打印有序链表公共部分

有两个有序链表，1 -> 3 -> 5 -> 6     ,   1 -> 2 -> 5 -> 7 -> 8  ,打印公共部分

public class PrintCommonPart {

    public static class Node {
        public int value;
        public Node next;

        public Node(int data) {
            this.value = data;
        }
    }

    public static void printCommonPart(Node head1, Node head2) {
        System.out.print("Common Part: ");
        while (head1 != null && head2 != null) {
            if (head1.value < head2.value) {
                head1 = head1.next;
            } else if (head1.value > head2.value) {
                head2 = head2.next;
            } else {
                System.out.print(head1.value + " ");
                head1 = head1.next;
                head2 = head2.next;
            }
        }
        System.out.println();
    }
    
    public static void main(String[] args) {
        Node node1 = new Node(1);
        node1.next = new Node(3);
        node1.next.next = new Node(5);
        node1.next.next.next = new Node(6);

        Node node2 = new Node(1);
        node2.next = new Node(2);
        node2.next.next = new Node(5);
        node2.next.next.next = new Node(7);
        node2.next.next.next.next = new Node(8);

        printCommonPart(node1, node2);

    }
