Java Thread Creation Using Thread Class

In Java, creating a thread using the Thread class can be achieved by following these steps:

1. Create a class that extends the Thread class, override the run() method, and write the thread’s execution logic within the run() method.

public class MyThread extends Thread {
    @Override
    public void run() {
        // 线程执行逻辑
        System.out.println("Hello, I am a thread!");
    }
}

1. Create a thread object in the main program and call the start() method to start the thread.

public class Main {
    public static void main(String[] args) {
        MyThread myThread = new MyThread();
        myThread.start();
    }
}

By following the steps above, you can create a thread using the Thread class and execute the thread logic. It is important to note that a thread object can only call the start() method once to start the thread, as calling it again will result in an IllegalThreadStateException being thrown.
