guice

Consider this simple example.

Class A {
   B b;
   A() {
       this.b = new B(this);
   }
}

In this example instance A knows about instance B, and instance B knows about instance A.

My question is: how to instantiate instance A with Guice, i.e. how to make Guice take care of this complex circle dependencies?
