Analysis of the application case analysis of the low -delayed primitive concurrency queue in the java class library
Summary:
The low-delayed original concurrent queue is a data structure for thread communication. It provides efficient producers-consumer model that can achieve rapid data transmission in multi-threaded applications.This article will introduce the low -delayed original concurrency queue in the Java class library, and analyze its application in different scenarios through actual case analysis.
1 Introduction
Low -delayed thread inter -thread communication is one of the key needs in many concurrent applications.The Java class library provides the original complication queue.These queues have achieved high throughput and low-delayed data transmission through no locking and blocking design, which is suitable for fast producers-consumer models.
2. ConcurrentLinkedQueue
ConcurrentlinkedQueue is a non -blocking thread security queue in the Java class library that implements the linked list -based advanced FIFO (FIFO) strategy.It is suitable for highly concurrent scenes and provides good horizontal scalability.The following code shows the basic usage of ConcurrentlinkedQueue:
import java.util.Queue;
import java.util.concurrent.ConcurrentLinkedQueue;
public class ConcurrentLinkedQueueExample {
public static void main(String[] args) {
Queue<String> queue = new ConcurrentLinkedQueue<>();
// Add elements to the producer thread to the queue
Thread producer = new Thread(() -> {
for (int i = 0; i < 10; i++) {
queue.offer("Element " + i);
}
});
// Take the element from the queue from the queue
Thread consumer = new Thread(() -> {
while (!queue.isEmpty()) {
System.out.println(queue.poll());
}
});
producer.start();
consumer.start();
}
}
3. LinkedTransferQueue
LinkedTransferqueue is a higher -level unlimited blocking queue in the Java class library. It expands ConcurrentLinkedQueue and provides more powerful features.Unlike ConcurrentlinkedQueue, the elements of LinkedTransferqueue can wait for consumers to obtain immediately when adding.The following code shows the basic usage of LinkedTransferqueue:
import java.util.concurrent.LinkedTransferQueue;
public class LinkedTransferQueueExample {
public static void main(String[] args) throws InterruptedException {
LinkedTransferQueue<String> queue = new LinkedTransferQueue<>();
// Add elements to the producer thread to the queue
Thread producer = new Thread(() -> {
try {
for (int i = 0; i < 10; i++) {
queue.transfer("Element " + i);
}
} catch (InterruptedException e) {
e.printStackTrace();
}
});
// Take the element from the queue from the queue
Thread consumer = new Thread(() -> {
try {
while (true) {
String element = queue.take();
System.out.println(element);
}
} catch (InterruptedException e) {
e.printStackTrace();
}
});
producer.start();
consumer.start();
// After waiting for a period of time to stop the producer thread
Thread.sleep(1000);
producer.interrupt();
}
}
4. Application case analysis
Low delayed original concurrent queue has high value in the following application scenarios:
-The thread pool task scheduling: The use of the original concurrent queue as the task queue can reduce the delay between the task submission and execution.
-D asynchronous message processing: By putting the message in the original concurrent queue, the message can be passed to consumers quickly to achieve efficient asynchronous message processing.
-Setically data flow processing: Put the data generated in real time into the original concurrent queue. The consumer thread can immediately obtain the data and process it to achieve real -time data flow processing.
in conclusion:
The low -delayed original concurrent queue is a very useful tool in the Java class library that can help developers to achieve efficient thread intercate communication.By using ConcurrentLinkedQueue and Linkedtransferqueue, fast data transmission and low -delayed data processing can be achieved in multi -threaded applications.In the appropriate application scenario, the use of low -delayed original concurrent queues can significantly improve the performance and response ability of the system.
