Write a program in java for the following scenario and write a Driver class to test your construction: 1. Create a class Projects which has the following members: Member Variables: • projectId //Id of the project - String type • projectMarks //marks of the project - double type Member Methods: • A parameterized constructor to initialize the instance variables. • Declare a method calcGradePoint() which returns the Grade Point for the project marks as follows: If projectMarks is >50 gradePoint = 2.5% of the projectMarks • Declare an abstract method calcGrade() which will return the grade value. If projectMarks is

Java Programming problem Create a checking account class with three attributes: account number, owner’s name, and balance. Create constructor, getters and setters. If one is to set the initial balance of an account as a negative value in a setter or a constructor, remind the user about the error and set it as 0. Create a CheckingAccountDemo class, and create a main method in which Ask for the name, account number, and initial balance for one account from the keyboard input. With these input values as arguments in a call to the constructor, create a CheckingAccount object. Print the summary of this account that includes information on the name, account number, and balance by calling the getters.
Create an Employee Class that will have ● Two instance variable: name and workingPeriod ● A class method named employeeByJoiningYear(): o 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) print(employee1.workingPeriod) print(employee2.workingPeriod) print(employee1.name) print(employee2.name) print(Employee.experienceCheck(2, "male")) print(Employee.experienceCheck(3, "female")) Output 3 5 Dororo Harry He is not experienced She is experienced

Define a class named Employee. This class should extend the Person class from the previous question. The class should have a constructor, which takes the name, age, employer (String) and salary (int) as parameters (in that order). The first two parameters should be passed to the constructor of the superclass and the value of the last two parameters should be stored in instance variables. The class should define the methods, getSalary which returns the salary of the employee and getEmployer which returns the name of the employer. Any methods from the previous question that need to be overridden should be overridden! Use super and instanceof as appropriate. I.e., for the following methods you should be able to call the method in the superclass for specific situations (e.g. the compareTo method in the superclass can be called if you receive anything other than an Employee, and this also holds for the equals method). The toString method only needs to append details and as such can also…
Programming exercise (in java eclipse , please add comment for each step)thank you Create a class called "Bird" and do the following: 1)Define two data fields, 2)Define one default constructor 3)Define one constructor that takes two arguments 4) Define one method Inside the main() method, you have to create two objects for the class "Bird" one by using default constructor and another by using the constructor that takes two arguments. Also call the instance method inside the main() method (The class data fields and method should be meaningful clearly representing the entity 'Bird' . Do not define irrelevant data fields and method.)

Write the Java code for applying the following requirement: 1. Create a class named Employee. 2. Employee class has attributes name, age, and height. Add these to the Employee class which are private access specifiers. 3. Create a constructor method with 3 parameters fname, age and hg that runs as soon as the class being instantiated. This method accepts required information and pass to Employee class variables. 4. Create a method Print_Employee_Age that prints the Employee Age whenever it is being called. 5. Create another class named Admin which is a sub-class of Employee.
Create a class Book with the data members isbn, title, price. Create a class Special Edition which is subclass of Book and with a data member discountRate. Create a class BookTest with main() to test the above classes. Constructors & Methods: - Create constructors to give the values to the data members. Values shall come from user. - Create a method display() in Book class which displays isbn, title and price. Override the same display() of Book class in Special Edition. This method displays isbn, btitle, price using super.display() and display the discounted price.

JAVA A company needs to develop an object-oriented library with a few Java classes forthe following task. Overall, they want the classes to model the geometric shapes and calculatetheir areas. These geometric shapes include Square, Rectangle, Circle, and Triangle.The above four shapes share common attributes such as name and color. The area of a shapecan be calculated by using a method area( ) which can be implemented only until the exactshape is known. Different shapes need a different area( ) method.1) Design a Java abstract class called Shape to model this situation, which will serve as a parentclass. Write its code;2). All the above shapes should be drawable by the users by calling the draw( ) method.Different shapes are drawn differently. You should design a Java interface named Drawableto provide this method for the shape classes to implement in their own ways. Write its code;3). Write the code for the four classes: Square, Rectangle, Circle, and Triangle.Note:• You should decide…
