How do you specify thread parameters in Java?

In Java, you can specify the parameters of a thread using the constructor of the Thread class. The constructor of the Thread class has the following forms:

1. Create a new thread object without specifying any parameters.
2. Create a new thread object and specify the target object to be run.
3. Create a new thread object, specifying the target object to be executed and the name of the thread.
4. Creates a new thread object with a specified name.

Here is the example code:

public class MyThread implements Runnable {
    public void run() {
        // 线程执行的代码
    }
}

public class Main {
    public static void main(String[] args) {
        // 创建一个新的线程对象，并指定要运行的目标对象
        Thread thread = new Thread(new MyThread());
        
        // 设置线程的名称
        thread.setName("MyThread");
        
        // 启动线程
        thread.start();
    }
}

In the example above, we specified the target object to be run by the Thread class constructor and set a name for the thread using the setName method. We then called the start method to start the thread.
