- Create an Employee Class that will have Two instance variable: name and workingPeriod A class method named employeeByJoiningYear(): • To create an Employee object by joining year for calculating the working period o it will have two Parameter name and year • A static method experienceCheck() to check if an Employee is experienced or not o It will take working period and gender as parameter o If an employee's working period is less than 3, he or she is not experienced [You are not allowed to change the code below] # Write your code here employee1 = Employee('Dororo', 3) employee2 = Employee.employeeByJoiningYear('Harry', 2016) 6 print(employee1.workingPeriod) print(employee2.workingPeriod) print(employee1.name) print(employee2.name) print(Employee.experienceCheck(2, "male")) print(Employee.experienceCheck(3, "female")) Оutput 3 Dororo Harry He is not experienced She is experiencedCreate class employee with properties ID, name, salary, write accessor, mutator &constructor for the class. In main create three objects of class & find the employee with the highestsalary.Design a class named Employee. The class should keep the following information infields:• Employee name• Employee number in the format XXX-L, where each X is a digit within the range0-9 and the Lis aletter within the range A-M.• Hire date* Write one or more constructors and the appropriate accessor and mutator methods for theclass.Next, write a class named ProductionWorker that extends the Employee class. TheProductionWorker class should have fields to hold the following information:• Shift (an integer)• Hourly pay rate (a double)The workday is divided into two shifts: day and night. The shift field will be an integer valuerepresenting the shift that the employee works. The day shift is shift 1 and the night shift isshift 2. Write one or more constructors and the appropriate accessor and mutator methodsfor the class. Demonstrate the classes by writing a program that uses a ProductionWorkerobject. have to use beginner code because this is an intro class.
- JAVA Part One: The Member Class Write the class to represent a member. Include the following components: a constant to represent the current year of 2023 instance data variables: a name the year the member joined (stored as an int) whether or not the member is a VIP a constructor that sets all of the instance data variables using parameters getter and setter methods in your setter for the year, use validity checking to make sure the parameter is valid before assigning it to the instance data variable a toString method include the name and year joined in the text representation if the member is a VIP, include that in the text as well you can see my example of the formatting in the sample output below (note that I used tabs in my formatting) You should iteratively write, compile, and test each of these components while writing your class to make sure each works before moving on. Part Two: Class Method Write a method that determines whether a member is a "founding…Step 1. Start the programStep 2. Create a class student which contains primitive data members.Step 3: Define a constructor to initialize the data members.Step 4: Define the methods get and display to get and display the data members.Step 5: Create object for the class to access the member functions.Step 6: Display the resultStep 7: Stop the program.Calculate the grade book;Question 1: Create a class Mobile, declare its variables for mobile specs (i.e brand, color, camera) and initialized constructor. Provide set, get and display methods for each instance variable. Now create several mobile objects in main class to call these functions. Question 2: Write a program to create a room class, the attributes of this class is roomno, roomtype, roomarea and ACmachine. In this class the member functions are getdata, setdata and displaydata. Now create several objects in main class to call these functions.
- Construct a Time class containing integer data members seconds, minutes, and hours. Have the class contain two constructors: The first should be a default constructor having the prototype Time(int, int, int), which uses default values of 0 for each data member. The second constructor should accept a long integer representing a total number of seconds and disassemble the long integer into hours, minutes, and seconds. The final member method should display the class data members.1. Part 1: A point in the x-y plane is represented by its x-coordinate and y-coordinate. Design the class Point that can store and process a point in the x-y plane. Your class should contains the following methods. Default constructor without parameters that initializes the private data member to the suitable values Constructor with parameters sets the values of the instance variables to the values of the parameter. Accessor methods that return the values of the x-axis and y-axis. setPoint method which set the values of x-axis and y-axis makeCopy method that make a copy of a received object of type Point. getCopy method that returns a copy of the current object toString method that returns the object string isEqual that returns true if the current object is equal to the received object of type point distance, which receives two objects of type Point and returns the distanceObject-oriented programming Create a class called Triangle that models triangles using three points (the vertices) for the x's and three points for the y's. The vertices will be of type double. It will have two constructors: one by default and one that creates a triangle from its three vertices. The class will also include a method to calculate the area and another to calculate the perimeter of the triangle. Attributes are of type public. Write here the class diagram and class code in Java
- Temp Class - Create Temp class whos job is to hold a temp in degrees F and gives methods to get the temp in F, Celsius, and Kelvin. The class should follow the instance variable (field): ftemp (double type that holds F temp)Follow these methods with the class.. Constructor --Will accept Fahrenheit temperature as a double to store it in the ftemp field. setFahrenheit - The setFahrenheit method accepts a Ftemperature as a doubleto stores it in the ftemp field. getFahrenheit - Returns the value of the ftemp field, as a Fahrenheit temperature (no conversion required). getCelsius - Returns the value of the ftemp field converted to Celsius. [C e l s i u s = ( 5.0 / 9.0 ) × ( F a h r e n h e i t − 32 )] getKelvin - Returns the value of the ftemp field converted to Kelvin. [K e l v i n = ( ( 5.0 / 9.0 ) × ( F a h r e n h e i t − 32 ) ) + 273] Exemplify the temp class by writing a (test) program that is separate and promotes users for an F Fahrenheit temp. The program must create an…Design a Ship class that has the following members: • A member variable for the name of the ship (a string) • A member variable for the year that the ship was built (a string) • A default and parameterized constructor and appropriate getters and setters. • A toString method that displays the ship’s name and the year it was built. Design a CruiseShip class that is derived from the Ship class. The CruiseShip class should have the following members: • A member variable for the maximum number of passengers (an int) • A default and parameterized constructor and appropriate getters and setters. • A toString method that overrides the toString function in the base class. The CruiseShip class’s toString function should display only the ship’s name and the maximum number of passengers. Design a CargoShip class that is derived from the Ship class. The CargoShip class should have the following members: • A member variable for the cargo capacity in tonnage (an int). • A default and parameterized…Create an Account Object project. 1. Create an Account class and use the provided UML diagram to code the instance fields, constructors and methods. Note: The type of accounts are 1 (Savings) or 2 (Cheque) The constructor must assign the values of the parameters to the data fields/instance variables. The static field must be increased by one in the constructor. The setAccNumber() is a private void method. The account number must consist of the first 3 letters of the name of the account holder, the digit indicating the type of account and #-character and a 3-digit random value. This method must be called from the constructor. The makeDeposit() method must add the amount received as a parameter to the balance if the value received is not a negative value. The withdrawAmount() method must check whether the balance allows for the amount to be withdrawn. There must always be a minimum amount of R 100.00 in an account. If there is not enough money in the account to do the transaction,…
