在Java多线程编程中,可以通过实现Runnable接口或继承Thread类来创建线程。为了向线程传递参数,可以使用构造函数或者实例变量。下面是两种方法的示例:

  1. 实现Runnable接口:
class MyRunnable implements Runnable {
    private String param;

    public MyRunnable(String param) {
        this.param = param;
    }

    @Override
    public void run() {
        System.out.println("线程参数: " + param);
    }
}

public class Main {
    public static void main(String[] args) {
        String param = "Hello, World!";
        MyRunnable myRunnable = new MyRunnable(param);
        Thread thread = new Thread(myRunnable);
        thread.start();
    }
}
  1. 继承Thread类:
class MyThread extends Thread {
    private String param;

    public MyThread(String param) {
        this.param = param;
    }

    @Override
    public void run() {
        System.out.println("线程参数: " + param);
    }
}

public class Main {
    public static void main(String[] args) {
        String param = "Hello, World!";
        MyThread myThread = new MyThread(param);
        myThread.start();
    }
}

在这两个示例中,我们分别使用构造函数将参数传递给MyRunnable和MyThread类。然后在run()方法中使用这些参数。最后,在主方法中创建线程并启动它。
