import java.util.* ?!!

[soumya ravindranath]

Hi,

I just noticed this unexpected behaviour on my system. If I have

import java.util.*;
 
:
:
Set s = new HashSet();
Set hash = new HashSet(s);
 
:

compilation fails with 'cannot resolve symbol' error for HashSet constructor. It even said -

TestHashSet.java:27: incompatible types
found : HashSet
required: java.util.Set
Set s = new HashSet();
^
TestHashSet.java:28: cannot resolve symbol
symbol : constructor HashSet (java.util.Set)
location: class HashSet
Set hash = new HashSet(s);


Compilation succeeds only if I do individual imports for Set and HashSet ( I tried for ArrayList, List, Collection too ).

What am I missing ?!

thanks,
Soumya.

Works fine for me. I'd double check your import statement.

You have defined your own class named "HashSet", and it's on your class path. Even if you've deleted the source code, the .class file is hiding somewhere. Find it, and delete it.

and you are God!

( I did have it from some previous experiment )

I just recognized this symptom from helping other people in the past. This happens to people more often than you would think! Glad I could help.
