Can a method take itself as parameter?
Can a method take itself as parameter? Recursive method maybe. And whats the new feature in 1.7 release. Someone told me it was something with calling multiple methods, or maybe taking other methods as parameters. Any info on thisone?

I don't know about passing a method as a parameter to a method itself. Maybe you are talking about recursive method. Can you specifically say what exactly you want to do.

A method doesn't have a type, so I don't see how it could be passed as a parameter to another method. How would you define the called method?
public void calledMethod(PassedMethod pm) {...
Then what would its parameters be if you call it?
pm(<someargs???>);
Its always possible for new syntax to be added to java. This could be defined in future versions of java.

Maybe he means:
String length = getStringLength(textField.getText());
where getStringLength is a non-existing method...

I guess it is the closures that are proposed to be added in the new versions. My teacher said something about adding very powerful stuff in the new version, but it was something to do with the methods passing as arguments in other methods, I'm not really sure. Or maybe multiple inheritance. Its all mashup now in my head with this Java thing. Tnx for the replies

I don't think new version has this kind of feature at all. I search on the Suns' official web site, but didn't found such thing.

I have heard of closures as a possible addition to the next version.
As for method parameters, these can be implemented in a sideways fashion using interfaces. We do this with Runnables all the time.

If so, it's interesting actually. I'm waiting to test it.

Nice link. I need to get my routine with some more basic stuff until i get there. Imo you need to decide when it's time to stop learning, i think many would disagree on that. But with all these new features, aspect programming etc its just another way to get things done, with less code maybe.

Don't rush. Closures are not part of Java yet, so there's nothing to "get to" just yet!

I don't disagree at all. I think you should stop learning when you're dead. I'm in no rush. |
