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:
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();
}
}
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。
