LinkedBlockQueue can't pass Watchable [closed]

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help cla开发者_Go百科rifying this question so that it can be reopened, visit the help center. Closed 11 years ago.

I want to ask you something i'm doing like that ..

LinkedBlockingQueue<Whatch_Directory> queue 
    = new LinkedBlockingQueue<classes.Watchable.Whatch_Directory>(); 
queue.put(classes.Watchable.Whatch_Directory.create_watchable("dir"));

but everything down from the classes.Watchable etc this is the function with the watchable class everything down him isn't showing, still only the watchable is running.

If I understand what you're asking, you're creating a Whatch_Directory class somewhere else, trying to make a LinkedBlockingQueue of such things and using a factory method create_watchable() to create one.

If so, it appears that a Whatch_Directory is extending the Watchable interface (based on your other questions). It seems that your code should become something more like:

class Whatch_Directory implements Watchable {
    public static Watchable create_watchable(String s) {
        // Your definition goes here
    }
}

LinkedBlockingQueue<Whatch_Directory> queue = 
    new LinkedBlockingQueue<Whatch_Directory>();
queue.put(Whatch_Directory.create_watchable("dir");

Some more explanation of your intent would be helpful but here are some things that I suggest you check based on my understanding:

1. Make sure that create_watchable() returns the correct type. It needs to be returning something of type Whatch_Directory based on your code.

2. Make sure that create_watchable() isn't returning null for some reason.

3. Make sure that create_watchable() isn't throwing an exception.
