For example, when using a cell phone, you can figure out how to answer incoming calls and respond to text messages. Thanks to data abstraction, you can't tell how the phone itself transmits signals. The purpose of data abstraction is to expose only the essential elements of a device.
What is abstract method in Java with example?
Abstract methods are those types of methods that don't require implementation for its declaration. These methods don't have a body which means no implementation. A few properties of an abstract method are: An abstract method in Java is declared through the keyword “abstract”.
What is an example of an abstraction in it?
Examples of abstraction in computer science include high-level programming languages like C++ and Java for data abstraction, and software applications or functions/methods in programming languages for procedural abstraction.
Abstraction in Java
Abstraction is a process of hiding the implementation details and showing only functionality to the user. Another way, it shows only essential things to the user and hides the internal details, for example, sending SMS where you type the text and send the message.
