Question

I am following a starting tutorial for Threading in Java.
The code is very basic

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());
    }
}

But I get a parsing error in this line
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

I am using the same code here http://www.javabeginner.com/learn-java/java-threads-tutorial

I searched for this error but couldn’t find anything.

Thanks in advance

Delete your own definition of Runnable interface
