这是我的班级,我想对我的堆栈进行排序,但它会抛出异常请帮助我谢谢!

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());
        }
    }
}

堆栈跟踪:

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));`
