It seems there's an error in the syntax of the java command that you are trying to use to run your program. Exactly what are you typing?

[Daminic24]

This is what im doing:

Separate arrays to store individual details of each item
searching method 
useful comments, good indentation, good use of variable names


Display a menu of options (as below) to allow a user to manipulate three arrays which together represent prizes in a programming competition, until quit is selected.
o   Enter  details of a prize ( user is requested to enter the details of a prize from the keyboard)
o   Print the details stored for all prizes 
o   Search for a prize with a particular value OR by description
o   Quit
Three arrays to represent details relating to prizes. 
   Declaration and initialisation of variables.
   Separate arrays to store individual details of each prize.  A  prize requires storage of :
•   A description 
•   colour
•   value of prize 
   A menu of options dependent on an integer variable
The facility to display how many prize details are stored in the arrays.
The facility to request and accept input of a prize,  and store in the next empty array elements.
A facility to print the details of all prizes stored in the arrays.
A search method to allow searching for a prize (with a particular value OR by description).

Very interesting, but irrelevant to my question.
You are getting the java command wrong. What exactly did you type?

[Daminic24]

can you give me example of what you mean? ive only been doing java for a year so not 100% sure.

[JamesCherrill]

What exactly did you type at the command prompt when you were trying to run your java program? I don't know how to make that question any simpler.

[Hiroshe]

What action did you perform to try to run the program?

You have code. You an error. How did you run the code to get to the error?

Be specific.

[Daminic24]

Im using jcreator i built the file then i ran it, i tried the same thing on eclipse and it worked fine?

[JamesCherrill]

Looks like something wrong with jcreator setup? The code isn't the problem.
