Java访问字符串数组中的特定元素 [英] Java accessing specific element in array of strings

问题描述

我正在运行一个供自己使用的Web搜寻器.我下载了一个，并希望为其提供种子.我想提供约50颗种子.所以我创建了一个字符串数组.我想为爬虫每次通过我的for循环提供1个种子.我的代码是:

I am running a web crawler for my own use. I downloaded one and want to provide it with seeds. I want to provide it with around 50 seeds. So I created an array of strings. I want to provide the crawler with 1 seed each time it goes through my for loop. My code is :

String [] temp =新的String []{"http://www.random.org/"、"http://www.wikipedia.org/"，"http://www.jlworld.com/"，"http://www.frys.com/"};

String[ ] temp = new String[ ] {"http://www.random.org/","http://www.wikipedia.org/", "http://www.jlworld.com/","http://www.frys.com/"};

String [] urls = new字符串[temp.length];

String[ ] urls = new String[temp.length];

  for (int i = 0; i <=temp.length; i++)       
     {          
        urls[i] = temp[i];      
     }

搜寻器需要将一个字符串分配给url.就像这样:

The crawler needs a string assigned to urls. So like :

String [] urls = new String [1];

String[ ] urls = new String[1];

urls [0] ="http://www.google.com/";

urls[0] = "http://www.google.com/";

所以它像那样工作.虽然我的代码遇到了出站异常.我想做的是，每当它通过for循环时，就为爬虫提供1种种子.任何帮助，将不胜感激！

So it works like that. I get an outofbounds exception though for my code. What I want to do is provide the crawler with 1 of the seeds each time it goes through the for loop. Any help on this would be appreciated!

推荐答案

for (int i = 0; i <=temp.length; i++)

应该是:

for (int i = 0; i <temp.length; i++)
