Thread: URGENT! Please help me. Thank You!

Okay, i got this coding from a friend. He is my old old old senior. Since i am really a total newbie in the course im taking at the moment, I asked him for a help. But he's not in the same college as i am anymore (he further his study away from our place) and he's been busy with his on project and group project, so he gave me this coding as a guide for my homework..because it is almost the same.

The things is I keep getting this on my command prompt(cmd),
"Note: Question5.java uses or overrides a deprecated API.
Note: Recompile with =Xlint:deprecation for details"

What is it actually? How can i fix it? Where to fix it? Please provide a step-by-step instruction for me for it is hard for me to understand this new subject

This are the codes..

I suggest that you avoid borrowing code, that instead you write it yourself. Sure it's fine to borrow ideas, but if you don't write it from the ground up, especially at this level, you'll never understand it and won't learn programming.

I'm not borrowing. He want me to use it as a guide. So i wanna see how this code of his work to get the idea. But when i try to run his code, i get that error instead. I didnt change anything, i just merely run it on cmd. That's it.

--- Update ---

And this is my actually works...which happen to have errors.

searchDrinks();
DrinksSystem.java:128: error: cannot find symbol
displayDrinks();
DrinksSystem.java:144: error: cannot find symbol
deleteDrinks();

symbol: method deleteDrinks()
4 errors

It's somewhat of an intelligence test -- to see if the original poster can follow simple orders.

So all in all, this is my codes. BUT, i get a LOT of errors instead...been doing this for 2 weeks (along with the other homework for Java Script in creating website which i already completed it) and i couldnt understand where or how this and that.

Yea, perhaps simple for some people but not me *sigh* This course is a whole different one. I mean i just get in a college and take this course just 2months ago, after completing my A Level, and im stuck with this kind of work which the lecturer expect us to understand it already without knowing there is a few of us like me who feel it so hard to understand.

I see two important issues:

1. Most importantly, you're ignoring your exceptions by having empty catch blocks. At least print the stack trace via e.printStackTrace(). Otherwise what you're doing is the programming equivalent of driving a car with blindfolds on.
2. Your code is all left justified. Certainly your instructor is asking you to submit formatted code so that he can be able to read it. Since you're asking us for free help, it's not too much for us to ask this of you as well.

Also, you'll want to leave all mention about "urgent" or "asap" out of your posts here since it isn't our urgency, and your question is no more important than any other question here.

I copy paste this directly from my notepad+. It isnt like that in my notepad+. I dont know why it became that when i posted up here.

--- Update ---

So, i try to post up again. I hope it looks the same as what i did in notepad+

hey, it worked! lol damn, im happy...pfftt

And just so you know, i havent done the Transaction Part. I wanted to do the simple one first (lecture said it simple not me), add delete search and display, which i get the errors. If this is okay, then i proceed to that Transaction Part.

And you're still ignoring your exceptions (and our advice that you not do this). I guess fixing this wasn't all that "urgent" after all.

Error.jpg

there, thats the error..sorry..having discussion with a partner as well..

Okay, tell me what exactly please. I mean, do i have to delete that throws exceptions or what? I dont understand thats why.

Please don't paste an image here. Instead paste the actual text held in the console. Since that's a Windows CMD console, simply right-click it, then click on Select All, and then press <enter>. Your text will have been copied to the clipboard. Then post the actual text here.

--- Update ---

Again, you should at least print out stacktraces:

try {
   // ... some code in here
} catch (SomeException e) {   // *** obviously you'll be catching a specific exception, not this
  e.printStackTrace();  //  ****** add this here ******
}

I did delete that as you said, it works. Well, at least form 15errors to 9errors..

Error2.jpg

Wow. I didnt know that. Thanks for the tip. And wait, i'll that coding first.

--- Update ---

Okay, i still have the same errors even after i add that one.

OK, can you repost your entire DrinksSystem class, but with well-formatted code? I think that the formatting will help us and you see just where the error may be. It looks like these methods are being placed where they don't belong.

When you said well-formatted code, is it like this?

Almost. Your indentations are still a bit wild and instead need to be uniform, so that our brains can understand better the levels of code blocks that the indentations signify. I suggest that you use 3 spaces per indentation, that you take extreme care to line them up correctly (or using an IDE have it format your code), because it will pay you back dividends, especially dealing with a large class like this. If you did your indentations correctly and neatly, you'd see in an instance that you're trying to declare a class before the code of another previous class has been fully closed. Line the code blocks up with good indentations and you'll see exactly what I mean. And then you'll be able to solve some of your errors (... you're missing a closing brace).

You would in fact see this:
