Java Beans in Java

Hi Vipendra,


Java bean: It is a development component for performing a task in an application. Any ordinary java class with a set of variables and methods can be called as javabean. The methods present in a java bean must follow a naming convention. A java bean can be used in a web application to store the state of the users.

Creation process of a java bean:

   1. Create a class in a package as the bean class.
   2. Provide the required variables as the properties.
   3. Provide setter and getter methods for each of the variables.
   4. Store the package folder inside a classes folder.
   5. Compile the file as ordinary java file.


Store the following bean file in (E:\Servlet\WEB-INF\classes\pack1)

Example:

package pack1;
public class mybean
{
  private String name,pass;
  public void setName(String n)
   {
      name=n;
    }
     public void setPass(String p)
   {
      pass=p;
    }
  public String getName()
    {
     return name;
      }
    public String getPass()
    {
     return pass;
      }
  }

Compile of bean:- javac mybean.java
