Cain	Counting characters after a character in a string in java.? This is my code (which does not work btw): public class test { public static void main (String[] args) { Scanner scan = new Scanner (System.in); int DotPos, langd; String filtyp, text; System.out.println ("whatever: "); text = scan.nextLine(); DotPos = text.indexOf("."); langd = text.length(DotPos +1); System.out.println(langd); } } so what I want to do is seen by my " langd = text.length(DotPos +1); " code, but this does not work.. I'm thinking there must be a similar solution but I'm applying it wrong. Does anyone know? If you did not understand anything of the above this is what I'm trying to accomplish: I want to make a counter for how many characters there are after a character in a string, in this case the dot. I know I could do a loop count, but I'm wondering if there is a more simple solution than that? Thanks. 2 answer(s)
	Best Answer: // The source string String text = "abc"; // The string to look for in the source string String positionText = "."; // Get the location of the search string // (Keep in mind that a -1 will be returned if it // doesn't exists) int position = text.indexOf(positionText); // This will hold the length of the characters after // the search string. The whole length will return // if the search string doesn't exist. int length = 0; // Need to check the position. -1 means no occurrence // of the positionText value. if (position > -1) { // Remember that the position is based on a zero based // array so need to add 1 to it for length length = text.length() - position + 1; } else { // No search string so return the whole length length = text.length(); } View more answers to this question.
More Answers Baron von Steuben substring your initial string into a new string variable starting at the position of the character to count after + 1. Take the length of the new string.
