Example of JavaBeans

Before going to write a JavaBean, here are some basic rules. A JavaBean should be public, should has no argument default constructor and should implement serializable interface. Keep these basic rules in mind before writing a JavaBean.

public class StudentsBean implements java.io.Serializable {

   private String firstName = null;

   private String lastName = null;

   private int age = 0;

   public StudentsBean() {

   }

   public String getFirstName(){

      return firstName;

   }

   public String getLastName(){

      return lastName;

   }

   public int getAge(){

      return age;

   }

   public void setFirstName(String fn){

      firstName = fn;

   }

   public void setLastName(String ln){

      lastName = ln;

   }

   public void setAge(int a){

      age = a;

   }

}
