Android配合WebService访问远程数据库 中文WORD版
下载
采用HttpClient向服务器端action请求数据，当然调用服务器端方法获取数据并不止这一种。WebService也可以为我们提供所需数据，那么什么是webService呢？，它是一种基于SAOP协议的远程调用标准，通过webservice可以将不同操作系统平台，不同语言，不同技术整合到一起。 实现Android与服务器端数据交互，我们在PC机器java客户端中，需要一些库，比如XFire,Axis2,CXF等等来支持访问WebService，但是这些库并不适合我们资源有限的android手机客户端，
A join() is a final method of Thread class and it can be used to join the start of a thread's execution to the end of another thread's execution so that a thread will not start running until another thread has ended. If the join() method is called on a thread instance, the currently running thread will block until the thread instance has finished executing.
语法
public final void join() throws InterruptedException
示例
public class JoinTest extends Thread {
public void run() {
for(int i=1; i <= 3; i++) {
try {
Thread.sleep(1000);
} catch(Exception e) {
System.out.println(e);
}
System.out.println("TutorialsPoint "+ i);
}
}
public static void main(String args[]) {
JoinTest t1 = new JoinTest();
JoinTest t2 = new JoinTest();
JoinTest t3 = new JoinTest();
t1.start();
try {
t1.join(); // calling join() method
} catch(Exception e) {
System.out.println(e);
}
t2.start();
t3.start();
}
}输出
TutorialsPoint 1 TutorialsPoint 2 TutorialsPoint 3 TutorialsPoint 1 TutorialsPoint 1 TutorialsPoint 2 TutorialsPoint 2 TutorialsPoint 3 TutorialsPoint 3
