Question

I am trying to run the following code:

List<Integer> list = Arrays.asList(1,2,3);
ArrayList<Integer> val = new ArrayList<Integer>(list);

i know that i get the list in the first line but I ran it out of curiosity. To my disbelief, val list is empty after running of the above code, at least on my Eclipse Indigo, java 1.6 machine. Any ideas?

Answer 1

The following code:

import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;

public class Test {

    public static void main(String args[]) {
        List<Integer> list = Arrays.asList(1,2,3);
        ArrayList<Integer> val = new ArrayList<Integer>(list);
        System.out.println(val.size());
    }
}

works fine for me (it outputs 3). Your problem must lie elsewhere.
