Abstract classes used when: Common abstract methods to be re-used for different clients. 'Extend' the class. Abstract classes do not have pre-defined methods, only abstract methods. T/F? False. Abstract class must have at least one abstract method, rest may be initiated pre-defined methods. Interfaces used when: All abstract methods and no pre-defined methods. 'Implement' the class. Local (method) variables must be defined but not initialized. T/F? False. Local vari...

or a method formal parameter p, which parameter mode guarantees that #p cannot appear n the ensures clause for the method's contract? a. clears b. replaces c. restores d. updates - ANSWER B. replaces You may reason about the behavior of Java code involving immutable types exactly as if they were primitive types because: a. "Immutable" and "primitive" are synonyms; there is no difference between them b. Computations involving immutable types are just as efficient as those involving ...
