question: public static boolean isCompatible ( Class expect , Class type ) { if ( expect . isArray ( ) ) { expect = expect . getComponentType ( ) ; } return expect . isAssignableFrom ( type ) ; }
target:  This is used to determine whether the provided base class can be assigned from the issued type. For an override to be compatible with the field type an instance of the override type must be  assignable to the field value.
