A question about JAVA linked list

Hello, I have modified it for you. You have added a comment on the modification. If you have any questions, please ask me:
Public class BaiduTest05 {
Public static void main (String [] args ){
Createline stu = new createline (10 );
Stu. Print (12 );

Class child {

Int num;
Child next = null;

Public child (int num ){
This. num = num;

Class createline {

Int len;
Child head = null;
Child p1 = null;

**************************************** ************
* Create constructor and create a circular linked list
**************************************** ************
Public createline (int len ){
This. len = len;
For (int I = 1; I <= this. len; I ++ ){
If (I = 1 ){
Child p2 = new child (I );
Head = p2;
P1 = p2;
} Else {
Child p2 = new child (I ); = p2;
P1 = p2;
} = head; // put this sentence outside the for loop.
// P1 = head; // question point --> no use of this sentence

* Print the linked list
Public void Print (int len) {// you can see that you are a circular Linked List by adding parameters here. Otherwise, how can you see the length of the printed linked list?
Child p2 = p1 = head;
For (int I = 1; I <= len; I ++ ){
System. out. println (p2.num );
P2 =;
P1 = p2;
P1 = this. head;
