Java线程中的语法错误

我正在学习Java中的线程启动教程。代码是非常基本的Java线程中的语法错误

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()); 
    } 
}

但我得到一个解析错误在这行亚军=新主题（这一点，threadName）;

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

我在这里使用相同的代码http://www.javabeginner.com/learn-java/java-threads-tutorial

我搜索了这个错误，但无法找到任何东西。

在此先感谢
