Java list using arrays or any listing method -

Friends, I have the test that I am having difficulty in doing this because I did not understand what I am just one Using the Arrange of Switch Statement I'm still new to Java so please help. Here's the question.

  Write a Function: Category IntList {Public Full Value; Public IntList Next; } Class solutions {public full solution (IntList L, int M); }   
 that, in a single link list  L  in the  N  integer and a positive integer  
 that one Single link list  L  gets an integer and a positive integer  M , values ​​stored in the  M-th  element, in the list, counting from the end While doing this, assuming that the last element in the list is index  1  is to return the function  a "1"  if it is not possible to return such a value, for example ,  L has been :  
  L = 1 - & gt; 2 - & gt; 3 - & gt; 4   
 and  M = 2  should return the function to  3 , because the value in the second element of the count from the end of the list is  3 .   
 
 
 If I am not mistaken then you need to write the program which will return the last element from a link list I - If this is a link alone list, then you need a key indicator that you have a major indicator that is called intralastic head. The following element has the code to find Kth  
  the public int solution (IntList head, int k) {IntList temp = head; Int count = 0; While (count! = K) {if (temp == null) {return -1; } Temp = temp.next; } While (temp! = Null) {head = head.next; Temp = temp.next; } Return Head. value; }   
 Not tested the entire error but it should work.
