java用链表实现栈

1.上次用写了链表，今天正好拿链表实现一下栈（后进先出）
2.上次写的链表的地址：https://blog.youkuaiyun.com/qq_42528170/article/details/98738186
3.这个栈实现了一个接口，先把接口代码粘出来
4.如有不正之处，欢迎指正哦！
接口如下：

package com.imp;

public interface Stack <E>{
	int getSize();
	boolean isEmpty();
	void push(E e);
	E pop();
	E peek();
}

栈实现如下：

package com.imp;

public class LinkListStack <E> implements Stack<E>{
	
	private LinkList<E> list;
	
	public LinkListStack(){
		list = new LinkList<>();
	}
	
	
	@Override
	public int getSize() {
		// TODO Auto-generated method stub
		return list.getSize();
	}

	@Override
	public boolean isEmpty() {
		// TODO Auto-generated method stub
		return list.isEmpty();
	}

	@Override
	public void push(E e) {
		// TODO Auto-generated method stub
		list.addFirst(e);
	}

	@Override
	public E pop() {
		// TODO Auto-generated method stub
		return list.delete(0);
	}

	@Override
	public E peek() {
		// TODO Auto-generated method stub
		return list.find(0);
	}
	public String  toString() {
		StringBuffer stringBuffer = new StringBuffer();
		stringBuffer.append("Stack:top");
		stringBuffer.append(list);
		return stringBuffer.toString();
	}

}
