    <p>There is no unique answer to your question. It depends on what the thread does. First of all, how do you plan to stop that thread?</p> <ol> <li>If it elaborates some stuff, and this stuff is made of "tokens" such as single "tasks" to do, and the thread grabs them from a <code>BlockingQueue</code> for example, then you can stop the thread with a so-called "poison pill", like a mock task that the thread reads as: "Hey man, I have to shut down".</li> <li>If the thread does something which cannot be "divided" into "steps" then you should actually tell us how do you think it can be shut down. If it blocks on <code>read()</code>s on a socket, you can only close the socket to unblock it.</li> </ol> <p>Please note <code>interrupt()</code> is not meant to stop a <code>Thread</code> in normal circumstances, and if you <code>interrupt()</code> a thread, in most cases it'll just go on doing its stuff. In 99.9% of cases, it is just bad design to stop a thread with <code>interrupt()</code>.</p> <p><strong>Anyway, to stop it after 5 seconds, just set a <code>Timer</code> which does so. Or better <code>join</code> it with a timeout of 5 seconds, and after that, stop it. Problem is "how" to stop it. So please tell me how do you think the thread should be stopped so that I can help you in better way.</strong></p> <p>Tell me what the thread does.</p> <p>EDIT: in reply to your comment, just an example</p> <pre><code>class MyHTTPTransaction extends Thread { public MyHTTPTransaction(.....) { /* ... */ } public void run() { /* do the stuff with the connection */ } public void abortNow() { /* roughly close the connection ignoring exceptions */ } } </code></pre> <p>and then</p> <pre><code>MyHTTPTransaction thread = new MyHTTPTransaction(.....); thread.start(); thread.join(5000); /* check if the thread has completed or is still hanging. If it's hanging: */ thread.abortNow(); /* else tell the user everything went fine */ </code></pre> <p>:)</p> <p>You can also set a <code>Timer</code>, or use <code>Condition</code> on <code>Lock</code>s because I bet there can be some race condition.</p> <p>Cheers.</p>

    1. COThe thread is sending an http post, which is run once. Problem is depending on network connectivity this post can take anywhere between 2 and 10 seconds. If it takes more than 5 seconds I should just stop. So I dont know how I can stop the thread running. Perhaps I can set a timeout on the http post.

    2. COYeah, in that case you should try to set a timeout in the HTTP post. But I don't think there's a timeout if for example, the upload goes 1 byte / second. The timeout is for connection handshaking and inactivity, "slow activity" just goes on. So you can however set a `Timer`, which brutally shuts down the connection after 5 secs, causing your thread to stop as a side effect.

    3. COHow can I use Timer in this way ? do you mean using the cancel method on Timer after a period of time ?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
