Exercises

1. Create new classes for each real-world object that you observed at the beginning of this trail. Refer to the Bicycle class if you forget the required syntax.

2. For each new class that you've created above, create an interface that defines its behavior, then require your class to implement it. Omit one or two methods and try compiling. What does the error look like?

3.whats meaning Object Oriented Modeling.What are difference Object oriented modeling and object oriented programming?

please explain this exercises for our knowledge.

Objects

Objects are the building blocks of an object oriented program .A program that uses object oriented is basically a collection of objects.Objects are the basic runtime entities in an object oriented system

The super class

The super class,or parent class contains all the attributes and behaviors that are common to classes that inherit from it
eg:
In the case of the Mammals class,all mammals have similar attributes.such as eye color and hair colors,as well as behaviors such as gone rate internal heat and grow hair.so it is not necessary to duplicate then down the inheritance free for each type of mammal

RUP & Software Development

How do we use RUP to develop industry based software applications?

Thinking about the “Faculty of Applied Sciences”.

Activity

1. Try to identify different objects in this faculty. Clearly describe the states and behaviors of each object.

2. Can you group them in to classes according to the common states and behaviors?

3. Try to identify the Inheritance of above mentioned classes and try to show the inheritance relationship?

4. Try to identify polymorphic behavior of defined inheritance relationship in the previous step?

Observation

As you do, you'll notice that real-world objects vary in complexity; your desktop lamp may have only two possible states (on and off) and two possible behaviors (turn on, turn off), but your desktop radio might have additional states (on, off, current volume, current station) and behavior (turn on, turn off, increase volume, decrease volume, seek, scan, and tune). You may also notice that some objects, in turn, will also contain other objects. These real-world observations all translate into the world of object-oriented programming.
