splitting string to array
« on: Dec 10th, 2002, 10:47pm » |
|
Is there a way to "split", or "explode" a string into an Array? or Join one array into a string?
thanks

splitStrings() does it.
Code:String sentence = "a new feature in p5 that the kids will love";
String words[] = splitStrings(sentence);
// or if you have a weird separator character
String another = "if_the_text_has_underscores";
String pieces[] = splitStrings(another, '_'); |

there's also splitInts and splitFloats, which will break up a list of (only) numbers the same way.
no join() as yet, but that oughta be added soon. a simple one for the 'pieces' above would be:
Code:String joined = "";
char withWhat = ' ';
for (int i = 0; i < pieces.length; i++) {
joined += pieces[i] + withWhat;
} |
|
a smarter (faster, more complete), but more complex version (something like what'll go into p5):
Code:// join with no separator
String join(String pieces[]) {
return join(pieces, 0);
}
// join with a separator
String join(String pieces[], char separator) {
StringBuffer buffer = new StringBuffer();
for (int i = 0; i < pieces.length; i++) {
if ((i != 0) && (separator != 0)) buffer.append(separator);
buffer.append(pieces[i]);
}
return buffer.toString();
