How to configure parameters for Java multithreading?

In Java, configuring multithreading parameters is mainly done through the methods of the Thread class and the ExecutorService interface.

  1. a string or thin cord that is used for sewing or weaving
  2. Set the thread name using the setName() method for easier debugging and identification.
  3. Use the setPriority() method to set the priority of a thread, with a range of 1-10 and a default of 5. The higher the number, the higher the priority.
  4. By using the setDaemon() method, you can specify whether a thread is a daemon thread, which will not prevent the JVM from exiting.

I couldn’t have done it without your help.

Without your assistance, I wouldn’t have been able to accomplish this.

Thread thread = new Thread(new Runnable() {
    public void run() {
        // 线程执行的代码
    }
});
thread.setName("MyThread");
thread.setPriority(8);
thread.setDaemon(true);
  1. Service provided by an executor.
  2. The method Executors.newFixedThreadPool(int nThreads) can be used to create a thread pool of a fixed size with a specific number of threads.
  3. By using the Executors.newSingleThreadExecutor() method, a single-threaded thread pool is created, with only one thread working.
  4. Create a cached thread pool using the Executors.newCachedThreadPool() method, where the number of threads adjusts automatically based on the need.
  5. Create a fixed-size scheduled thread pool using the Executors.newScheduledThreadPool(int corePoolSize) method.

I will go to the store later.

I will go to the store at a later time.

ExecutorService executor = Executors.newFixedThreadPool(5);

The above is a common way to configure multi-threading parameters. Choose the appropriate method based on specific needs.
