LinkedList,ArrayList末尾插入谁效率高?

废话不多说,原因不解释,上测试代码:
package com.letv.cloud.cdn.jtest;

import java.io.IOException;
import java.util.ArrayList;
import java.util.LinkedList;
import java.util.List;
import java.util.concurrent.TimeUnit;

import org.slf4j.LoggerFactory;

import com.google.common.base.Stopwatch;

public class JtestMain {
	
	private final static org.slf4j.Logger LOGGER = LoggerFactory.getLogger("JtestMain");
	
	private static Stopwatch stopWatch = new Stopwatch();

	public static void testList(int num){
		List<String> aList = new ArrayList<String>();
		List<String> lList = new LinkedList<String>();
		stopWatch.reset();
		stopWatch.start();
		for(int i=0; i<num; i++){
			aList.add("201411180827	cctv5_800	83	796.03	115.182.51.134	123.125.89.75	in	uuid1	5");
		}
		LOGGER.info("insert num:{} ArrayList cost:{} ms",num,stopWatch.elapsedTime(TimeUnit.MILLISECONDS));
		
		stopWatch.re
;
