Extending the Thread class

One way to create a thread is to extend the java.lang.Thread class and override its run() method. Here’s an example of this:

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: " +
