Convert list to array in Java [duplicate]

Answer 1

This is works. Kind of.

public static Object[] toArray(List a) {
    Object[] arr = new Object[a.size()];
    for (int i = 0; i < a.size(); i++)
        arr[i] = a.get(i);
    return arr;
}

Then the main method.

public static void main(String[] args) {
    List list = new ArrayList() {{
        add("hello");
        add("world");
    }};
    Object[] arr = toArray(list);
    System.out.println(arr[0]);
}
