The question is how many references we have to a specified Java Object. The
following code illustrates the idea:
Double d1 = new Double(1.2);
{
Double d2 = d1;
// Now we have two references to the same object.
getRefCount(d1); // Must return 2
}
getRefCount(d1); // Must return 1
So we need a function like getRefCount(Object o)
