Java Program for Encapsulation

Encapsulation in Java with Example – Encapsulation in Java is a mechanism of wrapping the data (variables) and codeacting on the data (methods) together as a single unit. In encapsulation, the variables of a class will be hidden from other classes, and can be accessed only through the methods of their current class.

public class EncapTest{

   private String name;
   private String idNum;
   private int age;

   public int getAge(){
      return age;

   public String getName(){
      return name;

   public String getIdNum(){
      return idNum;

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

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

   public void setIdNum( String newId){
      idNum = newId;
