    Node tempHeader = null;

Answer 1

In this case no return value is needed.

public void removeDuplicates(Node list) {
    while (list != null) {
        // Walk to next unequal node:
        Node current = list.next;
        while (current != null && current.data.equals(list.data)) {
            current = current.next;
        }
        // Skip the equal nodes:
        list.next = current;
        // Take the next unequal node:
        list = current;

    }
}
