Study Notes
Procedure- Oriented Programming
- Focuses on a program's organization into functions or procedures.
- Each function carries out a specific task.
Console Programming
- Uses text-only interfaces within the Java programming method.
Swing Programming
- Enables developers to design graphical user interfaces.
Object-Oriented Programming (OOP)
- Utilizes objects as the core building blocks of software development.
- Objects represent entities with attributes (data) and behavior (methods).
Key Differences between OOP and Procedure-Oriented Programming
Organization
- Procedural: Data and functions are separate. Functions operate on global or passed data.
- OOP: Data (attributes) and functions (Methods) are encapsulated within objects.
Reusability
- Procedural: Functions can be reused, but managing related data requires manual effort.
- OOP: Objects are reusable and extensible, allowing creation of new classes based on existing ones (inheritance).
Maintainability
- Procedural: Managing and understanding the flow of data and functions can become complex as the program grows.
- OOP: Encapsulation and modularity improve maintainability by localizing changes to a class.
Key Concepts of OOP
- Encapsulation: Bundling attributes and methods within a single unit.
- Inheritance: A class inheriting properties and behaviors from another class.
- Polymorphism: Different objects responding to the same method call in unique ways.
- Abstraction: Hiding complex implementation details and showcasing only necessary features of an object.
- Modularity: Allows coding and understanding specific parts of a system without understanding the entire system.
- Reusability: Provides flexibility to use programs repeatedly.
Constructor
- A special method initializing object attributes upon object creation.
Classes
- Blueprints or templates for creating objects.
- Define the structure (attributes) and behavior (methods) of objects.
- Objects of the same class share the same structure and behavior.
Super Class vs. Sub Class
- Super Class: The base class, ancestor class, or parent class.
- Sub Class: The derived class, descendant class, or child class.
Non-Static Class vs. Static Class
- Non-Static Class: Requires instantiation.
- Static Class: Does not require instantiation.
Objects
- Instances of a class with attributes and behaviors.
- Can have unique values for their attributes, even if created from the same class.
Attributes
- Variables representing object state or characteristics within a class.
- Store data manipulable by methods.
State
- The current values of an object's attributes at a particular time.
- Can change as the object interacts with methods or other objects.
Methods
- Actions done by an object.
- Functions defined within a class specifying object behavior.
- Manipulate data within objects.
Abstract Method
- An empty method.
Interfaces
- Collections of methods indicating that a class has specific behavior beyond what it inherits from its superclasses.
- Define a common set of methods implementable by various classes according their needs.
Types of Methods
- Instance Method: Operates on an instance of the class (an object).
- Static Method: Belongs to the class, not any object instance. Doesn't modify object attributes and can be called on the class itself.
Packages
- Group related classes and interfaces in a structured manner.
- Enable groups of classes to be available only if needed.
- Eliminate potential conflicts among class names in different groups.
Notable Facts about Packages
- Java class libraries are contained in the package java.
- By default, Java classes only have access to classes within java.lang.
- To use classes from other packages, use an import statement.
