A method defined in a class can access the class’ instance data without needing to pass them as parameters or declare them as local variables.
Answer: True. Explanation: The instance data are globally available to all of the class’ methods and therefore the methods do not need to receive them as parameters or declare them locally. If variables of the same name as instance data were declared locally inside a method then the instance data would be “hidden” in that method because the references would be to the local variables.

- 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.
