用LinkedList模拟栈数据结构的集合，并测试。

import java.util.LinkedList;

/**

public class MyStack {
private LinkedList link;

public MyStack() {
link = new LinkedList();
}
public void add(Object obj) {
link.add(obj);
}
public Object get() {
return link.removeFirst();
}
public boolean isEmpty() {
return link.isEmpty();
}

}

public class LinkedListDemo {


public static void main(String[] args) {
//创建对象
MyStack ms =new MyStack();

//添加元素
ms.add("hello");
ms.add("java");
ms.add("bug");


// System.out.println(ms.get());
// System.out.println(ms.get());
// System.out.println(ms.get());
while(!ms.isEmpty()) {
System.out.println(ms.get());
}
}


}
