Don't feel alone.  This entire forum is dedicated to people like you learning and struggling with Java.  You should try googling first, but many times that is not enough.

If you're interested in really getting the most out of this forum, look through the wiki about how to ask questions.

I'm the outlier here.  For getting input from the keyboard, the only function I use from Scanner is nextLine().  This is for two reason.  One, I want to be able to detect when the user only presses <Enter>.  I use this behavior to enter default values.

    What is the meaning of the Universe? (default = 42):

The other is that if you use nextInt() or any of the other nextXxx() functions you can run into this problem:

    What is your age? 6e

Here the user has slipped and accidentally typed 6e instead of 64.  I don't want the program to accept 6 and leave e in the buffer.  I want the program to ask for the age again.

Campbell and I do agree on one thing: you really need to write a utility class to wrap Scanner (or maybe BufferedInput?).  Add prompting and validation and you have a handy class.  I call mine Inputer and it's freely available on my GitHub repo.

I'm going to assume that your question is, How do I retrieve an enum values from a String value?  If that is correct, then try this:

This is still not helpful, I'm afraid.

* Code doesn't compile
* Code not formatted correctly
* Many unnecessary lines of code
* Not clear what the code's intent is.

I took the String that you created and modified it back to an SQL statement (below).  I may be wrong, but I think you go off the rails at the AND that I marked with a comment.  It seems that it could be controlled by the second WHERE clause, but the parentheses do not match.

Does there need to be a main() method in this class?

Thanks for the clarification.  Off-by-one errors are hard.

Harry and I have been communicating via PMs and I encouraged him to post here.  I believe he's asking it if there other ways -- especially notifications -- that a user can be alerted when someone posts on a thread that the user is following.

Harry, the answer is that currently email is the only option, but someone might be willing to make this modification in the future.

Here are some comments on your code not related to the subject of the thread:

* The Java convention is to start a variable with a lowercase letter.
* final int Limit = Integer.parseInt("1000"); can be simplified to final int Limit = 1000;
* If you follow the convention, this code
would be written
* It's a good idea to get out of the habit of posting all your code in the main() method.  A standard template for this would look like this:

It could be a dead end -- in the sense that there's no through traffic.  Or it could just be a private road.  The sign is ambiguous.
