Attempt 1: Use AtomicInteger and while loops

class Foo {

    private AtomicInteger num;

    public Foo() {
        num = new AtomicInteger(0);
    }

    public void first(Runnable printFirst) throws InterruptedException {
        printFirst.run();

        num.incrementAndGet();
    }

    public void second(Runnable printSecond) throws InterruptedException {
        while (num.get() != 1) {}

        printSecond.run();

        num.incrementAndGet();
    }

    public void third(Runnable printThird) throws InterruptedException {
        while (num.get() != 2) {}

        printThird.run();
