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:
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.
Step by step
Solved in 2 steps
- Assume that you have created a class named MyClass. The header of the MyClass constructor can be ____________. public MyClass() public MyClass (double d) Either of these can be the constructor header. Neither of these can be the constructor header.Java - If the programmer doesn't declare any constructors for an extended class, what constructors will be inherited from the superclass? How does this inherited constructor initialize new instance variables that are not part of the superclass?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.
- This task helps you understand how constructors work in inheritance Create a superclass, called SuperClass. Create a constructor for it. Inside the constructor, let it print “this is super class.” Create a childclass of SuperClass, called ChildClass. Create a constructor for it. Inside the constructor, let it print “this is child class.” Create a main function and create a new object for ChildClass. Observe what’s printed in console. What will happen if you have a default constructor without parameters in addition to the one with parameters?Object Oriented Programming (Java): True or False Statements with one line reasoning: 1. The implementation of inheritance always involves writing a few less lines. 2. The following class declaration is incorrect: public final class Class extends OtherClass {...} 3. Inheritance is only useful if specialization is used. In fact, specializing we inherit in the subclass (or subclasses) members of the superclass that we must not rewrite. Instead with the generalization we create an extra class, and then we write more code. 4. The super keyword allows you to call superclass methods and constructors. The keyword this allows you to call methods and constructors of the same class. 5. Multiple inheritance does not exist in Java because it does not exist in reality.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)
- True or False A subclass can have more fields and methods than its superclass.C++ Exercise 2 (inheritance):Consider a circle class that has a single attribute R (radius).1. Write a program that allows you to create this class that contains:o A single attribute.o A default constructor that initializes R to 1.o A parameterized constructor.2. Create another cylinder class that inherits the circle class publicly. Theclass cylinder contains:o A single H (Height) attribute.o A parameterized constructor.o A member function to calculate and display the volume of the cylinder.Create abstract class Pet , which is the abstract superclass of all animals. Declare a integer attribute called legs, which records the number of legs for this animal. Define a constructor that initializes the legs attribute. Declare an abstract method eat. Declare a concrete method walk that prints out something about how the animals walks (include the number of legs). Create the Dog class. The Dog class extends the Pet class. This class must include a String attribute to store the name and food of the pet Define a default constructor that calls the superclass constructor to specify that all dogs have 4 legs and name. override the eat and walk method. Create the Cat class that extends Pet. This class must include a String attribute to store the name of the pet, and a string to save food . Define a constructor that takes one String parameter that specifies the cat's name and food. This constructor must also call the superclass constructor to specify that all cats have four legs.…

A food is described by a name, the number of grams of sugar (as a whole number), and the number of grams of sodium (as a whole number). Core Class Components For the Food class, write: the complete class header the instance data variables a constructor that sets the instance data variables based on parameters getters and setters; use validity checking on the parameters where appropriate a toString method that returns a text representation of a Food object that includes all three characteristics of the food Class-Specific Method Write a method that calculates what percent of the daily recommended amount of sugar is contained in a food. The daily recommended amount might change, so the method takes in the daily allowance and then calculates the percentage. For example, let's say a food had 6 grams of sugar. If the daily allowance was 24 grams, the percent would be 0.25. For that same food, if the daily allowance was 36 grams, the…employee and production worker classes write an employee class that keeps data attributes for the following pieces of information: • employee name • employee number next, write a class named productionworker that is a subclass of the employee class. the productionworker class should keep data attributes for the following information: • shift number (an integer, such as 1, 2, or 3) • hourly pay rate the workday is divided into two shifts: day and night. the shift attribute will hold an integer value representing the shift that the employee works. the day shift is shift 1 and the night shift is shift 2. write the appropriate accessor and mutator methods for each class. once you have written the classes, write a program that creates an object of the productionworker class and prompts the user to enter data for each of the object’s data attributes. store the data in the object, then use the object’s accessor methods to retrieve it and display it on the screen. satak overfallow
