True False - Answers True Variables and constants are ____ within, or local to, only the method in which they are declared. in scope out of bounds out of scope limited - Answers in scope When a data item is known to all of a program's modules, it is a ____data item. scope defined local global - Answers global Programmers use the term ____ to describe any extra time and resources required by an operation. black box overhead overload cohesion - Answers overhead Using implementation hiding means that the ____ is the only part of a method with which the method's client interacts. argument list interface to the method parameter list internal detail - Answers interface to the method ____ refers to how the internal statements of a method serve to accomplish the method's purpose. Coupling Cohesion Bonding Binding - Answers Cohesion ____ is a measure of the strength of the connection between two program methods. Coupling Cohesion Bonding Binding - Answers Coupling ____ occurs when methods excessively depend on each other and makes programs more prone to errors. Late coupling Loose coupling Tight coupling Weak coupling - Answers Tight coupling ____ occurs when methods do not depend on others. Tight coupling Loose coupling Data coupling Abstract coupling - Answers Loose coupling Programmers refer to hidden implementation details as existing in a(n) ____________________. black-box white-box clear-box empty-box - Answers black-box Which of the following is considered by the text to be the most important consideration when designing a class?
