      Description

      If the constructor has a void in front of it, the java compiler doesnt recognize the
      constructor at all. Here is the example (with ==> pointer where defn) and output:

      // Destroying a thread.

      import java.io.PipedOutputStream;
      import java.io.PipedInputStream;

      class speaker extends Thread {
        private int speakerNumber;

      ==> public void speaker(int i, PipedOutputStream b, PipedInputStream c) {
          speakerNumber = i;
        }

        public void run() {
          int i = 0;

          if (speakerNumber == 1)
            stop();
          while(++i < speakerNumber)
            System.out.println("Hello World #" + speakerNumber);
        }
      }

      class demo {
        public static void main(String args[]) {
          speaker speaker1, speaker2;
          PipedOutputStream pout;
          PipedInputStream pin;

          pout = new PipedOutputStream();
          pin = new PipedInputStream();

          speaker1 = new speaker(1, pout, pin);
          speaker1.start();
          speaker2 = new speaker(2, pout, pin);
          speaker2.start();
        }
      }

      Output:
      ======
      [124][tmp] ? javac threads.java
      threads.java:32: No constructor matching speaker(int, java.io.PipedOutputStream, java.io.PipedInputStream) found in class speaker.
