Suppose we have the following code: public class Foo { public Foo() { ... } public void first() { ... } public void second() { ... } public void third() { ... } } The same instance of Foo will be passed to three different threads. ThreadA will call first, threads will call second, and thread( will call third. Design a mechanism to ensure that first is called before second and second is called before third.
