To achieve abstraction in JAVA we set data fields as private which means now no outside class can access it. However to allow outside class to read and write the data on those data fields we create public getter and setter methods. Encapsulation means hiding the internal details of an objec...
Example 1:Lets now understand abstraction concept using real life examples of different sounds created by animals. For example Cat does Meow and Lion Does Roar. We will display different sounds using Abstraction in JAVA. Step 1:First create a new project in Eclipse and create a abstract class ...
Since abstract class allows concrete methods as well, it does not provide 100% abstraction. You can say that it provides partial abstraction. Abstraction is a process where you show only “relevant” data and “hide” unnecessary details of an object from the user. Interfaceson the other hand ...
a method that adds two integers. The internal processing of the method is hidden from the outer world. There are many ways to achieve abstraction in object-oriented programmings, such as encapsulation and inheritance. A Java program is also a great example of abstraction....

An abstraction. This abstract model gives programs the powerful capability of generalization. Any instance, now, may be treated an object. Usually, we access methods defined directly on a class. But methods from the Object class are universal, and help in many program parts. Method Helpers. Wit...
SLF4J API serves as a simple abstraction for various logging frameworks. Logging codes written with SLF4J in the embedded components and libraries are compatible with the preferred logging framework. At runtime, SLF4J codes are bound to the logging framework in the classpath. Logback-classic modul...
