Java線程中的語法錯誤

我正在學習Java中的線程啓動教程。代碼是非常基本的Java線程中的語法錯誤

public interface Runnable { 

void run(); 

} 

public class RunnableThread implements Runnable { 

    Thread runner; 
    public RunnableThread() { 
    } 
    public RunnableThread(String threadName) { 
     runner = new Thread(this, threadName); // (1) Create a new thread. 
     System.out.println(runner.getName()); 
     runner.start(); // (2) Start the thread. 
    } 
    public void run() { 
     //Display info about this particular thread 
     System.out.println(Thread.currentThread()); 
    } 
}

但我得到一個解析錯誤在這行亞軍=新主題（這一點，threadName）;

no suitable constructor found for Thread(RunnableThread,java.lang.String)

我在這裏使用相同的代碼http://www.javabeginner.com/learn-java/java-threads-tutorial

我搜索了這個錯誤，但無法找到任何東西。

在此先感謝
