Encapsulation in Java

[Raveendran Hs]

What is the best way define a Encapsulation in java.
Can you please give the good example for this

[Pramod P Deore]

In Encapsulation we making the fields in a class private and providing access to the fields via public methods.

public class EmpTest{

   private String name;
   private String id;
   private int age;

   public int getAge(){
      return age;
   }

   public String getName(){
      return name;
   }

   public String getIdNum(){
      return id;
   }

   public void setAge( int newAge){
      age = newAge;
   }

   public void setName(String newName){
      name = newName;
   }

   public void setIdNum( String newId){
      id = newId;
   }
}

In this code you can not access variables name , id age from outside the class directly . To access them you have to go through getter and setter methods. And here if you want then you can add some logic which will protect your variables.
