Problem with Iterator class

I have created a class 'Gerbil' and then created a hash set of the same class in class 'Program
-----------------------------------------
class Gerbli
{
//Contents of class
}
class Program
{
Set<Gerbil> hs = new HashSet<Gerbil>();

void addtoHashSet(Gerbil obj)
{
hs.add(obj);
}

void get()
{
Iterator itr = hs.iterator();
while(itr.hasNext())
{
Gerbil obj=itr.next();//--->ERROR

}
}

}

------------------------
but while compiling the code, the compiler is giving an error at statement

Gerbil obj=itr.next();


Error: incompatible types
found : java.lang.Object
required: Gerbil

-------------------------

But when I tried with 'getClass' method on itr.next(), it returns 'Gerbil class'


Messed:confused:
Please help:mad:
Thanks!!!

Don't use an Iterator object; use an Iterator<Gerbil> object; the first object is a 'raw' object and returns Object type objects; the second one returns Gerbil type objects.

kind regards,

Your iterator is not typed so Java won't let you just assume that it's going to give Gerbli type objects. Better type it with

Code:

---

Iterator<Gerbli> itr = hs.iterator();

---

Your spelling also looks suspicious. Is it Gerbil or Gerbli?

... and Jos is sneaky ...

worked. Thanks for the help.

By the way it's Gerbil. At top, I misspelled it.
