How can I move a group of nodes in a different location in a linked list in JAVA?

Question

I'm supposed to create a method fx(int index1, int index2, int index3) where the nodes of the linked list from index1 to index2 are moved after node at index3 at the correct order. I think the problem is at the second while loop but I can't figure out how to fix it. Also I'm not sure about the part that prints out the elements

public void fx(int index1, int index2, int index3) {
    Node<T> current = head;

    int index =0;
    Node<T> node3=null;
    Node<T> node1=null;
    Node<T> node2=null;
    Node<T> beforeNode1=null;
    Node<T> afterNode3=null;
    Node<T> afterNode1=null;

    while(current != null) {

        if(index==index1-1) {

            beforeNode1=current;
        }

        if(index==index1) {

            node1 = current;
        }

        if(index==index2) {

            node2=current;
        }

        if(index==index3) {

            node3=current;
        }
        index++;
        current=current.next;
    }

    node3.next=afterNode3;
    node1.next=afterNode1;

    beforeNode1.next=node3;
    node3.next=node1;

    node1.next=afterNode1;

    while(afterNode1 != null) {                   // -->the problem

        for(index=index1; index<=index2;) {

            afterNode1=afterNode1.next;

            index++;

        }
    }

    node2.next=afterNode3;

    System.out.println();
    Node<T> temp = head;

    while(temp!= null) {

        System.out.print(temp.data);

        temp = temp.next;
    }
}
