Queue 的應用

import java.util.ArrayDeque;
import java.util.Deque;

public class NewClass {
    public static void main(String[] args){
    
        Deque<String> stack = new ArrayDeque<>();
        stack.push("One");
        stack.push("Two");
        stack.push("Three");
        
        int size = stack.size() -1;
        while(size >= 0){
            System.out.println(stack.pop());
        }
    }
}
