regex

[philthee]

Hi again,

been struggling to get a simple regex to work.

I want to remove all instances of the period . character from my line but i can't quite figure it out.

from my code

String bandName = toks.nextToken();
String temp = bandName;
Pattern removePeriods = Pattern.compile("\\W"); // i think??
Matcher matcher = removePeriods.matcher(temp);

// as far as i can see that should find the first instance of . (period character)
// if so, how do i substitute it with nothing?

Regex under Java sucks.

Anyways, playing around with it, I think I discovered how to accomplish your goal. I'm not sure where the '\W' came from, but here's what I did to remove periods:

    String foo = ".f.o.o.b.a.r.";
    Pattern pattern = Pattern.compile("[\\.]");
    System.out.println(pattern.matcher(foo).replaceAll(""));

nice one chief!
\\W removes any non word characters i think.
anyhoos, if i want to put the new string back in to my bandName variable how do i do that?

i now have

String bandName = toks.nextToken();
String temp = bandName;
Pattern removePeriods = Pattern.compile("[\\.]");
System.out.println(removePeriods.matcher(temp).replaceAll (""));

i tried

String bandName = temp;
but netbeans does not like that statement after the other code because "bandName has already been defined in java Main"

actually if i do this then this should be ok i would presume

String bandName = toks.nextToken();

Pattern removePeriods = Pattern.compile("[\\.]");
System.out.println(removePeriods.matcher(bandName) .rep laceAll (""));

no need to put it in to a temp variable and then p8utting it back again

hmmmm, doesn't seem to work, i still just get the periods in bandNAme a few lines of code later when i ask to print.
