What is encapsulation?

Encapsulation :  It is a process by which wrapping code and data into a single unit.

Example : A java bean is a best example of heighly encapsulated class where any instance variable declared as private and these private variable can access through public method.

package com.pky.com;  
public class Employee{  
private String name;  
   
public String getName(){  
return name;  
}  
public void setName(String name){  
this.name=name  
}  
}  


//save as EmpTest.java  
package com.pky.com;  
class EmpTest{  
public static void main(String[] args){  
Employee e=new Employee();  
e.setName("Pradeep Yadav");  
System.out.println(s.getName());  
}  
}

Output :
Pradeep Yadav

Advantage of Encapsulation :

* you can make the class read-only or write-only.

*  you can control over the data
