- Convert the following UML diagram into the Java code. Write constructor, mutator and accessor methods for the given class. Create an instance of the class in a main method using a Demonstration class. Note: The structure of the class can be compiled and tested without having bodies for the methods. Just be sure to put in dummy return values for methods that have a return type other than void. Exercise Log ExerciseID: integer ExerciseCategory: string TimeSpent: float Calories: floatWrite 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…JAVA CLASS AND OBJECT JAVA JAVA JAVA Write a java program/code of the given problems below: abstract class Animal { // abstract methods abstract void move(); abstract void eat(); // concrete method void label() { System.out.println("Animal's data:"); } } 1.) Modify the abstraction example code above by adding another class “TestCarabao” with the necessary methods “label, move, and eat”. 2.) Write a program that creates a car object, and displays the year and name with one method “speed”. Example output: Year: 2021 Model: Toyota Speed: 200km/h 3.)

- Write a java program as shown in the following UML class diagram:(read the details below) The classes Name and Date are separate classes used as properties in the Employee class. Class Employee is the superclass of the classes SalariedEmployee and HourlyEmployee. The superclass has the attributes name and data of hire and methods to set and get these attributes. It also has 2 abstract methods equals() which check if the objects are same and toString() which convert the properties to a printable string. Also the method read() which used as an input method. The SalariedEmployee subclass has in addition to the attributes of the super-class the attribute annualSalary and set and get methods for it. This class also defines the read() method and grossPay() which in this case returns the salary of the employee. The HourlyEmployee subclass has in addition to the attributes of the super-class, the hoursWorked and hourlyRate attributes. It provides ‘get’ and ‘set’ methods for these attributes.…Instructions: Implement the Java class Customer by following the UML class diagram provided below. Implementation details: The class constructor must receive the arguments in the following order: String firstName, String lastName, String address, String cardNumber, int pin, String username The password must be generated inside the class constructor by the class method generatePassword(). The password to be generated must meet the following criteria: Must have at least one numeric character. Must have at least one lowercase character. Must have at least one uppercase character. Must have at least one special symbol among @#$% Password length to be generated is fixed and equal to 12. Do please use SecureRandom() class to achieve randomness during password generation. toString() return value format must be as follows:Customer [firstName='John', lastName='Monkey', cardNumber='11336688', pin='1234', username='j.monkey', password='zF$7zR#1lFAo', address='453 Manin st,…in java language... Draw the UML diagram of the following class: public class Employee { String name; double salary; public Employee() { } public double getSalary() { return this.salary; } public String getName() { return this.name; } }
- Using JAVA write a code to: Implement a class Person with a name and a year of birth. Add a class Student that inherits from Person and has a major. Add a class Instructor that inherits from Person and has a salary. For each class, write the needed constructors, getters, setters, and a toString method that stringifies the instance variables in a readable format. Supply a test program that instantiates an instance of each class and exercises each method defined for the class.Below we have class diagrams with three classes for a simple java based parking management class. Use the classes below to write java code for classes :a parking observer class (that implements an observer pattern) , a transaction manager class and a parking lot class(subject to the observer). Use the class diagram and java class to implement it. You should use an observer pattern to implement your code.The main goal is to implement the following - Once a car enters (in an entry-scan only lot) or leaves (in an entry-scan and exit-scan lot), then the ParkingObserver will be updated, and then can register the charge with the parking system via the TransactionManager’s park() methodwrite 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.
