Java程序设计语言
java 是一种可以撰写跨平台应用软件的面向对象的程序设计语言，是由Sun Microsystems公司于1995年5月推出的Java程序设计语言和Java平台（即JavaEE(j2ee), JavaME(j2me), JavaSE(j2se)）的总称。
用线程Thread执行一些方法后，需要判断执行是否成功。
public void run() {}
run( ) 方法返回值是空, 怎么办?
解决方法：
代码：
package com.example.thread;
import java.io.IOException;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;
import java.util.concurrent.Callable;
import android.util.Log;
import com.example.StreamTool.StreamTool;
public class MyThread1 implements Callable<String> {
private static final String tag = "xxxyyy";
private String phone;
private String name;
public MyThread1(String name, String phone) {
this.name = name;
this.phone = phone;
}
// public MyThread1(String name, String phone) {
// super(name);
// this.phone = phone;
// }
// public void run() {
// Log.i(tag, Thread.currentThread().getName() + "......start");
// String newpath = "http://www.dianping.com/ajax/json/account/reg/mobile/send?m=" + phone + "&flow=t&callback=DP._JSONPRequest._5";
// StringBuilder strBui = new StringBuilder(newpath);
//
// try {
// URL url = new URL(strBui.toString());
// HttpURLConnection con = (HttpURLConnection) url.openConnection();
// con.addRequestProperty("Content-Type", "text/html; charset=UTF-8");
// con.addRequestProperty(

处理返回值
ExecutorService exec = Executors.newCachedThreadPool();
ArrayList<Future<String>> results = new ArrayList<Future<String>>();
for(int i = 0; i < num; i++)
results.add(exec.submit(selectThread(telnumber)));
for (Future<String> fs:results)
try {
if (fs.get().equals("200"))
success++;
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ExecutionException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return success;以上就是本文的全部内容，希望对大家的学习有所帮助。
