Eclipse自动补全功能可运行，但不适用于线程

Question

If I type "new Runnable" and hit CTRL+SPACE, Eclipse allows me to create an anonymous inner class. However when I do the same with "Thread", it does not.

It is a bit annoying that every time I need an anonymous thread, I have to create a new Runnable and then change the "Runnable" to "Thread".

Is there a way to let Eclipse automatically create a thread as well?

Answer 1

I think Eclipse is doing this because Thread is a concrete class while Runnable is instead of an interface. Eclipse may not by default allow you to create an anonymous class which extends a concreate one.

The more accepted way to create a Thread is to use a Runnable anyway which does not restrict you to the Thread base class:

 Thread thread = new Thread(new Runnable() {
     public void run() {
        ...
     }
 });
 thread.start();
 ...

As a workaround you could create a new template for the thread creation.

Eclise (at least in 3.7) alreay has one for Runnable. You can try it if you type runnable and then Ctrl+Space until the template proposals are shown.

To create a new template for Thread :

• Open the template view Window > Show View > Templates
• Select runnable
• Copy/Paste from the context menu
• Edit the new Template by replacing Runnable with Thread

Answer 3

It does come. I am not sure how you're pressing Ctrl + Space .

Answer 4

Click "New" on this panel and create a new template. Ctrl-space will then work as you expect.

Answer 5

Yes. Avoid anonymous inner classes. You need thread? It does something important? Create normal class that extends thread and implements run() .

Moreover. Avoid creating thread instances whenever you want. User thread pools, executors etc instead.
