Hi this is my class and I want to sort my stack but it will throw an exception please help me thanks!

public class jj {
public static void main(String[] args){
Stack<Integer> s = new ImplimentingAStackUsingAnArrayOfAGivenSizeN(5);
s.push(1);
s.push(3);
s.push(5);
s.push(2);
s.push(4);
Collections.sort((List<Integer>) (s));
 System.out.println(s);
while (!s.isEmpty()) {
    System.out.println(s.pop());


}
}
}

the stack traces:

run:
Exception in thread "main" java.lang.ClassCastException: datastructurechapter5.ImplimentingAStackUsingAnArrayOfAGivenSizeN cannot be cast to java.util.List
        at datastructurechapter5.jj.main(jj.java:24)     `Collections.sort((List<Integer>) (s));`
