -1. b.Its visited boolean value. This should initially be set to false. c.Live boolean value. This should initially be set to false. "Live" set to true will indicate that the cell is a "live bomb" cell. d.The number of neighbors that are "live." This should initially be set to 0. The Cell class should have a constructor, as well as getters and setters for all properties. 3.Create a class that models a game board. A game board should have the following properties: a.Size. The board will be square, where the size includes the dimensions of both the length and width of the board. b.Grid. The grid will be a 2-dimensional array of the type cell. c.Difficulty. A percentage of cells that will be set to "live" status. 4.The Board…arrow_forward#pyhton programing topic: Introduction to Method and Designing class Method overloading & Constructor overloading ------------------ please find the attached imagearrow_forwardThe code for a class, the code for a method, and the code for while and for loops with more than ones statement is enclosed in ____. /* and */ [ and ] { and }arrow_forward
- Quickly please i need help in 15 minutes please please please pleasearrow_forwardThe 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_forwardpython Cylinder class: Instance variables: Make instance variables appropriately to accomplish the tasks you need. Methods: ?_init_ :: constructor, initializes instance variables o Additional Parameters: diameter and height (in that order) o Assumption: diameter and height will always be numbers which represent measurements in millimeters o Temporary Assumption (we will fix this later): diameter will never be negative and height wilI always be positive number above o ? get_volume : returns the volume of the cylinder based on its height o Additional Parameters: No additional parameters (just self). .0 Note: Use pi from the math module ?_str__ :: returns string representation with this format: "Cylinder (radius: 20.25mm, thickness: 6.10mm, volume: 7858.32mm^3)" o Additional Parameters: No additional parameters. o Notes: ? The quotes in the example are just our string boundaries! The first character in the above example is C. ? This method reports the radius (NOT the diameter). ? All…arrow_forward
- Focus on classes, objects, methods and good programming style Your task is to create a BankAccount class. Class name BankAccount Attributes _balance float _pin integer Methods init () get_pin() check pin () deposit () withdraw () get_balance () The bank account will be protected by a 4-digit pin number (i.e. between 1000 and 9999). The pin should be generated randomly when the account object is created. The initial balance should be 0. get_pin () should return the pin. check_pin (pin) should check the argument against the saved pin and return True if it matches, False if it does not. deposit (amount) should receive the amount as the argument, add the amount to the account and return the new balance. withraw (amount) should check if the amount can be withdrawn (not more than is in the account), If so, remove the argument amount from the account and return the new balance if the transaction was successful. Return False if it was not. get_balance () should return the current balance.…arrow_forwardA special static method named is used to provide a starting point for the execution of a program using the class that declares it. *arrow_forwardFreezing and Boiling PointsThe following table lists the freezing and boiling points of several substances.Substance Freezing Point || Boiling PointEthyl Alcohol -173 || 172Oxygen -362 || -306Water 32 || 212Design a class that stores a temperature in a temperature field and has the appropriate accessor and mutator method for the field. In addition to appropriate constructors, the class should have the following methods:• isEthylFreezing. This method should return the boolean value true if the tempera-ture stored in the temperature field is at or below the freezing point of ethyl alcohol. Otherwise, the method should return false.• isEthylBoiling. This method should return the boolean value true if the tempera-ture stored in the temperature field is at or above the boiling point of ethyl alcohol. Otherwise, the method should return false.• isOxygenFreezing. This method should return the boolean value true if the tem-perature stored in the temperature field is at or below the freezing…arrow_forward

The LunchOrder application should includea Food object with a constructor that accepts the price, fat, carbs, and fiber for an item. Food methods should return the price of the item and return the fat, carbohydrates, and fiber. Use the chart below forfood prices and nutrition information:arrow_forwardLab 2 – Designing a class This lab requires you to think about the steps that take place in a program by writing pseudocode. Read the following program prior to completing the lab. Design a class named Computer that holds the make, model, and amount of memory of a computer.
