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:
Declare an interface named Employee with the methods named sALARY and bEHAVIOR declare
a concrete class which will implements the methods of Employee (using java)
Step by step
Solved in 3 steps
- True or False A class can implement more than one interface.Java Programming Question [Problem Description]Create an Employee class with name, age, sarary and bonus. Define a constructor to initialize these attributes of the class.Define method to output the employee's name, age, and total income (the sum of salary and bonus). [Input form]Please input the employee's name:Please input the employee's age:Please input the employee's salary:Please input the employee's bonus: [Output form]Employee's name:Employee's age:Employee's income:[Input Sample ①]Please input the employee's name: TomPlease input the employee's age: 20Please input the employee's salary: 3000.0Please input the employee's bonus: 4000.0 [Output Sample ①]Employee's name: TomEmployee's age: 20Employee's income: 7000.0 [Sample explanation]The format of the input and output must exactly match the specified format, otherwise no score.JAVA code Create a Calculator class that has following methods: sum, multiply, divide , modulus , sin , cos , tan The user should be able to call these methods without creating an object of Calculator class.
- What does it mean that a method or class is abstract?A Java class can contain Variables Methods, Constructors Inner Classes (A class inside another class) O All the aboveAnswer By True or False , JAVA LANGUAGE A Java interface can contain only constants and abstract methods. A class that implements an interface can define only the methods that are included in the interface. A static variable can be referenced only from a static method. Static variables are also called class variables.
- Design/code/test a Java program containing an abstract the class absWelcome. This class should contain: 1. A public abstract void method (you name it) that is empty 2. A public regular method (you name it) that prints "Welcome to " Next, create a subclass clsHello that extends absWelcome. This class should contain: • A public regular method (you name it) that prints "Java Programming" Finally, inside the Main class create an object (you name it) from the clsHello class. Use this new object reference to: 1. Output "Welcome to " from the abstract class 2. Output "Java Programming" from the subclass Your output should resemble that shown below >sh -c javac -classpath -type f-name '*.java') java -classpath :targe Welcome to Java ProgrammingJava Programming Create "Mammal" class as a parent class and "cat" as a child class Mammal(Superclass) Attributes name Methods move() eat() cat (Subclass) Attributes age Methods dispaly() eat() Override eat method in cat subclass. Print something in methods such as in move method you can print “I can move”. Test the inheritance with creating objects and calling parent and child methods. Create object of a child class by passing arguments to the constructor.Task Performance A Simple Payroll Program Objective: At the end of the activity, the students should be able to: Create a program that exhibits inheritance and polymorphism. Software Requirements: Latest version of NetBeans IDE Java Development Kit (JDK) 8 Procedure: 1. Create four (4) Java classes. Name them RunEmployee, Employee, FullTimeEmployee, PartTimeEmployee. The RunEmployee class shall contain the main method and will be used to execute the program. 2. Write a simple payroll program that will display employee's information. Refer to the UML Class Diagram for the names of the variable and method. This should be the sequence of the program upon execution: a. Ask the user to input the name of the employee. а. b. Prompt the user to select between full time and part time by pressing either F (full time) or P (part time). c. If F is pressed, ask the user to type his monthly salary. Then, display his name and monthly salary. С. If P is pressed, ask the user to type his rate (pay) per…
