打印两个升序链表中共同的数据

代码：

package Algorithms;

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) {

            }
        }
        System.out.println();
    }

        System.out.print("Linked List: ");
        while (node != null) {
            System.out.print(node.value + " ");
            node = node.next;
        }
        System.out.println();
    }

    public static void main(String[] args) {

        Node node2 = new Node(1);

        printLinkedList(node2);
        printCommonPart(node1, node2);

    }
