ChillDev Commons Concurrent: A concurrent programming foundation in the Java class library
In the field of software development today, the popularity of multi -core processors makes concurrent programming an indispensable part of building high -performance applications.Although concurrent programming brings higher performance and better resource utilization, various challenges have also been introduced, such as race conditions, deadLock, and live locks.In order to help developers better deal with these problems, Java provides a powerful concurrency programming library. Among them, ChillDev Commons Concurrent is a simple and effective concurrent programming solution based on the Java class library.
ChillDev Commons Concurrent is an open source Java class library, which aims to help developers handle concurrent programming in a simpler way.It provides some basic tools and abstraction, so that developers can more easily write complicated and secure code.
The following will introduce some basic functions provided by ChillDev Commons Concurrent and how to use them to handle common problems in concurrent programming.
1. Lock (LOCK) and Condition (Condition)
ChillDev Commons Concurrent provides some simple and easy -to -use locks and conditions to manage mutually exclusive access to sharing resources.By using locks and conditions, only one thread can be modified at the same time at the same time.
import com.chilldev.commons.concurrent.Lock;
import com.chilldev.commons.concurrent.Condition;
Lock lock = new Lock();
Condition condition = lock.newCondition();
// Thread 1 Get the lock and modify the shared resources
lock.lock();
try {
// Modify sharing resources
condition.signal (); // The thread waiting for waiting
} finally {
lock.unlock (); // Release the lock
}
// Thread 2 Waiting Thread 1 Modify Sharing Resources
lock.lock();
try {
while (!condition.isSignaled()) {
condition.await (); // Waiting for notification
}
// The shared resource has been modified and can continue to be executed
} finally {
lock.unlock (); // Release the lock
}
2. ReadwriteLock
In order to improve performance, ChillDev Commons Concurrent also provides read and write locks.Reading and writing locks allow multiple threads to read shared resources at the same time, but only one thread is allowed to write shared resources.
import com.chilldev.commons.concurrent.ReadWriteLock;
ReadWriteLock rwLock = new ReadWriteLock();
// Get reading locks
rwLock.readLock().lock();
try {
// Execute reading operation
} finally {
rwLock.readLock().unlock();
}
// Get writing locks
rwLock.writeLock().lock();
try {
// Execute the writing operation
} finally {
rwLock.writeLock().unlock();
}
3. Equipment
ChillDev Commons Concurrent provides some complicated sets, such as ConcurrenThashSet and ConcurrenThashMap.These concurrent sets allow multiple threads to access and modify the elements in the set at the same time without explicit synchronization control.
import com.chilldev.commons.concurrent.collection.ConcurrentHashSet;
ConcurrentHashSet<String> set = new ConcurrentHashSet<>();
set.add("hello");
set.add("world");
System.out.println(set.contains("hello")); // true
System.out.println(set.size()); // 2
ChillDev Commons Concurrent also provides many other functions, such as atomic operations, concurrent task scheduling, and concurrent tools, which can be used according to specific needs.
In concurrent programming, it is crucial to properly handle the access to shared resources.Using ChillDev Commons Concurrent, developers can more easily write complicated code to avoid some common concurrent problems.By using the concurrent programming foundation in the Java library, developers can better cope with the challenges brought by multi -core processors and build high -performance and reliable applications.
