String.split() Issue

Newbie & Debugging Questions
#1

Might be Network related cause the String is from a file from a website but i guess the error is general so i post this here:

Code:

System.out.println(line);
String[] part = line.split("|");
System.out.println(part[0]);
System.out.println(part[1]);

Gives me the following output in the Console:

String contains the URL and the File where it should be placed (For a Launcher that can Update my Game) but since splitting the String in those 2 parts doesn’t work well :slight_smile: any idea why it’s doing this?

#2

I had some kind of a problem with splitting strings as well. There are some problems when you try to split URL. It contains characters that tell Java something it shouldn’t. I would just recommend you to implement your own string split method. It would probably be much faster than to try to overcome java’s string split limitations.

#3

so the problem is that the first part of it is actually an url packed in a String?

#4

URL contains certain characters that mess up java’s string splitting. From my experience at least…

#5

Now I’m totally confused, tested it with some Short other String to see if that works:

  • Hello|World
  • H
  • e

So it Splits every Letter when it should just split arround the “|”?

#6

Maybe try splitting with [icode]|[/icode] to escape it. In regex, it means or, but since there is nothing specified, it splits every letter.

#7

Okay,

\|

is an invalid Escape sequence so that won’t work, i took

|

to make sure i use a letter that doesn’t appear in the url itself, but that didn’t work so I’ll take a spacebar for it, that seems to work and i never saw an URL with a spacebar :slight_smile:

#8

I think it should work with [icode]||[/icode] Tested with regex tester.

#9 
String[] part = line.split("\\|");
#10

Using regex to split on 1 char is overkill and has serious overhead. Sadly the Java runtime library doesn’t provide this basic feature, so you’ll have to import Apache StringUtils or write your own.
