Tutorial: Java General Java Encapsulation Tutorial

Encapsulation is the concept of hiding the implementation details of a class and allowing access to the class through a public interface.

Tutorial Details:

Java Encapsulation

Encapsulation is the concept of hiding the implementation details of a class and allowing access to the class through a public interface. For this, we need to declare the instance variables of the class as private or protected.

The client code should access only the public methods rather than accessing the data directly. Also, the methods should follow the Java Bean's naming convention of set and get.

Encapsulation makes it easy to maintain and modify code. The client code is not affected when the internal implementation of the code changes as long as the public method signatures are unchanged. For instance:

public class Employee
{
private float salary;
public float getSalary()
{
return salary;
}
public void setSalary(float salary)
{
this.salary = salary;
}
