OBJECT-ORIENTED SOFTWARE ANALYSIS And DESIGN (uml+c#)

(a)Definition of class Vehicle Instance variables: year                 that holds the year of vehicle (int) make               that holds the make of vehicle (string)   Methods: a second constructor that accepts the Vehicle's year and the make as arguments. These values should be assigned to the object's instance variables: year and make.  Accessor methods (getYear() and getMake()) that get the values of instance variables Mutator methods (setYear(int) and setMake(String)) that set the values of instance variables. toString() should return a string with the values of instance variables of vehicle object  equals() should accept a vehicle object reference as argument and return true if all instance variables of calling object are same values as those of passed vehicle object, respectively, or false otherwise.   brake() should do nothing (i.e., empty body). This method is for polymorphism to call appropriate brake() method of subclass.   (b)Definition of class Car, which is a…

True or False A class can implement more than one interface.

QUESTION 5 All methods in an abstract class must also be declared abstract. True False QUESTION 6 All fields declared in an interface are treated as final and static have protected access must be initialized in the class implementing the interface have private access

Declare an interface named Employee with the methods named sALARY and bEHAVIOR declarea concrete class which will implements the methods of Employee (using java)

Object-Oriented Programming Create a Java program that has the following: Inheritance -  Create a superclass and one or more subclasses that inherit properties and methods from the superclass.  Polymorphism - Show polymorphism by using method overriding and method overloading.  Provide an example of runtime polymorphism by creating objects of the subclasses and calling overridden methods. Encapsulation -  Demonstrate the concept of encapsulation by applying access modifiers (private, protected, public) appropriately in your program. Abstraction - Utilize abstract classes and methods in your program to illustrate abstraction.  Show examples of the following  words: super, this, static, final    (NO USE OF AI)

T/F 3. Any Java class must have a main method, which is the first method that is called when the Java class is invoked.

1- void 2- private 3- static 4- public Which is correct in Java
