ChillDev Commons Concurrent: Multi -threaded tone strategy analysis in the Java class library
CHILLDEV Commons Concurrent: Multi -threaded tone strategy analysis in class libraries of Java
Multi -threaded programming in Java language has become an important part of today's software development.However, thread scheduling is critical to ensure the performance and correctness of the multi -threaded program.To solve this problem, ChillDev Commons Concurrent library provides a set of powerful and flexible multi -threaded tone strategies.
ChillDev Commons Concurrent is an open source Java class library, which aims to enhance the ability of Java concurrent programming.It provides a series of multi -threading strategies for developers to better control and optimize the implementation of multi -threaded programs.
In this article, we will explore some commonly used multi -threading strategies in ChillDev Commons Concurrent libraries.We will explain the working principles of each strategy and provide some code examples suitable for Java to help readers better understand and apply these strategies.
1. FIFO (advanced first) dispatch strategy
FIFO is one of the simplest multi -tone strategies.Under this strategy, when multiple threads compete at the same time, the system will line up in line in the order of threads.Once the resources are available, you will choose a thread in the order of the queue.
Here are a Java code example using FIFO scheduling strategy:
import chilldev.commons.concurrent.strategy.FifoStrategy;
import chilldev.commons.concurrent.strategy.StrategyExecutor;
public class FifoExample {
public static void main(String[] args) {
// Create FIFOSTRATEGY object
FifoStrategy strategy = new FifoStrategy();
// Create the StrategyExecutor object and set the scheduling strategy
StrategyExecutor executor = new StrategyExecutor(strategy);
// Add tasks that need to be executed
executor.addTask(() -> {
System.out.println("Task 1 executed");
});
executor.addTask(() -> {
System.out.println("Task 2 executed");
});
// Start the actuator
executor.start();
}
}
In the above example, we created an instance of FIFO strategy and passed it to the constructor of the StrategyExecutor class.Then, we add the task we need to execute to the actuator and start the execution by calling the `Start ()" method.
2. Priority dispatching strategy
Priority scheduling strategy allows developers to schedule threads based on the priority of the task.The task with higher priority will be performed first, and tasks with lower priority will be waited.
The following is an example of Java code that uses priority scheduling strategies:
import chilldev.commons.concurrent.strategy.PriorityStrategy;
import chilldev.commons.concurrent.strategy.StrategyExecutor;
import chilldev.commons.concurrent.strategy.TaskPriority;
public class PriorityExample {
public static void main(String[] args) {
// Create PriorityStrategy objects
PriorityStrategy strategy = new PriorityStrategy();
// Create the StrategyExecutor object and set the scheduling strategy
StrategyExecutor executor = new StrategyExecutor(strategy);
// Add tasks that need to be executed, and specify the priority of the task
executor.addTask(() -> {
System.out.println("High priority task executed");
}, TaskPriority.HIGH);
executor.addTask(() -> {
System.out.println("Low priority task executed");
}, TaskPriority.LOW);
// Start the actuator
executor.start();
}
}
In the above examples, we first created a PriorityStrategy instance and passed it to the constructor to StrategyExecutor.Then, we add the task we need to perform to the actuator and specify the priority (high or low) for each task.Finally, we call the `start () method to start the execution.
Third, custom scheduling strategy
In addition to the scheduling strategy mentioned above, ChillDev Commons Concurrent library also allows developers to customize the scheduling strategy.By inheriting the `ABSTRACTSTRATEGY` class and implementing the method of` Execute () `, developers can customize the scheduling logic according to their needs.
The following is a Java code example with a custom scheduling strategy:
import chilldev.commons.concurrent.strategy.AbstractStrategy;
import chilldev.commons.concurrent.strategy.StrategyExecutor;
public class CustomStrategy extends AbstractStrategy {
@Override
protected void execute(StrategyExecutor executor) {
// Custom scheduling logic
System.out.println("Custom strategy executed");
executor.executeTasks();
}
}
public class CustomExample {
public static void main(String[] args) {
// Create CustomStrategy object
CustomStrategy strategy = new CustomStrategy();
// Create the StrategyExecutor object and set the scheduling strategy
StrategyExecutor executor = new StrategyExecutor(strategy);
// Add tasks that need to be executed
executor.addTask(() -> {
System.out.println("Task 1 executed");
});
executor.addTask(() -> {
System.out.println("Task 2 executed");
});
// Start the actuator
executor.start();
}
}
In the above example, we created a Customstrategy instance and passed it to the congegyexecutor constructor.We also define our scheduling logic and store in the method of `Execute ().Finally, we add the task we need to execute to the actuator and start the execution by calling the `Start ()" method.
ChillDev Commons Concurrent library provides strong support for Java multi -threaded programming. Its multi -threaded tone strategy can help developers better control and optimize the execution of multi -threaded programs.Regardless of the use of FIFO, priority, or custom strategy, developers can choose the appropriate scheduling strategy according to their needs, and use the interface provided by the library for use and integration.
I hope this article will help you understand the multi -threading strategy in the ChillDev Commons Concurrent Library!
