A class design requires that a particular member variable must be accessible by any subclasses of this class, but otherwise not by classes which are not members of the same package. What should be done to achieve this?
A. The variable should be marked public.
B. The variable should be marked private.
C. The variable should be marked protected.
D. The variable should have no special access modifier.
E. The variable should be marked private and an accessor method provided.
The correct answer is C
Explanation: See the section on the protected modifier.

- Method decomposition is the process of creating overloaded versions of a method that do the same thing, but operate on different data types.
- The println method on System.out is overloaded.
- A method defined without a return statement will cause a compile error.
- If a method takes a double as a parameter, you could pass it an int as the actual parameter.
- The different versions of an overloaded method are differentiated by their signatures.
- The number and types of the actual parameters must match the number and types of the formal parameters.
- The return statement must be followed a single variable that contains the value to be returned.
