... Interfaces and their methods are implicitly abstract and adding that modifier makes no difference. Is there other rules that applies with an abstract interface? No, same rules apply. The method must be implemented by any (concrete) implementing class. If abstract is obsolete, why is it ...

...locate is used when the SVN server's location changes. switch is only used if you want to change your local working copy to another branch or another path. If using TortoiseSVN, you may follow instructions from the TortoiseSVN Manual. If using the SVN command line interface, refer to this section o...

... An interface can't have behavior or state because it is intended to specify only an interaction contract, no implementation details. 'No behavior' is enforced by not allowing method/constructor bodies or static/instance initializing blocks. 'No state' is enforced by only allowing static final fie...

... show which operating system someone is using. What it does is that, it sniffs your core operating system model, for example windows nt 5.1 as my own. It then passes windows nt 5.1/i to Windows XP as the operating system. Using: '/windows nt 5.1/i' => 'Windows XP', from an array. You could s...

...ter that it gets filtered again on the client case sensitively. Of course, if you happen to have thousands of entries that match case insensitive, but only one of them is the correct one case sensitive, then it's a lot of overhead. But I don't think that reality will present such scenarios... :) ...

... This is a well-known problem with Java type erasure: T is just a type variable, and you must indicate actual class, usually as Class argument. Without such information, best that can be done is to use bounds; and plain T is roughly same as '...

... @DavidS Thanks for the link! Yeah, I was wrong, reading my comment now I see that my rephrase was incorrect. As you said: An inner class interacts with the instance members through an implicit reference to its enclosing class, and this points out another interesting property of non-static in...

... function, class, or module in which they're assigned. Control blocks like if and while blocks don't count, so a variable assigned inside an if is still scoped to a function, class, or module.
