Object-Oriented Programming Review

These flashcards cover essential concepts and terminologies in Object-Oriented Programming, specifically focusing on Java.

What are the key characteristics of Java?

Java is simple, object-oriented, distributed, interpreted, robust, secure, architecture-neutral, portable, has good performance, is multithreaded, and dynamic.

What does encapsulation mean in OOP?

Encapsulation is the principle of bundling the data and the methods that operate on that data into a single unit or class, while restricting access to some of the object's components.

What is polymorphism in OOP?

Polymorphism allows methods to do different things based on the object it is acting upon, enabling a single method name to be used for different types.

What is inheritance in Java?

Inheritance is a mechanism where one class acquires the properties (fields and methods) of another class, facilitating code reuse and organization.

Define algorithms in the context of programming.

An algorithm is a set of instructions for solving a problem or performing an action, expressed completely and precisely.

What are the three kinds of programming errors?

The three kinds of programming errors are: Syntax errors, runtime errors, and logic errors.

How does Java ensure portability of applications?

Java applications are portable because they are compiled into bytecode that can run on any platform with a Java Virtual Machine (JVM).

What is the purpose of comments in Java programming?

Comments are used to explain and clarify the code, making it more understandable for others and for the developer when revisiting the code later.

What are common naming conventions for Java classes?

Common conventions include using PascalCase where each word starts with an uppercase letter, e.g., ComputeExpression.

What is the function of the main method in Java?
