a JDK 1.1 friendly String.split()...

just discovered that the java.lang.String.split() method is JDK 1.4 only. here is a homemade JDK 1.1 friendly replacement for those of you who need to run in browsers. it assumes that you expect words to be separated by spaces only.
oh, just realized: only single spaces allowed! you've been warned. I guess using StringTokenizer would've been more robust, but I just hacked this up...
Code:String[] split(String s) {
int cnt=0,index;
String parsed[],tmp;
// Strip trailing spaces...
while(s.endsWith(" ")) s=s.substring(0,s.length()-1);
// Find number of words in string
for(int i=0; i<s.length(); i++)
if(s.charAt(i)==' ') cnt++;
parsed=new String[cnt+1];
tmp=s;
for(int i=0; i<cnt+1; i++) {
index=tmp.indexOf(" ");
if(index!=-1) {
parsed[i]=tmp.substring(0,index);
tmp=tmp.substring(index+1);
}
else parsed[i]=tmp;
}
return parsed;

updated version with specifiable separator:
Code:String[] split(String s,char separator) {
int cnt=0,index;
String parsed[],tmp;
// Strip trailing separators...
while(s.endsWith(separator))
s=s.substring(0,s.length()-1);
// Find number of words in string
for(int i=0; i<s.length(); i++)
if(s.charAt(i)==separator) cnt++;
parsed=new String[cnt+1];
tmp=s;
for(int i=0; i<cnt+1; i++) {
index=tmp.indexOf(separator);
if(index!=-1) {
parsed[i]=tmp.substring(0,index);
tmp=tmp.substring(index+1);
}
else parsed[i]=tmp;
}
return parsed;

this is also why splitStrings() exists in the p5 api.

you know, now that I think about it, that makes a lot of sense...
typical, I never even looked for it.

hello
I cant seem to get splitStrings() to work
this is the line
String[] dataBlock = nmea.splitStrings();
and I get this error
no method named 'splitStrings" was found in type 'java.lang.String"
what am I doing wrong?

you used incorrect syntax. the correct syntax is.
String[] dataBlock = splitStrings(nmea);

fyi.. in rev 69 this is now just called 'split()'. so the syntax would be:
String[] dataBlock = split(nmea);
