Count Comma's from a String

fahadkalis

Hi, Do I know which command in Processing will allow me to count comma's from a string?

What have you tried? You might take a look at the Processing reference or the Java API (or JavaScript, depending on which mode you're using) for useful functions.

I have a long string like GPS= "78,54,675,24,426,52,6435,452," want to count "COMMAs" inside it.

There are lot of ways to do that, from looping over each character of the string, to a method I like, which is a bit overkill, but works well and is quite concise:

 String GPS = "78,54,675,24,426,52,6435,452,";
 String cl = GPS.replaceAll("\\d", "");
 print(cl.length());
 exit();

static final int countChar(CharSequence s, char c) {
  int n = 0, i = s.length();
  while (i-- != 0)  if (s.charAt(i) == c)  ++n; 
  return n;
}
