I need a tutor in order to pass my class in Java Programming!

Question

I'm having a lot of trouble keeping up in my online course. Because there is no class room, I find it difficult to ask questions. The time lap between question and answer makes it extra difficult to concentrate and stay focused on the problem. I would really like someone to be my tutor. Corresponde via email so that I can get help quicker and stay on track.
I'm suppose to write an array in order to keep inventory. I have no idea where to even start. Here is the assignment, if you can help me and point me in the right direction, or show an example of codes I can use, it would be greatly appreciated.
1) Create a product class that holds the item number, the name of the product, the number of unites in stock, and the price of each unit.
Item # 1, Red Hanging Candle Holder, 24, $12.00
Item # 2, Blue Hanging Candle Holder, 24, $12.00
Item # 3, Green Hanging Candle Holder, 24, $12.00
Item # 4, Yellow Hanging Candle Holder, 24, $12.00
2) Create a Java application that displays the product number, the name of the product, the number of units in stock, the price of each unit, and the value of the inventory (the number of units in stock multiplied by the price of each unit).

Answer 1

God bless, Darryl. My time is more valuable to me.
Maybe this arrangement works because you need the
instruction as much as the OP does. The only
question is: who will provide it? If neither person
knows more than a month's worth of Java, how is new
information brought in?
Thanks duffymo for your blessing. As programming is just a hobby for me -- since 1983 -- I agree that my time is (much much) less valuable than yours. And yes, I expect the learning process to be mutually beneficial. And while I don't plan to make my living off java, I believe in doing things correctly or not at all. My one month experience in Java is backed up by programming in more languages than most professionals use in a lifetime, on platforms starting from pre-DOS systems with CTDs and a single-line display through DOS, xenix, PDP-11, MicroVAX and every version of Windows from 95 onwards.
In any case, don't you think it would help if the simplest of questions were kept off these forums and solved in mutual self-help groups? some of whose members had nore time than others to spend on Googling and searching the forums? The first benefit would be to those who have progressed beyond the obvious, as you seniors would have more time to answer their pleas for help instead of getting bogged down in badly or unformatted code with all the trappings of cut-n-paste, meaningless comments that seem to be intended more for the teachers than the learners -- I could go on and on.
I apologise for what I'm about to do; I do really agree with the general feeling on the forums that OPs benefit much more from being guided towards their goal than from being spoonfed a code that works. But I would really appreciate your critique of this code, which is my first console application. It took about half an hour, including Googling. I am aware that there are absolutely no comments, and the output columns don't line up, due to my as yet inadequate knowledge of output formatting. Anything else you can point out would help me in my learning process.
Thanks for your time, Darryl

}The forum software seems to have reduced my indentation by 1 space in many lines, they line up correctly in Notepad.
