Write a program which takes a String input, and then prints the number of times the string "sh" appears in the String (s and h can be any case). Hint - remember there are String methods which return a copy of the String it is called on with all letter characters changed to the same case.

Sample run

Input String:
She sells seashells on the seashore
Contains "sh" 3 times.

import java.util.Scanner;

public class JavaApplication61 {

   public static void main(String[] args) {

       Scanner scan = new Scanner(System.in);

       System.out.println("Input String:");

       String text = scan.nextLine();

       text = text.toLowerCase();

       char c = ' ', prevC = ' ';

       int count = 0;

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

           c = text.charAt(i);

           if (c == 'h' && prevC == 's' && i >= 1){

               count += 1;

           }

            prevC = c;

       }

       System.out.println("Contains \"sh\" "+count+" times.");

   }

}

This works for me. Best of luck.
