Java applet detects the concurrency of the web---httpclient and util packages concurrent

1. Download the Org.apache.commons.httpclient.jar file.

2. Use HttpClient to access the Web site (URL).

3. Use multithreading to test the number of concurrency. The Java.util.concurrent package implements concurrency.

The code is as follows:

1 Importjava.io.IOException;2 ImportJava.util.concurrent.ExecutorService;3 Importjava.util.concurrent.Executors;4 ImportJava.util.concurrent.TimeUnit;5 6 Importorg.apache.commons.httpclient.HttpClient;7 Importorg.apache.commons.httpclient.HttpException;8 ImportOrg.apache.commons.httpclient.HttpMethod;9 ImportOrg.apache.commons.httpclient.methods.GetMethod;Ten  One  A  -  -  Public classCeshi { the  -     /** -      * @paramargs -      * @throwsIOException +      * @throwsHttpException -      * @throwsinterruptedexception +      */ A      Public Static voidMain (string[] args)throwsHttpException, IOException, interruptedexception { atExecutorservice service=Executors.newfixedthreadpool (integer.max_value); -         inti = 0; -          for(i= 0; i < 4000; i++) { -System.out.println ("number" + (i+1) + "starts"); -Service.execute (NewRunnable () { - @Override in                  Public voidrun () { -                     Try { to Ceshi (); +}Catch(HttpException e) { -System.out.println ("HttpException"); the e.printstacktrace (); *}Catch(IOException e) { $System.out.println ("IOException");Panax Notoginseng e.printstacktrace (); -                     } the                 } +             }); ASystem.out.println ("number" + (i+1) + "ends"); the         } +           - Service.shutdown (); $          $           -Service.awaittermination (300, timeunit.seconds); -          theSystem.out.println ("OK"); - Wuyi     } the      -      Wu     Private Static voidCeshi ()throwsHttpException, ioexception{ -HttpClient client =NewHttpClient (); About  $Client.gethostconfiguration ().
