This is now the tech support thread!

Since when?

since never pepe since never

if you ask me for tech support I'm just gonna try to get you to wipe your hard drive. :V

[ConansSideWalk]

It's ok I don't need it though I expect in the future some people will ask. xD These videos came to mind. http://www.youtube.com/watch?v=YqL95vk_5Ps http://www.youtube.com/watch?v=dlHcqSxy-ZE

hmmm try restarting the computer...or open up yo control panel dawg

[aly_angelflight]

Or better yet, make sure it's plugged in and turned on. :x

[Abs.]

Or better yet, make sure it's plugged in and turned on. :x

Not just the monitor, too.

"Have you tried turning it off and on again?" =P

saw someone write an awesome program to help you calculate how much to tip a waiter at a restaurant

Spoiler:

int main(){
return 0;
}

Spoiler:

not that I don't tip at restaurants but it was still funny to me :V

XD that is sooooo hilarious. Best program ever =P

and I'm in the same boat as you akonyl

Hmm, I've been wondering for a while - is it possible (in Java) to call a function by its name? I.e. I have somehow generated a String, which is the name of a function, and now I want to call the function using that String. Of course, I could do that by something like:

Code: Select all

// s is generated String
if (s.equals("myfucntion1")) { myfunction1(); }
   else if (s.equals("myfucntion2")) { myfunction2(); }
      else if (s.equals("myfucntion3")) { myfunction3(); }
         else if (s.equals("myfucntion4")) { myfunction4(); }
            else if (s.equals("myfucntion5")) { myfunction5(); }
            // and so on

However, this will get quite impractical with a high number of functions. I'd want something like this:

Code: Select all

public boolean callFunction (String s) {
   // calls the function with a name equivalent to the String. If it doesn't exist, does not call any function and returns false, else true.
} 

Of course, having references to functions would be even better, but I doubt something like this exists

[Akonyl]

to call a function while using its name as a string, look up Reflection. I can't tell you how the java syntax goes as I've ever only used C# reflection to call functions, so you're on your own there

As for function pointers, those certainly do exist in C# and C++, but not in Java. If you want to emulate them, you'll have to do something like is discussed on this stackoverflow page, where you make a generic 1-function interface that has an "execute" command which you define elsewhere to do whatever it is you want.

arrgg I hate your coding style Callid, hurts my eyes to read your if loops

Don't worry, I'd never write something like that
After all, this is exactly why I'm asking XD
