Write a program whose input is a character and a string, and whose output indicates the number of times the character appears in the string.

Ex: If the input is: n Monday,
the output is: 1
Ex: If the input is: z Today is Monday,
the output is: 0
Ex: If the input is: n It's a sunny day,
the output is: 2
Case matters. n is different than N.
Ex: If the input is: n Nobody,
the output is: 0

Your program must define and call the following function that returns the number of times the input character appears in the input string.

int CountCharacters(char userChar, string userString)

The program written in Java is given in the explanation section

Explanation:

public class num9 {

//Defining the method CountCharacters()

   public static int CountCharacters(char userChar, String userString){

       int c = userString.length();

       int count=0;

       for(int i=0; i<c; i++){

           if(userString.charAt(i)==userChar){

               count++;

           }

       }

       return count;

   }

//Main method begins here

   public static void main(String[] args) {

   char n ='n';

   String word = "Monday";

//Calling the method CountCharacters()

       System.out.println(CountCharacters(n,word));

   }

}
