The function application case of the Israfil Foundation Class Class Framework in the Java class library
Overview:
The Israfil Foundation Class Class Framework is a concurrent programming framework widely used in the Java class library.It provides a set of powerful categories and tools for solving common problems in concurrent design.This article will introduce some functional application cases of the ISRAFIL Foundation Class Class Framework and related Java code examples.
1. Thread synchronization: In concurrent programming, thread synchronization is an important problem.The ISRAFIL Foundation Category Framework provides various synchronization mechanisms, such as Mutex, semaphore, and barrier.The following is an example of a simple thread synchronization using mutual locks:
import israfil.foundation.concurrency.Mutex;
public class SynchronizedThread implements Runnable {
private static Mutex mutex = new Mutex();
public void run() {
mutex.lock();
try {
// Thread synchronization area
// ...
} finally {
mutex.unlock();
}
}
public static void main(String[] args) {
// Create multiple threads
Thread thread1 = new Thread(new SynchronizedThread());
Thread thread2 = new Thread(new SynchronizedThread());
// Starting thread
thread1.start();
thread2.start();
}
}
2. Thread communication: Before introducing thread communication, you must first understand the important mechanism of the ISRAFIL Foundation concurrent class framework -event (Event).Event is the basis of communication between threads and is used to send and receive signals.The following is an example of a thread communication with events:
import israfil.foundation.concurrency.EventQueue;
import israfil.foundation.concurrency.Event;
public class ThreadCommunication {
public static void main(String[] args) {
// Create an event queue
EventQueue eventQueue = new EventQueue();
// Create a producer thread
Thread producer = new Thread(() -> {
for (int i = 1; i <= 10; i++) {
Event event = new Event(i);
eventQueue.send(event);
}
});
// Create a consumer thread
Thread consumer = new Thread(() -> {
for (int i = 1; i <= 10; i++) {
Event event = eventQueue.receive();
System.out.println("Received event: " + event.getData());
}
});
// Starting thread
producer.start();
consumer.start();
}
}
3. Parallel computing: The ISRAFIL Foundation Class Class Framework also provides a mechanism for performing parallel computing on the multi -nuclear system.The following is an example of using a parallel execution thread for image processing:
import israfil.foundation.concurrency.Parallel;
public class ImageProcessing {
public static void main(String[] args) {
// Load image data
Image image = Image.load("input.jpg");
// Building together
Parallel parallel = new Parallel(image.getHeight());
// Treat each pixel
for (int y = 0; y < image.getHeight(); y++) {
final int row = y;
parallel.execute(() -> {
for (int x = 0; x < image.getWidth(); x++) {
Color color = image.getPixel(x, row);
// Pixel processing logic
// ...
image.setPixel(x, row, color);
}
});
}
// Waiting for all jobs to complete
parallel.waitForCompletion();
// The image after saving
image.save("output.jpg");
}
}
in conclusion:
The ISRAFIL Foundation Class Class Framework in the Java class library is diverse. This article only introduces some common application scenarios.This framework provides powerful functions such as thread synchronization, thread communication and parallel computing, and provides a reliable solution for the design of the concurrent program.If you are developing a parallel application, you may wish to consider using the ISRAFIL Foundation concurrent category framework to simplify the development process and improve the performance and reliability of the program.
