Object-Oriented Design

Flashcards summarizing key vocabulary and concepts from Chapter 7 on Object-Oriented Design.

Object-Oriented Design

A programming paradigm based on the concept of 'objects' that can contain data, in the form of fields, and code, in the form of procedures.

Software Development Activities

The four basic activities involved in creating software: establishing requirements, creating design, implementing code, and testing the implementation.

Static Modifier

A keyword used to declare a class member as belonging to the class itself rather than to instances of the class.

Interfaces

A contract that defines a set of methods that a class must implement.

Enumerated Type

A special data type that enables a variable to be a set of predefined constants.

Method Overloading

The ability to create multiple methods with the same name but different parameters.

GUI Design

The process of designing the user interface of a software application.

Mouse Events

Events related to mouse actions such as clicks, presses, and movements.

Class Relationships

The various ways classes can relate to each other, including dependency, aggregation, and inheritance.

Dependency

A type of relationship where one class relies on another, typically through its methods.

Aggregation

A has-a relationship where one class is composed of one or more objects of another class.

Inheritance

A relationship in which one class derives from another, inheriting its fields and methods.

Method Design

The process of defining how a method will function, including its signature and functionality.

Low-Level Design

Detailed planning of each method within a program.

Debugging

The process of identifying and fixing errors in a program.

Testing

The process of evaluating a program to ensure it performs as intended.

Parameters

Values passed to methods that influence their operation.

Exceptions

Unexpected events that disrupt the normal flow of a program.

Static Variables

Class variables that are shared among all instances of a class.

Static Methods

Methods that belong to the class rather than any specific instance.

This Reference

A reference within a class that refers to the current object instance.

Abstract Method

A method declared without an implementation, meant to be defined in derived classes.

Default Method

Methods in interfaces that have an implementation and allow backward compatibility.

HashCode

A method that returns an integer representation of an object, primarily for use in hash tables.

Equals Method

A method used to determine if two objects are logically equivalent.

Constructor

A special method used to initialize new objects.

Instance Variables

Data fields that store the state of an object.

Visibility Modifiers

Keywords used to control access to class members (public, private, protected).

Parameter Passing

The way arguments are passed to methods (by value in Java).

Complex Number

A number that has both a real part and an imaginary part.

Iterator Interface

An interface that provides methods for iterating over collections.

Iterable Interface

An interface that defines a collection that can return an iterator.

Underlying Data Structure

The internal data organization that supports the operations of a data type.

Slogan Class Example

Demonstration of the use of static methods and variables in tracking object creation.

User Interface Goals

Objectives to make software user-friendly and efficient.

Keyboard Events

Events generated by user keyboard interactions.

Event Handling

The mechanism that enables a program to respond to events like user actions.

Instance Creation

The process of creating an object from a class.

Syntax Errors

Mistakes in the code that violate the language rules.

Runtime Errors

Errors that occur during program execution, leading to abnormal termination.

Semantic Errors

Logical errors that cause the program to behave unexpectedly.

Method Signature

The method name along with its parameter types.

Polymorphism

The ability of different classes to be treated as instances of the same class through a common interface.

Method Documentation

Descriptive comments explaining method functionality.

Java Collections Framework

A unified architecture for representing and manipulating collections.

Resource Management

The practice of efficiently managing an application's resources, such as memory and file handles.

User-Centered Design

An approach to design focusing on the needs and wants of the user.

Method Decomposition

Breaking down a large method into smaller, more manageable sub-methods.

Loops in Java

Control structures that repeat a block of code as long as a specified condition is true.

Conditional Statements

Statements that execute different actions based on whether a specified condition is true.

Data Encapsulation

The bundling of data and methods that operate on that data within a class.

Accessors and Mutators

Methods for getting and setting the values of private instance variables.

Code Reusability

The practice of using existing code for new functions to improve efficiency.

Functionality Testing

Validation process to ensure that a piece of software functions as intended.

Performance Testing

Assessment of the speed and responsiveness of a program.

Usability Testing

Evaluating a product by testing it with real users.

Systematic Testing

An organized method to test software to find defects.

Version Control Systems

Tools for managing changes to source code over time.

Code Review Process

A systematic examination of computer source code.
