In Java, encapsulation is the process of binds together the data and methods in a single unit. It's safe from outside interference and misuse.
Example: Capsule, it is wrapped with different medicines.
Data encapsulation is the process of binding the data, and the methods that use them and data abstraction is the process of showing only the interfaces and hiding the implementation details from the user.
The primary goal of encapsulation is the insulation of a particular object class internal detail and show the interfaces.
If the data member is declared Private then it accesses within that package or class only.
Example:
class Book{
private String Bookname;
//getter method for name
public String getName()
{
return Bookname;
}
//setter method for name
public void setName(String Bookname)
{
this.Bookname=Bookname;
}
}
public class Encapsulation{
public static void main(String[] args){
Book b=new Book();
//setting the value for name field
b.setName("Programtpoint");
//getting value for name field
System.out.println(b.getName());
}
}
