Java线程中的语法错误

Question

我正在学习Java中的线程入门教程.代码非常基础

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());
    }
}

但是我在这个行中获得了一个解析错误:runner = new Thread(this,threadName);

   no suitable constructor found for Thread(RunnableThread,java.lang.String)
constructor java.lang.Thread.Thread(java.lang.ThreadGroup,java.lang.Runnable,java.lang.String,long) is not applicable
  (actual and formal argument lists differ in length)

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找不到任何东西.

您已经创建了自己的Runnable接口.我建议你删除它以避免混淆.
