E:\IT 215 Java Programming\public class Inventory.java:39: class, interface, or enum

[tlouvierre]

Hello How's it going over there? Everything here is fine. The weather is a little under the weather but other then that it ok. I have tried this one with you before and I forget the out come but it must not have worked because here I am again. Sorry for the inconvience but like everyone else I am pressed for time but I do have a little time to spare. So Great. Now I have this program and it states E:\IT 215 Java Programming\public class Inventory.java:39: class, interface, or enum expected
import java.util.Locale;
^
E:\IT 215 Java Programming\public class Inventory.java:40: class, interface, or enum expected
import java.text.NumberFormat;
^
2 errors
And I am not real sure as to why. Well here is the code. I hope you find something.

I would really much appreciate it if you could find the errors and tell me why I am getting them.. I need this program to work.

[emceenugget]

is your file actually named "public class Inventory.java"? your file name should be the same as your class name...

[tlouvierre]

is your file actually named "public class Inventory.java"? your file name should be the same as your class name...

Yes. The file is correct. What does that have to do with anything other then the class name that is not where I am getting the error. I get the error at Import.util.Locale and etc. I do not understand. This is due tommorrow.

[tlouvierre]

I tried what you are thinking before and rearranged the public class but noting happened I still got the locale errors.

[Singing Boyo]

If you could indicate the exact line in your code where the error occurs (just add something like //<<<<ERROR HERE>>>>) it would be much easier to help you...

[OrangeDog]

File name should be just "Inventory.java"

ok... are the classes in two separate files? If not, try doing that, may work then. If for any reason they need to be in the same file, the DVD class goes inside the Inventory class, and the imports causing the error go at the beginning of the file.

Hi You gave me a great Idea and I removed the Import.util.Locale from position line 39 and the other line I can't remember and put it in the front of the program. Removed completely from lines 39 and forty and re ran it and this is what i got. E:\IT 215 Java Programming\public class Inventory.java:25: not a statement
for ( int number=0; counter; prodArray.list, counter++ )

[Singing Boyo]

for ( int number=0; counter; prodArray.list, counter++ )

this is incorrect. counter; is not a statement. it should be something like

for (int number=0; number<countUpTo;  number++)

See The Java Tutorials: The for Statement for more information on for loops and how they work

[tlouvierre]

Ok will try.

I did what you suggested and I get back these 3 errors.

[Singing Boyo]

for ( int number=0; counter; prodArraylist; counter ++)

Still wrong... please read the tutorial from my last post. It will give you far more information than I can. One thing I will tell you is that if you do not have exactly 2 semicolons (';') within your brackets it will not work.

EDIT: "One thing I will tell you is that if you do not have exactly 2 semicolons (';') within your brackets it will not work."

This is not necessarily true (as the tutorial will tell you) If you use a colon (":") to iterate through an array, it would work as well...

Good try but these are the errors that I am getting with your suggestion. It is late so I will turn in but try again in the morning with the tutorial. Thank you for your time.

[Singing Boyo]

Well... I will just point out that countUpTo was not declared (it was pseudocode... the number you want to count up to with the for loop) and neither was counter (judging by the error messages.
