ChillDev Commons Concurrent: Introduction to Framework, which is often searched in the Java class library
ChillDev Commons Concurrent is a widely popular Java class library that provides developers with some extended concurrent tools and frameworks.This library aims to simplify multi -threaded programming and provide some commonly used operations and modes to facilitate developers to write high -efficiency concurrent code.
ChillDev Commons Concurrent library contains multiple independent modules. Below will introduce some of the frameworks that are often searched and used by developers:
1. Parallelutils: This framework provides a series of tool classes and methods for simplifying the writing and management of parallel tasks.It contains a thread pool manager, task parallel actuator, synchronous auxiliary tool, etc., which can help developers write parallel code easier and make full use of the performance advantages of multi -core processors.
Below is an example code that uses parallelutils to perform parallel tasks:
import chilldev.commons.concurrent.ParallelUtils;
public class ParallelTaskExample {
public static void main(String[] args) {
// Define the task list
List<Runnable> tasks = new ArrayList<>();
tasks.add(() -> System.out.println("Task 1"));
tasks.add(() -> System.out.println("Task 2"));
tasks.add(() -> System.out.println("Task 3"));
// Parallel execution task
ParallelUtils.executeParallel(tasks);
}
}
2. ConcurrentCache: This framework provides a high -performance concurrent cache implementation.It uses ConcurrenThashMap as the underlying data structure, provides a thread -secure cache access and update operation, and supports a regular expiration mechanism.Developers can use CONCURRENTCACHE to cache calculation results, database query results, etc. to improve the response speed and concurrency performance of the system.
Here are a sample code using ConcurrentCache:
import chilldev.commons.concurrent.ConcurrentCache;
public class ConcurrentCacheExample {
public static void main(String[] args) {
ConcurrentCache<String, Integer> cache = new ConcurrentCache<>();
// Cache data
cache.put("key1", 100);
cache.put("key2", 200);
// Obtain data from the cache
System.out.println (cache.get ("key1"); // Output: 100
System.out.println (cache.get ("key2"); // Output: 200
// Delete the data in the cache
cache.remove("key1");
// Check whether the cache contains the specified key
System.out.println (cache.containskey ("key1"); // Output: false
}
}
3. CountdownlatchManager: This framework provides a reusable Countdownlatch manager.Countdownlaatch is a counter in Java packet packets that can be used to synchronize the execution of multiple threads.CountdownlatchManager provides more convenient ways to use and richer features by encapsulation and expansion of the Countdownlatch class.
Below is an example code using countdownlatchmanager:
import chilldev.commons.concurrent.CountDownLatchManager;
public class CountDownLatchManagerExample {
public static void main(String[] args) throws InterruptedException {
CountDownLatchManager manager = new CountDownLatchManager(3);
// Create multiple threads and execute simultaneously
for (int i = 0; i < 3; i++) {
new Thread(() -> {
try {
System.out.println("Thread started");
Thread.sleep(1000);
System.out.println("Thread finished");
} catch (InterruptedException e) {
e.printStackTrace();
} finally {
manager.countDown();
}
}).start();
}
// Waiting for all threads to execute
manager.await();
System.out.println("All threads finished");
}
}
The above introduces some frameworks that are often searched and used in ChillDev Commons Concurrent libraries.These frameworks can help developers more easily write high -efficiency concurrent code to improve the performance and scalability of the system.If you are developing a multi -threaded application, you may wish to consider using ChillDev Commons Concurrent library to simplify your work.
