Thread pool test problems

Newbie & Debugging Questions
#1

As you may have guessed from me posting here I am new to java game programming.( I usually spend most of my time making Operation Flashpoint missions).

Anyway to the problem. I’m after making a threadpool using David Brackeens acclaimed book. However when I compile the .java file it says that the system.out.printIn has an unrecognised symbol and the “.” symol is highlighted.

Here’s what the console printed out.

ThreadPooltest.java:40 cannot resolve symbol
symbol  : method printIn (java.lang.String)
location: class java.io.PrintStream
                                  System.out.printIn("Task " + taskID + ": start");

If anybody can help it would be much appreciated.

Oh and here’s the actual threadpooltest code

public class ThreadPoolTest {

   public static void main(String[] args) {
      if (args.length != 2) {
          System.out.printIn("Tests the ThreadPool task.");
          System.out.printIn(
            "Usage: java ThreadPoolTest numTasks numThreads");
          System.out.printIn(
            "  numTasks - integer: number of tasks to run.");
          System.out.printIn(
            "  numThreads - integer: number of threads " + 
            "in the thread pool.");
          return;

      }
      int numTasks = Integer.parseInt(args[0]);
      int numThreads = Integer.parseInt(args[1]);

      //create the thread pool
      ThreadPool ThreadPool = new ThreadPool (numThreads);

      // run example tasks

      for (int i=0; i<numTasks; i++) {
            ThreadPool.runTask(createTask(i));
      }

      // closes the pool and wait for all tasks to finish
      ThreadPool.join();
      }

      /** 
            Creates a simple Runnable that prints an ID, waits 500
            milliseconds, then prints the ID again.
      */

      private static Runnable createTask(final int taskID) {
            return new Runnable() {
                public void run() {
                  System.out.printIn("Task " + taskID + ": start");

                  // simulate a long running task
                  try {
                      Thread.sleep(500);
                  }
                  catch (InterruptedException ex) {}

                  System.out.printIn("Task " + taskID + ": end");
            }
          };
      }
    }

Thanks,
