}).start();|code-block|syntax|javascript|2480581|更好的做法是:不要像那样产生你自己的随机线程。使用有组织的并发策略，例如ExecutorService提供的策略。通过Executors类，您可以轻松地创建几个涵盖常见用途的类。|2480582|更好的是:查看SwingWorker和它的API+docs。|2480583|entityMap|0|LINK|mutability|MUTABLE|url|http://download.oracle.com/javase/6/docs/api/java/util/concurrent/ExecutorService.html|1|http://download.oracle.com/javase/6/docs/api/java/util/concurrent/Executors.html|2|http://java.sun.com/developer/technicalArticles/javase/swingworker/|3|http://download.oracle.com/javase/6/docs/api/javax/swing/SwingWorker.html^0|9|V|15|Z|0|0|3|Z|F|1L|8|2D|F|0|0|10|F|1N|9|10|F|0|1N|9|1|0|7|B|2|L|8|3|0^^$0|@$1|2|3|4|5|6|7|15|8|@$9|16|A|17|B|C]|$9|18|A|19|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|1A|8|@$9|1B|A|1C|B|H]|$9|1D|A|1E|B|C]|$9|1F|A|1G|B|C]|$9|1H|A|1I|B|C]]|D|@]|E|$]]|$1|I|3|J|5|K|7|1J|8|@]|D|@]|E|$L|M]]|$1|N|3|O|5|6|7|1K|8|@$9|1L|A|1M|B|C]|$9|1N|A|1O|B|C]]|D|@$9|1P|A|1Q|1|1R]|$9|1S|A|1T|1|1U]]|E|$]]|$1|P|3|Q|5|6|7|1V|8|@]|D|@$9|1W|A|1X|1|1Y]|$9|1Z|A|20|1|21]]|E|$]]|$1|R|3|-4|5|6|7|22|8|@]|D|@]|E|$]]]|S|$T|$5|U|V|W|E|$X|Y]]|Z|$5|U|V|W|E|$X|10]]|11|$5|U|V|W|E|$X|12]]|13|$5|U|V|W|E|$X|14]]]]

From that, it looks like something in <code>Calendar.reminder.addReminder()</code> or <code>Calendar.reminder.Reminderchecker()</code> is taking some time and locking up the UI since that's what's happening in the EDT.

Edit: Oh, I see. You're not doing what you think you're doing. You're executing <code>Reminderchecker</code> in the current thread. The <code>Runnable</code> returned by that method is what's getting executed in the new thread. To run <code>Reminderchecker</code> in a thread, do something like:

<pre><code>new Thread(new Runnable() {
 public void run() {
 Calendar.reminder.Reminderchecker(...);
 }
}).start();
</code></pre>

Better: Don't spawn your own random threads like that. Use an organized concurrency strategy such as provided by an <a href="http://download.oracle.com/javase/6/docs/api/java/util/concurrent/ExecutorService.html" rel="nofollow"><code>ExecutorService</code></a>. The <a href="http://download.oracle.com/javase/6/docs/api/java/util/concurrent/Executors.html" rel="nofollow"><code>Executors</code></a> class lets you easily create several that cover common uses.

Still better: Check out the <a href="http://java.sun.com/developer/technicalArticles/javase/swingworker/" rel="nofollow">SwingWorker</a> and it <a href="http://download.oracle.com/javase/6/docs/api/javax/swing/SwingWorker.html" rel="nofollow">API docs</a>.

blocks|key|2480618|text|您需要确保所有这些都发生在新线程中：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2480619|Calendar.reminder.Reminderchecker(Calendar.reminder.addReminder(date,+str+))|code-block|syntax|javascript|2480620|此刻|2480621|Calendar.reminder.addReminder(date,+str+)|2480622|和|2480623|Calendar.reminder.Reminderchecker()|2480624|在构造和启动新的Thread之前，在事件调度线程上调用。|offset|length|style|CODE|2480625|纠正此错误的最简单方法是创建一个新的Runnable对象，该对象执行所有这些步骤，然后将其传递给新线程。我猜从Reminderchecker()返回的对象本身就是一个Runnable，在这种情况下，你需要类似这样的东西：|2480626|Runnable+task+=+new+Runnable()+{

You need to make sure that all this happens in the new thread:

<pre><code>Calendar.reminder.Reminderchecker(Calendar.reminder.addReminder(date, str ))
</code></pre>

At the moment 

<pre><code>Calendar.reminder.addReminder(date, str )
</code></pre>

and

<pre><code>Calendar.reminder.Reminderchecker()
</code></pre>

are called on the Event Dispatching Thread before the new <code>Thread</code> is constructed and started.

The simplest way to correct this is to create a new <code>Runnable</code> object that carries out all of these steps, and then pass that to the new thread. I guess the returned object from Reminderchecker() is itself a <code>Runnable</code>, in which case you need something like this:

<pre><code>Runnable task = new Runnable() {
 public void run() {
 Runnable r = Calendar.reminder.Reminderchecker(Calendar.reminder.addReminder(date, str ));
 r.run();
 };
new Thread(task).start();
</code></pre>

blocks|key|4096361|text|假设您的Calendar类实现了Runnable或扩展了Thread，您不应该在启动新线程之前调用Calendar.reminder.Reminderchecker(Calendar.reminder.addReminder(date,+str+))，因为这会调用新线程的run()方法。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4096362|取而代之的是这样做：|4096363|public+class+Calendar+implements+Runnable+{

Assuming that your <code>Calendar</code> class implements <code>Runnable</code> or extends <code>Thread</code> you should not call <code>Calendar.reminder.Reminderchecker(Calendar.reminder.addReminder(date, str ))</code> before starting the new Thread as this calls the <code>run()</code> method of the new thread.

Instead do something like that:

<pre><code>public class Calendar implements Runnable {
 public void run() {
 this.reminder.Reminderchecker(Calendar.reminder.addReminder(date, str ));
 } 
}
</code></pre>

I'm trying to make so that when I press a button the program starts a method in a new thread.
The problem is that when I press the button the program freezes until the method is done running like i didn't use a thread at all. Does anyone know how to solve this problem? 

Thanks Morgan.

<pre><code>public Listeners()
{
 Calendar.ButtonAddReminder.addActionListener(new ButtonAddListener());
}

private class ButtonAddListener implements ActionListener
{
 public void actionPerformed(ActionEvent e) {
 new Thread(Calendar.reminder.Reminderchecker(Calendar.reminder.addReminder(date, str))) .start();
 }
}
</code></pre>

我正在尝试这样做，当我按下一个按钮时，程序在一个新线程中启动一个方法。问题是，当我按下按钮时，程序就会冻结，直到方法运行完毕，就像我根本没有使用线程一样。有人知道如何解决这个问题吗？谢谢摩根。public Listeners(){  Calendar.ButtonAddReminder.addActionListene...
