Let’s see one moreexample of abstraction in Java using interfaces. In this example, I am creating various reports which can be run on demand at any time during the application’s lifetime. As a consumer of the report, a class needs not to know the internals of the report’s run(), ...
Difference between Abstract Class and Interface in java Method overloading in java Method overriding in java Encapsulation in java with example Polymorphism in java with example Inheritance in Java Can we override static method in java Dynamic method dispatch in java Can we overload main method in...
The best explanation of Abstraction is using the common example of sending SMS. When a user send SMS, he simply enter the address, type message in the text box and send it. He doesn’t know what is happening behind the scene when this message is getting send to the other user. So her...
Example of Encapsulation in Java classPerson{privateString name;privateintage;// Getter method for namepublicStringgetName(){returnname;}// Setter method for namepublicvoidsetName(String name){this.name=name;}// Getter method for agepublicintgetAge(){returnage;}// Setter method for age with ...
Giving an example for abstraction: Consider that you are switching on the fan. In abstraction, all you want is that whenever you switch it on, the fan should rotate. You are not concern how does the fan rotate, how much electricity does it consume, how does the capacitor in fan consumes...
Let's convert the Animal class we used in the Polymorphism chapter to an abstract class:Remember from the Inheritance chapter that we use the extends keyword to inherit from a class.ExampleGet your own Java Server // Abstract class abstract class Animal { // Abstract method (does not have ...
To work with such abstract actors, we only need to know about the public APIs that we will use. We need not to care about how they perform their work. For example, in the previous example ofReportWriter, we have defined thewriteReport()method that clients must use to generate the report...
In simple terms, abstraction “displays” only the relevant attributes of objects and “hides” the unnecessary details. For example, when we are driving a car,
with slight or no amendment. Therefore, it works as your Master Data. A real-world example of Encapsulation: Let’s take an example of mobile devices to clarify the Abstraction vs Encapsulation in Java. Using smartphones, you can perform tasks like capturing photos, recording audio/video, ...
5. Abstraction in Java Abstraction in Java is implemented throughinterfacesandabstract classes. They are used to create a base implementation or contract for the actual implementation classes.Car.java: Base interface or abstract class package com.journaldev.oops.abstraction; ...
