Syntax error on ArrayList declaration

Question

I've got the following code:

import java.util.*;

public class Group {
    public static void main(String[] args) {
    ArrayList<Integer> list = new ArrayList<Integer>();
    }
}

Eclipse (3.0.0) complains about the ArrayList declaration: syntax error on token "(", on both tokens "<", and then on token "=". I'm using java 1.5.0_07.

What am I doing wrong?

Thanks, regards, Miel.

Set your JDK level to >= 5.0 to enable support for generics.

It's at Project -> Properties -> Java Compiler -> Compiler Compliance Level

That does the trick, but you need Eclipse version >= 3.1 to get levels > 1.4. For Eclipse 3.5 the default level is set to 1.5. (And that actually is what you mean with 5.0, I guess.)

Oops; I see you said Eclipse 3.0; did not realize that this option is new to 3.1.

Your project is probably set to Java 1.4 target.

Sounds like you've installed 1.5 on your box, but not in Eclipse. To fix that, go to Window->Preference->Installed JREs, and add your installed JRE.
