java - Why are modifiers allowed for a package when they don't seem to do anything? -

-

I can declare the following package with modifier but it does not show any effect on anything: 

  Private public protected static final package com.stackoverflow.mangodrunk // ... whatever whatever {// ...}

So my question is, A modifier adds anything before the package annotation and why it will be allowed by the compiler?

Update : There seems to be a problem with the compiler bundled with Eclipse because others have mentioned that it is a compiler error using Sun's JDK is.

They are not what compiler are you using?

$ javac com / stackoverflow / mangodrunk / whatever.java com / stackoverflow / mangodrunk / whatever.java: 1: class, interface, or enum required private public protected static final package com.stackoverflow Mangodrunk; ^ 1 error

.net - C# List<T>.Find(x=>x.Rectangle.Contains(Point)) FAIL -

-
For my life, I can not understand why this code generates the following output ... I think there is a bug or something while using the list and lambda, if type one rectangle exposes the property and you use the included method of rectangle object ... and the clear statement proves true while Find list method fails .... Onway Code Public Gridskeyr Warldtokapadsb (Point location) {location = _Map.WorldToClient (location); Gridsquare gs = this.find (x => x.Rectangle.Contains (location)); GridSquare KP = G.Find (X => X. laxative canteen (location)); & Lt; GridSquare & gt; List = kp.FindAll (x => x.Rectangle.Contains (location)); U.dp (list.Count); Gridskare sub = KP.Fid (X => X. laxative canteen (location)); If (sub == faucet) {u.dp (place to look for "location"); U.dp ("The location found in the grid category" + GS toaster ()); U.dp ("Grid Square Bounds" + gs.Rectangle.ToString ()); U.dp ("location found in keypad" +...

objective c - iPhone and it's wireless area -

-
Is this a way to find other iPhones in the category of wireless areas? So I give an example. I'm staying at the airport somewhere I have an iPhone too. I and the other iPhone owners are playing the same game. Is there any way to warn me and the other player that we are close to each other? Does this work even if we are not on the same wireless network, or there is no wireless? And if there is any way to do this, can you give me some starting point? Like a link where I can learn something like this or maybe this is probably the name of this process, because I do not know how to search about this topic in Google. Thanks in advance! Can be completed with peer-to-peer discovery and connectivity you are describing Game Kit Framework Originally I thought it works only through Bluetooth, but after watching it immediately, it seems that WiFi is also supported. Hope it helps!
