Let me teach you to read error messages.

The Exception will be in the format of:

1. some.package.name.SomeKindOfException: some.other.pack.SomeException
2. some.package.name.ClassName.methodName(Parameter);
3. at some.package.name.NameOfClass.method(FileName.java:100)
4. more lines similar to line 3

All you care about is line 1-3. The first line has the Exception that is thrown. The name of the exception is a good indicator. Like, NullPointerException is an exception that is thrown when you are accessing a pointer (or reference as Java uses) with a null value. The second line has the function or item that the Exception was thrown by. The third line shows exactly where in your code the error occurred. In my example, it would be in FileName.java at line 100.

If you don't know what the exception means, google the exception.

In your imitem class on line 124 inside of the registerItem function, there is a reference that you are trying to access that holds a null value.

And because the JRE is amazing, for most errors you can tell a programmer what is wrong just by looking at the error for most beginner mistakes. That being said, we cannot tell you how to FIX it without your source code; please provide the source code of your imitem class.
