打印兩個有序鏈表的公共部分

給定兩個有序列表的頭指針head1和head2，打印兩個鏈表的公共部分。
以下爲具體算法實現：

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