In computer science and object-oriented programming (OOP), encapsulation refers to the practice of bundling data and methods operating on that data into a single unit called a class. This mechanism restricts direct access to certain components while exposing controlled interfaces for interaction. By ...

Part of the book series: Undergraduate Texts in Computer Science ((UTCS)) 509 Accesses Abstract An important key to software productivity is software reuse. With respect to data structures, an important key to software reuse is the encapsulation of classes of data structures in ways that encour...
Data Encapsulation, also known as data hiding, has been recognised as an important concept in the construction of maintainable programs [5]. It is a concept that should form part of a modern programming course. Such a course ought to provide practical experience of encapsulating data. ...
Encapsulationtakes information from a higher layer and adds a header to it, treating the higher layer information as data. It is often said, “One layer's header is another layer's data.” [3] For example, as the data moves down the stack in the TCP/IP model, Application Layer data ...

Explanation: In Java programming language, the encapsulation is a mechanism of wrapping the data (variables) and code acting on the data (methods) together as a single unit. It is a object-oriented programming concept. Comments and Discussions!
MyClass.java:5: error: name has private access in Person System.out.println(myObj.name); ^ 2 errors Instead, we use thegetName()andsetName()methods to access and update the variable: Example publicclassMain{publicstaticvoidmain(String[]args){PersonmyObj=newPerson();myObj.setName("John"...
