I am new to java Thread concept.i want to read two xml files concurrently by hitting both URLs(the xml files in the URL) and store it

in two different objects.After completion of the URL reading i need to hit another URL to reset the site.Can any one give me the sample

code.....


Thanks in advance,

Hi Vinoth, welcome to CodeRanch.

You can use an ExecutorService to handle any amount of tasks that you want, and then wait until they are done before you continue. It would look roughly like this:

class MyTask implements Callable<Void> {
  
  private final URL url;
  
  MyTask(URL url) {
    this.url = url;
  }
  
  public Void call() {
    // do something with url
    return null;
  }
}

Collection<MyTask> tasks = new ArrayList<MyTask>();
for (URL url: urls) {
  tasks.add(new MyTask(url));
}

ExecutorService executor = Executors.newCachedThreadPool();
try {
  executor.invokeAll(tasks);
} catch (InterruptedException ex) {
  ex.printStackTrace();
}
executor.shutdown();

// continue program
