Java代码具体的实现，要包含测试结果

Question

Q 是一个队列，S 是一个栈。使用 Q 和 S，
实现队列 Q 中元素的逆置

Answer 1

import java.util.LinkedList;
public class MyStack {
LinkedList linkList = new LinkedList<Object>();
public void push(Object object) {
linkList.addFirst(object);
}
public boolean isEmpty() {
return linkList.isEmpty();
}
public Object pop() {
if (!linkList.isEmpty())
return linkList.removeFirst();
return "栈内无元素";
}
}
public class MyQueue {
LinkedList linkedList = new LinkedList();
public void put(Object o){
linkedList.addLast(o);
}
public Object get(){
if(!linkedList.isEmpty())
return linkedList.removeFirst();
return "";
}
public boolean isEmpty(){
return linkedList.isEmpty();
}
}

public class test{
public static void main(String[] args) {
MyStack ms = new MyStack();
MyQueue mq = new MyQueue();
mq.put(1);
mq.put(2);
mq.put(3);
while(!mq.isEmpty()){
ms.push(mq.get());
}
while(!ms.isEmpty()){
mq.put(ms.pop());
}
while(!mq.isEmpty()){
System.out.print(mq.get());
}
}
}
