> A java.lang.NoSuchFieldError is typically thrown when you remove a field but do not recompile the client code that calls the field. However, the message does not indicate in which class the field was not found. 
> 
> Additionally, java.lang.NoSuchFieldError is thrown if the field is still present but the types are incompatible. For example, if a field is first defined as int, and later changed to long without recompiling the client. The error text has been expanded to include the class name and field type. Verified with tier 1-4 tests.
> 
> Old output:
> `Exception in thread "main" java.lang.NoSuchFieldError: x
>         at NoSuchFieldMain.main(NoSuchFieldMain.java:3)`
> Example output:
> `Exception in thread "main" java.lang.NoSuchFieldError: Class Other does not have field 'int x'
>         at NoSuchFieldMain.main(NoSuchFieldMain.java:3)`
