Factory Method

Defines an interface for creating an object but lets subclasses decide which concrete class to instantiate, deferring instantiation to subclasses.

Abstract Factory

Provides an interface for creating families of related objects without specifying their concrete classes, ensuring products from one family are used together.

Builder

Separates the construction of a complex object from its representation so the same construction process can create different representations step by step.

Prototype

Creates new objects by cloning an existing instance (the prototype) rather than instantiating a class, useful when construction is costly or types are decided at runtime.

Singleton

Ensures a class has only one instance and provides a global point of access to it, used for shared resources like configuration, logging, or connection pools.

Lazy Initialization

Defers the creation or computation of an object until the first time it is actually needed, avoiding upfront cost for resources that may never be used.

Multiton

Generalizes Singleton to manage a fixed, keyed set of named instances, ensuring exactly one instance exists per key through a registry.

Registry

Provides a well-known central object where shared instances or services can be registered and looked up by key, giving a single point of access without scattered globals.

Adapter

Converts the interface of a class into another interface clients expect, letting classes that could not otherwise collaborate work together.

Bridge

Decouples an abstraction from its implementation so the two can vary independently, avoiding a combinatorial explosion of subclasses.

Composite

Composes objects into tree structures to represent part-whole hierarchies, letting clients treat individual objects and compositions uniformly.

Decorator

Attaches additional responsibilities to an object dynamically by wrapping it, providing a flexible alternative to subclassing for extending behavior.

Flyweight

Minimizes memory use by sharing as much data as possible between many similar objects, separating intrinsic shared state from extrinsic context-specific state.

Proxy

Provides a surrogate or placeholder for another object to control access to it, enabling lazy loading, access control, caching, or remote access.

Module

Encapsulates related code into a single self-contained unit with a controlled public interface and hidden private state, organizing code and avoiding global namespace pollution.

Marker Interface

Uses an empty interface to tag a class with metadata so other code can detect the capability at runtime via type checks, without adding any methods.

Mixin

Composes reusable units of behavior into a class without inheritance, letting unrelated classes share functionality by mixing in shared method sets.

Extension Object

Lets you add new interfaces and behavior to a class over time without changing it, by attaching extension objects that clients query for at runtime.

Private Class Data

Restricts accessor-write access to class attributes by isolating data in a separate object exposed read-only after construction, enforcing immutability and encapsulation.

Producer-Consumer

A concurrency pattern where producers place work on a shared bounded queue and consumers process it independently, decoupling rates and smoothing load.

Thread Pool

A concurrency pattern that reuses a fixed set of worker threads to execute many tasks, avoiding per-task thread creation cost and bounding concurrency.

Actor Model

A concurrency model where independent actors encapsulate state and communicate only by asynchronous messages, avoiding shared memory and locks.

Reactor

An event-handling pattern that demultiplexes I/O events on one or few threads and dispatches them synchronously to registered handlers, enabling scalable non-blocking servers.

What is the difference between compiled and interpreted languages?

A compiled language is translated ahead of time into machine code by a compiler, producing a standalone executable that the CPU runs directly—languages like C, Go, and Rust work this way and tend to run fast. An interpreted language is executed line by line at runtime by an interpreter, as with classic Python or Ruby, which trades some speed for flexibility and faster iteration. The line is blurry: many modern languages, such as Java and C#, compile to bytecode that a virtual machine then interprets or just-in-time compiles. The distinction is really about implementation, not the language itself.

What is type safety?

Type safety is the degree to which a programming language prevents type errors—operations applied to values of the wrong type, like adding a number to a function. Statically typed languages such as Java, Go, and TypeScript check types at compile time, catching many mistakes before the code runs. Dynamically typed languages such as Python and JavaScript check types at runtime, offering more flexibility but deferring errors until execution. Stronger type safety generally improves reliability and tooling support at the cost of some upfront strictness.

What is the difference between imperative and declarative programming?

Imperative programming describes how to achieve a result through explicit step-by-step instructions that change program state, as in a typical for-loop that mutates a counter. Declarative programming describes what result you want and lets the system figure out how, as in SQL queries, HTML, or functional operations like map and filter. Declarative code is often more concise and easier to reason about, while imperative code gives finer control over execution. Many languages and tools blend both styles depending on the problem.
