Assume that we have four classes: Person, Teacher, Student, and PhDStudent. Teacherand Student are both subclasses of Person. PhDStudent is a subclass of Student.A.Which of the following assignments are legal, and why or why not?Person p1 = new Student();Person p2 = new PhDStudent();PhDStudent phd1 = new Student();Teacher t1 = new Person();Student s1 = new PhDStudent();Suppose that we have the following legal declarations and assignments:Person p1 = new Person();Person p2 = new Person();PhDStudent phd1 = new PhDStudent();Teacher t1 = new Teacher();Student s1 = new Student();B.Based on those just mentioned, which of the following assignments arelegal, and why or why not?s1 = p1;s1 = p2;p1 = s1;t1 = s1;s1 = phd1;phd1 = s1;
An employee has a name, phone number and salary. A coach is a person with a senitority status, one of: junior, lead, and senior. Define the possible status values as constants. A staff is a person with a job title and job descrption. Your programming task is to Implement as abstract class named Employee and two subclass name Coach and Staff in Java as defined above Provide constructors for classes to initalize private variable Override the toString() method in each of the classes in task 1 to display the class name and the person's name Write an application to create objects of type Coach and Staff and print the person's name and the class name of the objects
Suppose class A inherits from class B which has a subclass C, and class D inherits from C. Answer the following: 1- What is the order of "calling (invoking) constructors" when an object of class A is instantiated? 2- What is the order of "calling (invoking) constructors" when an object of class D is instantiated? The question asks about constructor invocation and not the execution of the constructor body. Please be aware For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).
Partial Question 3 Consider: class A { } public void doA() { } class B extends A { } public void doB () { } Which of the following are allowed? B x = new B(); x.doB(); A x = new A(); x.doA(); A x = new A(); x.doB(); B x = new B(); x.doA();
Given the following definitions: public abstract class Manager extends Employee {...} public class Executive extends Manager { ... } What, if anything, is wrong with the following code? public class hrSystem { } public void payRaise () { } Manager m = new Manager(); O Compiler error because there is no Manager constructor. Compiler error because Manager is abstract so an instance cannot be created. No problem. The code will compile without any errors. O Compiles fine but will generate a run-time error unless an Employee object is created first.
Design a class named LinearEquation for a 2 × 2 system of linear equations: The class contains: ax + by = e cx + dy = f ■ Xx= ed - bf ad - bc y = af - ec ad – bc Private data fields a, b, c, d, e, and £. ▪ A constructor with the arguments for a, b, c, d, e, and f. ▪ Six getter methods for a, b, c, d, e, and f. ▪ A method named isSolvable () that returns true if ad – be is not 0. ▪ Methods getX() and getY() that return the solution for the equation. Draw the UML diagram for the class then implement the class. Write a test program that prompts the user to enter a, b, c, d, e, and f and displays the result. If ad - bc is 0, report that "The equation has no solution."
