python challenge challenge4 之java解

1，点击图片，然后看到下个数字，接下来再输入这个数字，如此循环
2，有400次这样的next数字，所以只有用程序了
3，因为不断跳转页面，所以这个程序运行耗时比较大

import java.io.IOException;

import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.HttpException;
import org.apache.commons.httpclient.methods.GetMethod;

public class Challenge4HttpClient {
	public static void main(String[] args) throws HttpException, IOException {
		HttpClient client = new HttpClient(); 
		String nothing = "12345";
		for(int i = 0 ; i < 400; i++){
			String url = getUrl(nothing);
			GetMethod get = new GetMethod(url);
			client.executeMethod(get);
			String pageInfo = get.getResponseBodyAsString();
			nothing = searchNothing(nothing, pageInfo);
			get.releaseConnection();
		}
	}

	private static String searchNothing(String nothing, String pageInfo) {
		if(pageInfo.indexOf("Divide by two") != -1){
			nothing = String.valueOf(Integer.valueOf(nothing)/2);	
		}else if(pageInfo.indexOf("the next nothing") != -1){
			String[] strArr = pageInfo.split(" ");
			nothing = strArr[strArr.length-1];
			System.out.println(strArr[strArr.length-1]);
		}else{
			System.out.println("result = " + pageInfo);
		}
		return nothing;
	}

	private static String getUrl(String nothing) {
		StringBuilder builder = new StringBuilder();
		builder.append("http://www.pythonchallenge.com/pc/def/linkedlist.php?nothing=");
		builder.append(nothing);
		System.out.println("builder string = " + builder.toString());
		return builder.toString();
	}
