Help with UDF

Dear All,

I am have the following requirement, which I am trying to put in the UDF and facing some challenges. Kindly help.

In the UDF, I have a constant, say CONST = "A".

There is a variable, say VAR. I have to count the number of occurrences for "A" in VAR.

I am using the below code, which is throwing error (it's just a piece from rest of the code):-

char CONST = 'A';
int count = 0;
int VAR_Length = VAR.length();

	for (int i = 0; i < VAR_Length; i++)
					if (CONST.equals(VAR<i>))

I am using "Single Values" rather than "Queue" in the UDF. I intend to return a flag value of "x" from my UDF, so I am not sure how I can use "Queues" in here.

Please help. Thanks for your help and efforts.

    VAR is single variable from the source or it's an Array?

    For example let say VAR = "CAN YOU FIND A IN THIS SENTENCE" ; - Do you want to find how many A's in that VAR?

      Hi Raj,

      Thanks for your reply.

      Actually, I got another way out for the same ...

      String s = "Count, the number,, of commas.";

      int numberOfCommas = s.replaceAll("[^,]","").length();

      I will be using the above code. Anyways, I appreciate your kind help and time. Will still be rewarding you the full points.
