OOPs

In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.

Constructor

The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

Question

Given
class x{
static int a;
int b=12;
void m1(0){ }
static void m2(){ }
}
class Ab extends x{
static int a;
int b=10;
void m10{ }
static void m20){ }
public static void main (String[] args){
int b=3;
x obj=new Ab();
}
}
How can you display the contents of the variable "b" in the child
class
cast obj before getting access to it
O just use obj.b
O you cannot get access to the "b" in the child class
O use the super keyword

When a subclass method has the same name, parameter list and
return type
as a method in the parent class, the method is said to be:
extended
overriden
overloaded
overextended

variables are variables that have the same name as variables that have been declared in a superclass and are declared in a subclass, respectively.
True or False ___(7) An object can be created from an interface. ___(8) An object in a super class can be assigned to a subclass variable. ___(9) Overriding and overloading a method is the same.
What keyword is used if a subclass needs to call a method in a superclass?
When a method in a subclass overrides a method in superclass, it is still possible to call the overridden method using super keyword. If you write super.func() to call the function func(), it will call the method that was defined in the superclass. You are given a partially completed code in the editor. Modify the code so that the code prints the following text: Hello I am a motorcycle, I am a cycle with an engine. My ancestor is a cycle who is a vehicle with pedals. import java.util.*;import java.io.*; class BiCycle{String define_me(){return "a vehicle with pedals.";}} class MotorCycle extends BiCycle{String define_me(){return "a cycle with an engine.";}MotorCycle(){System.out.println("Hello I am a motorcycle, I am "+ define_me()); //////code hereString temp=define_me(); //Fix this line and code here/////code ends here System.out.println("My ancestor is a cycle who is "+ temp );}}class Solution{public static void main(String []args){MotorCycle M=new MotorCycle();}}
What methods are required to modify subclasses?
When a class implements an interface with default methods and overrides them, the class inherits the default methods’ implementations. An interface’s designer can now evolve an interface by adding new default and static methods without breaking existing code that implements the interface. State whether the statement is true or false. If false, explain why.
Assignment:  Write the class XXXX_Worker with constructors, accessors, mutuators, and a toString method. A Worker has a Worker Name and Number.  Write the class XXXX_ProductionWorker which is a subclass of Worker. The production worker has a shift number (values: 1 or 2) and an Hourly pay rate. A shift number of 1 means the day shift and 2 means the night shift.  Write the class XXXX_ShiftSupervisor which is a subclass of Worker. The shift supervisor is a salaried worker who supervises a shift. The shift supervisor has a yearly bonus field. The yearly bonus is earned at year end based on performance.  Write a class, XXXX_TestWorker, which does the following: Creates one Shift Supervisor object from information entered by the user. Creates an Array of Production Workers that can hold 3 objects. Itcreates3ProductionWorkerobjectsfrominformationenteredbytheuser Prints the information about each object in the format shown below using the toString methods of the…
Describe the rules and conditions that must be followed when overriding a method in a subclass.
True or False:Unlike other members of a superclass, constructors of a superclass are not inherited by its subclasses. This means that you must define a constructor for a class or use the default constructor added by the compiler.
Variables having the same name as variables declared in a superclass are assumed to be the same as variables specified in a subclass.
What method is automatically executed whenever a new instance of the class, which the method belongs to, has been instantiated? a. encapsulation b. abstraction c. polymorphism
Person and Customer Classes Write a class named (Person) with data attributes for a person’s name, address, and telephone number. Provide accessors/getters and mutators/setters for each attribute. Write a displayPerson() to print out the attributes of the Person. Next, write a class named (Customer) that is a subclass of the (Person) class. The (Customer) class should have a data attribute for a customer number, and a Boolean data attribute indicating whether the customer wishes to be on a mailing list. Provide accessors/getters and mutators/setters for each attribute. Write a display customer() to print out the attributes of the Customer. Demonstrate an instance of the (Customer) class in a simple program.
