Java multi-threaded programming: a powerful tool to improve program performance

Multithreaded programming has become an important development technique in modern computer applications. By leveraging multi-threading, we can perform multiple tasks simultaneously, thereby improving the performance and responsiveness of our program. This article will introduce the basic concepts and common techniques of multi-threaded programming in Java, and provide corresponding source code examples.

1. Two ways to create threads

In Java, we can create threads in two ways: inheriting the Thread class and implementing the Runnable interface. Here is sample code for both ways:

// 继承Thread类
class MyThread extends Thread {
   
    
    
    public void run() {
   
    
    
        // 线程执行的代码
    }
}
