LInkedList特有方法演示

package java_test;

import java.util.LinkedList;

public class LinkedListDemo {

	public static void main(String[] args) {
		// TODO Auto-generated method stub

		LinkedList link = new LinkedList();
		link.addFirst("abc1");
		link.addFirst("abc2");
		link.addFirst("abc3");

		//演示 XXX first  XXXlast 方法
		//获取,只返回
//		System.out.println(link.getFirst());//abc3
//		System.out.println(link.getFirst());//abc3

		//remove方法删除的同时，还会返回删除的元素
//		System.out.println(link.removeFirst());//abc3
//		System.out.println(link.removeFirst());//abc2

		//取出元素
		while(!link.isEmpty())
			System.out.println(link.removeLast());

	}

}

　运行结果：

p.p1 { margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Monaco }
