Study Notes
Understanding Objects
- An object can be anything in the real world or an imaginary concept.
- In programming, objects are abstractions used to model real-life entities.
Models and Instances
- A Model represents a broader idea or concept that can be illustrated.
- A Set of Entities can be represented by a model, with each specific example considered an instance.
- Examples include:
- Animal Model: Includes instances like eagle, whale, and deer.
- Monster Model: Includes instances like centaur, dragon, and werewolf.
- Appliance Model: Includes instances like stove, refrigerator, and washing machine.
Object-Oriented Programming
- Java is a leading object-oriented programming language, emphasizing the use of objects.
- Focuses on defining and using models and instances to facilitate programming tasks.
Defining Object Model
- Object modeling involves two primary components: Attributes (State) and Behavior.
Attributes (State)
- Describes the current characteristics of an object, with the understanding that these attributes can change over time.
- Examples of attributes for a Light Bulb:
- Is powered: Indicates the bulb's on/off status.
- Color: The color emitted by the bulb.
- Watts: The power required to operate the bulb.
- Examples of attributes for a Bank Account:
- Account number: Unique identifier for the account owner.
- Balance: The total amount of money in the account.
Behavior
- Refers to the actions an object can perform, which can alter its state or provide information about it.
- Examples of behaviors for a Light Bulb:
- Turn on: Activates the light bulb.
- Turn off: Powers down the light bulb.
- Flip switch: Toggles the power state of the bulb.
- Check status: Reports the current power status.
- Check color: Reveals the color of the bulb.
- Check watts: Indicates the power needed by the bulb.
- Examples of behaviors for a Bank Account:
- Deposit: Adds more money to the account.
- Withdraw: Removes money from the account.
- Inquire balance: Checks the remaining balance in the account.
Object Characteristics
- Objects are anthropomorphic, capable of performing specific tasks but cannot act independently; they require commands from other objects.
- Effective communication between objects is essential for program functionality, especially in languages like Java.
- Objects serve as abstractions, functioning like a black box where specific details are concealed while general information is available.
- This abstraction reduces complexity in programming by allowing the definition of object features separately.
