Some developers may prefer to use core Java. There are many ways for counting the number of occurrences of a char in a String. Let’s start with a simple/naive approach: StringsomeString="elephant";charsomeChar='e';intcount=0;for(inti=0; i < someString.length(); i++) {if(someStr...

Here is one way you could do it in Java: public static int countChar(String str, char c) { int count = 0; for (int i = 0; i < str.length(); i++) { if (str.charAt(i) == c) { count++; } } return count; } You can use this method like this: String str =...

Below is the function, using which you can find out the number of occurrences of a certain character in a string in Delphi. For instance, assume that you have the following string and would like to count the number of commas in it: Str := 'A,B,C'; Then y
