Could you pls tell me what is the need for getter and setter methods?

Do these methods only used in beans and EJB?

Can I use retriveName() instead of getName() ?

Do these method are mandatory

Thanks

They are not necessary unless you are working within some type of framework that expects them (yes, this includes JavaBeans, EJB, Struts, and others...).

However, I think most people would agree it is a very good idea to follow these conventions. Some of the smarter IDE's will automatically generate get/set methods for you, and recognize that get/set methods are related. Furthermore, if at some point you find yourself introspecting (say, for logging or debug purposes) you'll be able to leverage tools like Jakarta's BeanUtil.

I think getX method or setX method is standard in Java, though there seem to be some debates. In the class java.util.Calendar, for example, those methods have vital positions.
