Java Bean

What is Java Bean?

Java bean is a simple java class with instance variables (all private) and each instance variable having getter and setter methods (public) for them.

Example :

 class Person {  
 private int id;  
 private String name;  
 private String address;  
 public int getId () { return id; }  
 public String getName () { return name; }  
 public String getAddress () { return address; }  
 public void setId (int id) { this.id = id; }  
 public void setName (String name) { this.name = name; }  
 public void setAddress (String address) { this.address = address; }  
 }
