Methods Summary
public static voidmain(java.lang.String[] ap)
Simple test case

		byte b[] = new byte[10];
		System.out.println("Creating Intr");
		Intr me = new Intr(2000);
		System.out.println("Starting read");
		for (int i=1; i<=5; i++) {
			try {
				// This read will block, unless you type something in
				// the console window (and you have to be pretty quick!).
				int n = System.in.read(b);
				System.out.print(">> ");
				for (int j=0; j<n; j++) {
					if (b[j] == '\n" || b[j] == '\r")
						break;
					System.out.print((char)b[j]);
				}
				System.out.println(" <<");
				if (b[0] == (byte)'Q")
					return;

			} catch (java.io.InterruptedIOException e) {
				System.out.println("Interrupted IO");
			} catch (Exception e) {
				// Other exceptions are more painful
				System.out.println("Caught " + e);
			}
		}
		me.timedThread = null;
		System.out.println("All done");
public voidrun()

		while (timedThread != null) {

				return;
			// if we are still here, the timer went off, but the
			// main program hasn't nullified the thread yet.
