Howdy,

Maybe I'm still not understanding ;) But why doesn't the instanceof
operator work for you?
Your example:
> java.util.Date date1 = new java.util.Date();
> java.sql.Date date2 = new java.sql.Date();
> Class clasz = date1.getClass();
> if (date2 instanceof clasz)
> {
> do something...

Why not just do
if(date2 instanceof date1) ...
rather than if(date2 instanceof date1.getClass()) ??
Or are you looking for a comparison that doesn't make subclasses equal?
For example:
Set h1 = new LinkedHashSet();
if(h1 instanceof LinkedHashSet) {
// This is true
}
if(h1 instanceof HashSet) {
// This is true
}
if(h1 instanceof Set) {
// This is true
}
But you only want the first one? How about
Object obj1 = new Object1();
Object obj2 = new Object2(); // Object2 extends Object1
if(obj1 instanceof obj1) {
// This is false
}
if(obj2 instanceof ob1) {
// This is true
}
if(obj2.getClass().getName().equals(obj1.getClass().getName()) {
// This is false -- is this what you want?
}
