Encapsulation: is like information Hiding.
Hiding the properites and behaviors of object and allowing outside access via public methods.
Example for Encapsulation:
============================
EmpDetails.java:
package com.oops;
public class EmpDetails {
private int empid;
private String empname;
public void setEmpid(int id){
empid=id;
}
public int getEmpid(){
return empid;
}
public void setEmpName(String name){
empname=name;
}
public String getEmpName(){
return empname;
}
}
EncapsulationExample.java
package com.oops;
public class EncapsulationExample {
/**
* @param args
*/
public static void main(String[] args) {
EmpDetails emp1=new EmpDetails();
emp1.setEmpid(1);
emp1.setEmpName("First");
System.out.println("Employee details id: "+emp1.getEmpid()+" and name:"+emp1.getEmpName());
}
}
Output
==========
Employee details id: 1 and name:First
