Special characters not accepted?

Hi, i got a problem with the character "$" in a command.

Code:

if(args[0].equals("$")){
// do something
}

for some reason, its not working. is there a special sequance for it? ( like in html for "é" its "é")

also, is there a "universal money thing" to detect if its any money "logo" or i should just do

Code:

if(args[0].equals("$") || args[0].equals("€")){ //and so on
// do something
}

Thanks

 

Putting "$" makes it a string or like a message so that doesn't have to with java so there is no Special thing you have to do like HTML as far as I know.

Also i think the best way is to do what you are doing in the second code. using the or (||) it might be longer but it will work.

 

Try echoing out args[0] just to verify that it's the correct string. To answer your second question, you would need to create a List (probably of chars) that contained every character you consider a "money logo," then check if args[0] is contained by that List.

 

so there is no way I can detect if the "args[]" is a "$"?
so if I do

Code:

Public String DollarSign = "$";

its like doing

Code:

Public String DollarSign = new String;
// which i know its not acceptable :P

?

there is surely a way to use "$" in java.. i cant believe that java cant be used with curencies

Edit:

gonna try that

The string return: $ .. as it should
But somehow it does not pass for ".equals ("$")"..

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

If you are sure that the String returned is '$', attempt a .trim() call before .equals(): there may be (in an unlikely case) some trailing or leading whitespace.

 

The actual command is:

Code:

if(args[0].equalsIgnoreCase("money") || args[0].equals("$")){
// do something
}

It work good with "money" but dont work with "$". the command return to sender where is the error and which String or Integer couldnt pass... and the word that dont pass is "$" in args[0] ..
I also added:

Code:

sender.sendMessage(ChatColor.GOLD + " " + args[0] + " " + args[1] + " " + args[2] + " " + args[3] + " " + args[4]);

in case of error, but it return a correct sequence... :S i'm troubled XD

Why .equals ("$") wouldnt accept a String which contain only $

 

Why would a command argument have leading or trailing whitespace? Aren't the args generated from a string split by space characters?

 

"in an unlikely case"

Yes, that is the expected result. However, we do not know what fork of CraftBukkit he may be using, and I know of at least one fork (which shall remain nameless) which did, at one point, have such an issue. Additionally, as `"$".equals("$")` returns true, as expected, this leads one to the conclusion that args[0] is not just "$".

 

Try

Code:java

 
if(args[0].equalsIgnoreCase("$"){
      //Do code
}
