public class LetterCount {

  

   public static void main(String[] args) {

       Scanner sc = new Scanner(System.in);

      

       System.out.print("Enter a string: ");

       String line = sc.nextLine();

      

       System.out.print("Enter a letter to search: ");

       char c = sc.next().charAt(0);

      

       sc.close();

      

       int count = 0;

      

       // looping over characters of input string

       for(int i=0; i<line.length(); i++) {

          

           // increasing the count if it matches with c

           if(c == line.charAt(i))

               count++;

       }

      

       System.out.println("The letter "+c+" appears "+count+" times in the string: ""+line+""");
