Using the practical guide to the IsraFil Foundation of the Java Library
introduce:
The Israfil Foundation is a Java class library that provides a powerful class and interface for concurrent programming.This guide will take you to understand the concurrent framework of the ISRAFIL Foundation, and provide practical guidelines and example code to help you develop highly efficient and reliable concurrent applications.
1. Equipment programming summary:
Concurrent programming is a technology that writes multi -threaded applications, which can more fully use the computer's multi -core processor and resources.However, concurrent programming also brings some challenges, such as thread security, sharing resource management and deadlock.
2. Israfil Foundation:
The Israfil Foundation provides rich class and interfaces for processing various challenges in concurrent programming.Some of these important classes include:
-THREADPOOL: Manage the thread pool, reuse threads, and limit the number of concurrent threads.
-Countdownlatch: Implement a counter that allows one or more threads to wait for other threads to complete.
-SEMAPHORE: Implement the number of accesses of access to public resources.
-CyclicBarrier: To achieve a cycle barrier, all threads must reach the barrier point to continue to execute.
-LOCK and Condition: Provide more fine -grained thread synchronization and mutual exclusion.
-CONCURRENTMAP: The thread-safe key-value mapping, supporting concurrent access.
3. Practical guide:
Here are some practical guidelines for using the Israfil Foundation:
3.1 Use thread pool:
The use of the ThreadPool class can manage the thread pool and reuse threads to avoid the overhead brought by frequent creation and destruction of threads.The following is a simple example:
ExecutorService executor = Executors.newFixedThreadPool(5);
for (int i = 0; i < 10; i++) {
Runnable worker = new MyRunnable();
executor.execute(worker);
}
executor.shutdown();
3.2 thread synchronization and mutual exclusion:
Using the Lock and Condition classes can achieve a finer granular thread synchronization and mutual exclusion.The following is an example:
Lock lock = new ReentrantLock();
Condition condition = lock.newCondition();
// thread 1
lock.lock();
try {
while (!conditionIsMet()) {
condition.await();
}
performAction();
condition.signalAll();
} finally {
lock.unlock();
}
// thread 2
lock.lock();
try {
condition.signalAll();
} finally {
lock.unlock();
}
3.3 Using Semaphore:
The Semaphore class implements the signal number, which can limit the number of accesses of public resources.The following is an example:
Semaphore semaphore = new Semaphore(3);
// thread 1
semaphore.acquire();
try {
accessSharedResource();
} finally {
semaphore.release();
}
// thread 2
semaphore.acquire();
try {
accessSharedResource();
} finally {
semaphore.release();
}
4. Summary:
Using the ISRAFIL Foundation's concurrent framework can better manage threads and resources in the complicated application.This guide provides some practical guidelines and example code to help you start using the Israfil class library to write high -efficiency and reliable complicated applications.
Please note that the above is just some simple examples. The Israfil Foundation provides more functional class and interfaces. You can conduct in -depth research and use according to your needs.
