- write a discount system for a beauty saloon using java program, which provides services and sells beauty products. It offers 3 types of memberships: Premium, Gold and Silver. Premium, gold and silver members receive a discount of 20%, 15%, and 10%, respectively, for all services provided. Customers without membership receive no discount. All members receives a flat 10% discount on products purchased (this might change in future). Your system shall consist of three classes: Customer, Discount and Visit, as shown in the class diagram. It shall compute the total bill if a customer purchases $x of products and $y of services, for a visit. Also write a test program to exercise all the classes. Don’t forget to use array customer name and member type.Write Java classes to solve the following problem: A company has two types of employees. These are called Exempt and NonExempt. Exempt means the employee is not eligible for overtime pay and is paid a fixed amount each pay period. NonExempt means the employee is paid by the hour and receives 1.5 times the hourly rate for hours worked over 40. Each Employee has an id number which is a string. They also have a name. Employee should be an abstract class with the member variables described in number 2. Employee should have an abstract method called findPay, a toString method, and it should implement the Comparable interface. Use alphabetical order of id number to determine less than, greater than, and equal to. The toString method should produce a string like the following: Emp: ID: 4590 Emp Name: Fred Jones Employee should have an equals method. Define two employees to be equal if they have the same name and the same id number. Provide accessor and mutators for Employee. NonExempt should…In Java Write a program that asks the user to enter how many automobiles are to bedescribed, and for each automobile, it (the driver) inputs the user’s selection ofmake and color. Then the driver outputs color and make. Although you could dothis easily using a simple procedural program, do it by using a main method inclass AutomobileDriver to instantiate an object called auto from a classAutomobile. Make your classes conform to the following UML class diagram:Let Automobile methods setMake and setColor do the prompting and inputtingfor make and color, and include input verification which asks again if a selectionis illegal. Let Automobile methods printColor and printMake print color andmake on one line. In AutomobileDriver, after asking auto to call setMake andsetColor, use auto.printColor().printMake(); to chain the two printing methods.Write code so that the program can produce the following display: Sample session:How many cars do you want to consider? 2 Select Buick, Chevrolet,…
- Write a JAVA program to model the kinds of people one finds in a university. The categories are students, teachers and teaching assistant (TAs). All these categories are kinds of Person (Person is abstract class. A teaching assistant (TA) is a student and a teacher as well. A person has a name (string). A student has grade point average GPA (between 0 to 4), the teacher has the number of scholarly papers he/she has published and the teacher assistant has the number of courses he/she assists. All the classes contain constructors with default arguments to fill all data spaces. Provide display method to print all data members of an object on the screen. Classes also contain a function called isSuccessful(). Students with a GPA over 3.5 are considered successful. This function returns true if someone is successful or false if not. In main(), define an array of Person class, which can point to students, teachers and teacher assistants. The program first asks the kind of person and then lets…using Java Write a grading program for a class with the following grading policies:1. There are two quizzes, each graded on the basis of 10 points.2. There is one midterm exam and one final exam, each graded on the basis of 100 points.3. The final exam counts for 50% of the grade, the midterm counts for 25%, and two quizzes each count for 12.5%. (Do not forget to normalize the quiz scores. They should be converted to a percent before they are averaged in.)Any grades of 90 or more is an A, any grades of 80 or more (but less than 90) is a B, any grades of 70 or more (but less than 80) is a C, any grades of 60 or more (but less than 70) is a D, and any grades below 60 is an F.The program will read in students’ scores from an input file named “input.txt” and output the students’ records to a file named “output.txt”, which consist of student’s ID, name, two quizzes and two exam scores as well as the students’ average score for the course and final letter grade. Define and use a class for a…Note: write a Java Program given below Create a time class that accepts hours, minutes and seconds. Define appropriate getter/setter methods.

- Consider the following design for a Product class that keep track of product inventory: public class Product { public Product(String name, double qty){} public double getQty(){} public void reduce(double qty){} public void increase(double qty){} private String prodName; private double qtyOnHand; /* Data */ } Write the code for a main() method that models the following: A grocer starts the day with 50 Hard Rolls and 25 Soft Rolls. She sells 20 Hard Rolls and 10 Soft Rolls. The next morning about half of the Soft Rolls have turned into Hard Rolls. A shipment of 50 Soft Rolls comes in. She sells 30 Soft Rolls and 20 Hard Rolls. The storeowner wants a printout telling how many of each product she now has on hand.Write a simple cash register class. (Use Java) Each cash register should keep track of the number of items checked out and the total cash in the register. We are only concerned with the number of items to check out and their prices. No need to handle item names, SKUs, taxes, etc... It should have the following methods (use static when appropriate): checkout( ) Takes two forms. If there is only one parameter that is the cash received and there is only one item checked out. If it has two parameters, the first parameter should have the number of items checked out and the second parameter is the price per item. cashout( ) Reset the number of items and total cash to zero for a cash register getItems( ) Returns the number of items in the cash register getTotalCash( ) Returns the total cash in the cash register getAveragePricePerItem( ) Returns the average price per item checked out by the cash register getRegisterCount( ) Returns the number of cash registers created getAllItems(…JAVA Write a class that corrects a sentence. Your class must capitalize the letter in each sentence. Example: Inputafter a train crashed, every single person died. who survived?all of the couples.

- IN C++ Implement a class Car with the following properties. A car has a certain fuel efficiency (measured in miles/gallon or liters/km—pick one) and a certain amount of fuel in the gas tank. The efficiency is specified in the constructor, and the initial fuel level is 0. Provide another parameterized constructor which takes both efficiency and fuel as parameters. Also supply methods getGasInTank, returning the current amount of gasoline in the fuel tank. getEfficiency() return the efficiency of car. setGasInTank(double fuel), to add gasoline to the fuel tank. setEfficiency(double efficiency) Supply a method Drive () that simulates driving the car for a certain distance, reducing the amount of gasoline in the fuel tank according to its efficiency. Sample usage: Car myHybrid (50); // 50 miles per gallon myHybrid.addGas(20); // Tank 20 gallons myHybrid.Drive(100); // Drive 100 miles double gasLeft = myHybrid.getGasInTank(); // Get gas remaining in tank Supply a main method that tests…In this exercise, you have to calculate the student's total marks using the concept of Classes Problem Statement# Write a Java class called Student with ● private fields: ○ name(String type) ○ mark1 and mark2 (double type) And methods: ● getMarks(int markNumber), a method which should return mark1 if markNumber equals 1 and mark2 otherwise. ● calcTotal() method should take the two marks entered and return their sum. Also define two constructors: ● A default constructor that takes no parameters and initializes the values to zeros and null. ● A constructor that takes the three variables and sets them as the values of the appropriate fields. Input# Name of the student and the marks obtained in the first and second tests Output# Sum of both marks Sample Input# Student student = new Student("Jack", 60, 70); Sample Output# getMarks(1) => 60 getMarks(2) => 70 calcTotal() => 130.0 Part of solution class Student { // Define private fields here public Student() { // Write…Write the classes for the Java program to run as the sample below Data: Occupation,Number of workers,Location quotient,Mean Hourly Wage,Mean Annual WageComputer systems analysts,15450,1.6,60.27,125350Information security analysts,2590,1.1,65.82,136910Computer and information research scientists,2330,4.6,78.53,163330Computer network support specialists,2840,0.9,42.8,89020Computer user support specialists,15640,1.5,37.82,78670Computer network architects,4550,1.7,71.27,148250Network and computer systems administrators,6700,1.2,51.3,106700Database administrators and architects,3830,1.7,55.16,114730Computer programmers,5690,1.9,60.3,125420Software developers and software quality assurance analysts and testers,64310,2.6,69.59,144740Web developers and digital interface designers,5990,2.3,54.76,113910Computer occupations (all other),21270,3.5,60.33,125480Actuaries,380,1,53.12,110500Mathematicians,50,1.1,65.38,135980Operations research…
