explain it to me

I have no idea what you mean by "hardcode" in this context.

actually,i didnt know too,what the meaning of hardcode,but i got an assignment,and this assignment give me a task to:

"Make a program with JSP using servlet just for login from index.jsp"!!

and in this question,i must answer it,or maybe using servlet just for login itself,we can name it hardcode,so it have another name.

correct me if i am wrong,thanks.

or maybe you can help me with that question,to help me "Make a program with JSP using servlet just for login from index.jsp"??

What have you done so far? Show your work.

It is so clear from your question that you have to make one jsp page named index.jsp and put form into it.
Put textboxes and buttons you need on login page and insert the path of servlet onto the action attribute of form tag.
When you click on submit button in form tag then it will go to servlet and do your coding there by making connection with database.

Please post your jsp and servlet code.

i don't know what you mean by hardcoded.
but in our college(when i got assignments) we generally refer hardcoded mean, everything should be coded by me, no api's, no plugins should be used.

Well that should be named "Handcoded".

yes it should be..
but we called hardcoded, perhaps because everything is coded manually so it becomes hard to do, as compared to do by using api's and plugins.
but i m not sure why it's called hardcoded.

That is hilarious.

i also think so...

the hardcoded is probably asking you to put your password in the verification code. meaning you can only change the password inside your code. you don't have to save the password on a database or any other medium.

This thread is insane, but I think I know what the OP means:

for a mock login screen, I have "hardcoded" the users password. That is, in the servlet, just say

and then compare what the user has entered to this hardcoded string.

The opposite is that the password, or hopefully the hash of the password is pulled out of a database somewhere and compared to the string the user has entered.

hardcode means, the username and password will be coded in controller itself. While executing the program , when user enters username and password then verification will not be done by retriving the values from database . Instead the checking/matching will be done with hardcode values.

hardcode means you have to take username and password in your code not from database
