Homework Help for Java

[DonE]

Help me please. I am having problems with my homework assignment. We are to create a product class that hold the item number, the name of the product, the number of units in stock, and the price of each unit. Here is my problem. I have written the program ( I use netbean) and I have encountered plenty of errors. The error messages that I get are as follows:

1. illegal start type
2. cannot find symbol
3. operator cannot be applied
4. assignment to itself

Here is what I have done so far. It would be great if there would be someone that would be able to help me throughout the next few weeks of assignments. Thanks

1. illegal start type
2. cannot find symbol
3. operator cannot be applied
4. assignment to itself

The compiler tells you a lot more than just that, e.g. it shows the line number
where the compilation error was noticed, it displays the offending symbol(s)
and more when it can. Please don't let us guess about that information.

kind regards,

Jos

Just a reminder that next time, use code tags when you are to post java codes... ;-)
