Object Creation

Why
Collection l = new ArrayList();
is allowed but not
List l = new ArrayList();

[Mike Curwen]

If the error you get is:
l is already defined in [ wherever you've defined it ]

Then your problem is you've used the same variable name twice. Otherwise, I can compile this:

import java.util.*;
public class TestCollection {
public static void main(String args[]) {
TestCollection app = new TestCollection();
app.DoIt();
}
void DoIt() {
Collection c = new ArrayList();
List l = new ArrayList();
}
}
