Java Concurrency Patterns

+

A comprehensive collection of concurrency patterns and anti-patterns for Java

+
+ +
+ ๐Ÿ“š API Documentation + ๐Ÿ“– GitHub Repository + ๐Ÿ“Š Test Coverage +
+ +
+

๐ŸŽฏ Overview

+

This library provides a comprehensive collection of concurrency patterns and anti-patterns implemented in Java 21+. + It includes both traditional concurrency mechanisms and modern features like Virtual Threads and Structured Concurrency.

+
+ +
+

๐Ÿš€ Featured Patterns

+
+
+

Virtual Threads

+

Lightweight threads (Project Loom) for massive concurrency with minimal overhead.

+
+
+

Structured Concurrency

+

Treats groups of related tasks as a single unit of work with streamlined error handling.

+
+
+

Leader-Follower Pattern

+

Efficient thread pool where one leader waits for events while followers wait to be promoted.

+
+
+

Thread-Safe Builder

+

Safe construction of objects in concurrent environments with proper synchronization.

+
+
+

Object Pool Pattern

+

Thread-safe object pool for managing reusable resources efficiently.

+
+
+

Producer-Consumer Variations

+

Multiple implementations using different blocking queue types.

+
+
+
+ +
+

โš ๏ธ Anti-Patterns

+

Learn from common concurrency mistakes and their solutions:

+
    +
  • Race Conditions - Uncontrolled access to shared resources
    • +
  • Deadlocks - Circular dependencies in resource acquisition
    • +
  • Thread Leakage - Unmanaged thread lifecycle
    • +
  • Busy Waiting - Inefficient polling mechanisms
    • +
  • Forgotten Synchronization - Missing thread safety
    • +
+
+ +
+

๐Ÿ”ง Requirements

+
    +
  • Java 21 or higher - For modern features like Virtual Threads
    • +
  • Java 8 or higher - For basic patterns only
    • +

Java Concurrency Patterns

A comprehensive collection of concurrency patterns and anti-patterns for Java

-

๐ŸŽฏ Overview

-

This library provides a comprehensive collection of concurrency patterns and anti-patterns implemented in Java 21+. - It includes both traditional concurrency mechanisms and modern features like Virtual Threads and Structured Concurrency.

-
- -
-

๐Ÿš€ Featured Patterns

-
-
-

Virtual Threads

-

Lightweight threads (Project Loom) for massive concurrency with minimal overhead.

-
-
-

Structured Concurrency

-

Treats groups of related tasks as a single unit of work with streamlined error handling.

-
-
-

Leader-Follower Pattern

-

Efficient thread pool where one leader waits for events while followers wait to be promoted.

-
-
-

Thread-Safe Builder

-

Safe construction of objects in concurrent environments with proper synchronization.

-
-
-

Object Pool Pattern

-

Thread-safe object pool for managing reusable resources efficiently.

-
-
-

Producer-Consumer Variations

-

Multiple implementations using different blocking queue types.

-
-
-
- -
-

โš ๏ธ Anti-Patterns

-

Learn from common concurrency mistakes and their solutions:

-
    -
  • Race Conditions - Uncontrolled access to shared resources
    • -
  • Deadlocks - Circular dependencies in resource acquisition
    • -
  • Thread Leakage - Unmanaged thread lifecycle
    • -
  • Busy Waiting - Inefficient polling mechanisms
    • -
  • Forgotten Synchronization - Missing thread safety
    • -
-
- -
-

๐Ÿ”ง Requirements

-
    -
  • Java 21 or higher - For modern features like Virtual Threads
    • -
  • Java 8 or higher - For basic patterns only
    • -

๐ŸŽฏ Overview

+#

This library provides a comprehensive collection of concurrency patterns and anti-patterns implemented in Java 21+. +# It includes both traditional concurrency mechanisms and modern features like Virtual Threads and Structured Concurrency.

+#
+# +#
+#

๐Ÿš€ Featured Patterns

+#
+#
+#

Virtual Threads

+#

Lightweight threads (Project Loom) for massive concurrency with minimal overhead.

+#
+#
+#

Structured Concurrency

+#

Treats groups of related tasks as a single unit of work with streamlined error handling.

+#
+#
+#

Leader-Follower Pattern

+#

Efficient thread pool where one leader waits for events while followers wait to be promoted.

+#
+#
+#

Thread-Safe Builder

+#

Safe construction of objects in concurrent environments with proper synchronization.

+#
+#
+#

Object Pool Pattern

+#

Thread-safe object pool for managing reusable resources efficiently.

+#
+#
+#

Producer-Consumer Variations

+#

Multiple implementations using different blocking queue types.

+#
+#
+#
+# +#
+#

โš ๏ธ Anti-Patterns

+#

Learn from common concurrency mistakes and their solutions:

+#
    +#
  • Race Conditions - Uncontrolled access to shared resources
    • +#
  • Deadlocks - Circular dependencies in resource acquisition
    • +#
  • Thread Leakage - Unmanaged thread lifecycle
    • +#
  • Busy Waiting - Inefficient polling mechanisms
    • +#
  • Forgotten Synchronization - Missing thread safety
    • +#
+#
+# +#
+#

๐Ÿ”ง Requirements

+#
    +#
  • Java 21 or higher - For modern features like Virtual Threads
    • +#
  • Java 8 or higher - For basic patterns only
    • +#
