HI,

1.It helps to assign the serializable data to the tagged classes.

2.Java servelets runs inside the web server.

IN CGI,the process is external to the web server

Hi

i think

2)CGI, which was a process based, that is for every request made by client,even for the duplicate request an extra process is created.

Servlet Technology is very much efficient, Servlets provide a component-based, platform-independent method for building Web-based applications, without the performance limitations of CGI programs.

regards

1. What is serializable Interface ?
serializable interface is used to automatically write to a stream.

to save the properties in case of java beans

2. What is the difference between CGI and Servlet ?
CGI is used to provide graphical interface.servlets run on the backside of CGI

3. What is the use of Interface ?
to provide multiple inheritance

hi,

3) java is not 100% an OOP Language because it doest not support multiple Inheritance which is a property of OOP but we can get the facility of multiple inheritance my extending a class and implementing few interfaces...

1.Serializable:

Thewriting the object in to streams of byte.This is can be used in RMI(Remote Method Innvocation).

It is an marker interface where this can be used in transferring one object to other over the network.

Hi freinds
java doesnt support multiple inheritance because i like to say a small example

Think tat there is an interface A with a method "sample()" and there are two subclasses B,C implementing that interface and providing different implementations for tat "sample()" in there own classes and suppose let us assume for a while tat if java supports multiple inheritance ,nou the picture comes into reality assume there is a class D which extends both B & C nou if we want to inherit the "Sample()" we cannot decide that which class's sample() will execute so to avoid this messy javasoft deleted the concept of multiple inheritance .i think im clear if there are any more doubts pls mailme to mrgharikrishna@gmail.com
