Expert Solution & Answer
Chapter 1, Problem 5E
Explanation of Solution
Object
- Depending on whether it is
mechanical or electronic watch, there will be different design for power source location, watch casing, hands and watch protection. - The user check out from watch is position of its hands to read time.
- The rest of watch’s functioning is encapsulated within the casing.
- Before time of a watch is read, it must have been constructed from its engineer’s drawings or design plans.
Attributes
- Apart from the ability to read time, it has attributes such as color, constituent material, power source and extra properties such as water resistant, size, its ability to keep track of date and month.
- The watch’s attributes are representing part of its design in its engineering diagrams.
- Every watch will maintain its own attributes.
Behavior
- For a mechanical watch, the behavior or method hides the hand and wheel movement mechanism from the watch.
- Behavior and method are similar terms.
- Behavior house the same way as watch perform its tasks.
Class
- A class is used to embody a set of methods that aid in performing class’s tasks.
- A class can be seen as blueprints and in the case of watch, the engineering drawings or design plan from which watch class is created.
- It will hence contain methods for reading, changing time and so on.
Inheritance
- With inheritance, a new class can be created from the existing class.
- The new class absorbs the characteristics of the existing class.
- Alarm clock may contain general watch characteristics such as hands and timing parameters but at the same time it may have an extra customized alarm device...
