Is a plain "void method()" public, protected or private by default?

No. Unfortunately, Sun chose not to allow use of a keyword for the
fourth access mode, "default access", which is really package access.

Patricia

so it's basically private?

No, it is 'none of the above'. It means 'accessible to all classes
within the same package'. As it says in the post you quoted and the link
cited therein.

So what's this ThreadGroup method available to?:

/**
     * Adds the specified Thread to this group.
     * @param t the Thread to be added
     * @exception IllegalThreadStateException If the Thread group has been
destroyed.
     */
    void add(Thread t) {
    synchronized (this) {
        if (destroyed) {
        throw new IllegalThreadStateException();
        }
        if (threads == null) {
        threads = new Thread[4];
        } else if (nthreads == threads.length) {
        Thread newthreads[] = new Thread[nthreads * 2];
        System.arraycopy(threads, 0, newthreads, 0, nthreads);
        threads = newthreads;
        }
        threads[nthreads] = t;

        // This is done last so it doesn't matter in case the
        // thread is killed
        nthreads++;
            nUnstartedThreads--;
    }
    }
