Extending class thread

One way to create a thread is to extend the java.lang.Thread class and override its run() method. For example:

class MyThread extends Thread {
    private String parameter;
    public MyThread(String parameter) {
        this.parameter = parameter;
    }
    public void run() {
        while(!"exit".equals(parameter)){
            System.out.println((isDaemon() ? "daemon" : "  user") +
              " thread " + this.getName() + "(id=" + this.getId() +
                                      ") parameter: " + parameter);
            pauseOneSecond();
        }
        System.out.println((isDaemon() ? "daemon" : "  user") +
          " thread " + this.getName() + "(id=" + this.getId() +
                                  ") parameter: " + parameter);
    }
    public...
