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:
Every attribute and method declared in a class has an access modifier such as private, public
and protected. Differentiate each of them.
Step by step
Solved in 2 steps
- The technique of packaging an objects attributes into a cohesive unit that can be used as an undivided entity is ____________. a. inheritance b. encapsulation c. polymorphism d. interfacingAn access modifier, such as private or public, is assigned to each and every property and method that is specified in a class. as well as safeguarded Make a distinction between each of them.In order to extend a class, the new class should have access to all the data and inner workings of the parent class. True False
- Problem: Course information System Super Class Attributes Methods : Student Studentid, StudentName, Address, Level Set the student details using constructor Display the Student details Sub class : Course Attributes Methods Coures1, Course2, Credit1, Credit 2, Mark1, Mark2 Set the course details using constructor Calculate the total number of credits Calculate the total number of marks Display the course details Driver Class : Display the student details and course details. The following information are required for the assignment Properties with proper data types Methods with proper return types and scope Demonstration of OOP feature- (Inheritance) Demonstration of user defined package Proper naming convention Proper comments in each program and within program Purpose of each code should be explained. Program Execution (output) Presentation (Word Document) 56S1740Protection against the accidental modification of class fields is essential.Problem: Employee personal Information system Super Class : Personal Attributes : Methods Name, Age, Address, Phone number Set the personal details values Display the personal details Sub class : Employee Attributes : employeeid, department, salary Methods : Set the values of employeeid, department, salary Calculate the Gross_Salary and retun the gross salary Display the employee details Driver Class : • Display the personal details and employee details. The following information are required for the assignment Properties with proper data types Methods with proper return types and scope Demonstration of OOP feature (Inheritance) Demonstration of user defined package Proper naming convention Proper comments in each program and within program Purpose of each code should be explained. Program Execution (output) Presentation (Word Document) 56S17108
- Class members may be declared as... overloaded private or public attributes constructorsSuper Class : Employee Attributes : Employee_id name, salary Methods : • Read the employee details • Display the employee details Sub class : Salary_details Attributes : HRA,CCA,DA,Gross_salary Methods : • Calculate the HRA, DA,CCA • Calculate the Gross_Salary and return the gross salary • Display the salary details. Driver Class : • Display the employee details and salary details. The following information are required for the assignment Properties with proper data types Methods with proper return types and scope Demonstration of OOP feature (Inheritance) Demonstration of OOP feature (polymorphism) Proper naming convention Proper comments in each program and within program Purpose of each code should be explained. Program Execution (output) Presentation (Word Document)Explain the difference between the private and protected members of a class.
- Library Information System Design and Testing Library Item Class Design and TestingDesign a class that holds the Library Item Information, with item name, author, publisher. Write appropriate accessor and mutator methods. Also, write a tester program(Console and GUI Program) that creates three instances/objects of the Library Items class. Extending Library Item Class Library and Book Classes: Extend the Library Item class in (1) with a Book class with data attributes for a book’s title, author, publisher and an additional attributes as number of pages, and a Boolean data attribute indicating whether there is both hard copy as well as eBook version of the book. Demonstrate Book Class in a Tester Program (Console and GUI Program) with an object of Book class.The properties of a child class are inherited by the parent class. Select one: True FalseIf a class is only ever instantiated as part of the constructor of another class, what is the most specific relationship that exists between them? Association Aggregation Composition Inheritance / Generalization
