blocks|key|63607|text|您可以简单地使用Thread.sleep()来实现此目的。但是，如果您在具有用户界面的多线程环境中工作，则需要在单独的线程中执行此操作，以避免睡眠阻塞用户界面。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|63608|try{

You can simply use <code>Thread.sleep()</code> for this purpose. But if you are working in a multithreaded environment with a user interface, you would want to perform this in the separate thread to avoid the sleep to block the user interface.

<pre><code>try{
 Thread.sleep(60000);
 // Then do something meaningful...
}catch(InterruptedException e){
 e.printStackTrace();
}
</code></pre>

blocks|key|4569891|text|不要使用Thread.sleep，否则它将冻结您的主线程，并且不会从JS模拟setTimeout。您需要创建并启动一个新的后台线程，以便在不停止主线程执行的情况下运行代码。如下所示：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4569892|new+Thread()+{
++++@Override

Do not use <code>Thread.sleep</code> or it will freeze your main thread and not simulate setTimeout from JS. You need to create and start a new background thread to run your code without stoping the execution of the main thread. Like this:

<pre><code>new Thread() {
 @Override
 public void run() {
 try {
 this.sleep(3000);
 } catch (InterruptedException e) {
 e.printStackTrace();
 }


 // your code here

There is <code>setTimeout()</code> method in <a href="https://github.com/javadev/underscore-java" rel="nofollow noreferrer">underscore-java</a> library.
Code example:
<pre><code>import com.github.underscore.Underscore;
import java.util.function.Supplier;

public class Main {

 public static void main(String[] args) {
 final Integer[] counter = new Integer[] {0};
 Supplier&lt;Void&gt; incr =
 () -&gt; {
 counter[0]++;
 return null;
 };
 Underscore.setTimeout(incr, 0);
 }
}

The function will be started in 100ms with a new thread.

I need to implement a function to run after 60 seconds of clicking a button. Please help, I used the Timer class, but I think that that is not the best way.
