//TestCode.java
import java.util.LinkedList;
import java.util.Stack;
public class TestCode {
    public static void main(String[] args) {
        LinkedList<Integer> list = new LinkedList<>();
        Stack<Integer> stack = new Stack<>();

        // Populating list with numbers 1,2,3
        list.add(1);
        list.add(2);
        list.add(3);

        // converting linked to stack
        for(int i = 0;i<list.size();i++){
            stack.push(list.get(i));
        }

        // Printing content of stack
        while (!stack.isEmpty()){
            System.out.println(stack.pop());
        }
    }
}
