Explanation / Answer

import java.util.Scanner;

public class ReadStringClass {

   private Scanner scanner;

   public ReadStringClass() {
       // TODO Auto-generated constructor stub
       scanner = new Scanner(System.in);
   }

   public String readString() {

       String input;

       System.out.print("Please input a string: ");
       input = scanner.nextLine();
       return input;

   }

}

public class EstimateStringClass {

   private int numberOfUpperCase;
   private int numberOfLowerCase;

   /**
   * @param str
   */
   public void estimateString(String str) {
       numberOfLowerCase = 0;
       numberOfUpperCase = 0;
       for (int i = 0; i < str.length(); i++) {

           if (Character.isUpperCase(str.charAt(i)))
               numberOfUpperCase++;
           else if (Character.isLowerCase(str.charAt(i)))
               numberOfLowerCase++;
       }
   }

   /**
   *
   */
   public void printResults() {

       System.out.println("Number of Uppercase: " + numberOfUpperCase);
       System.out.println("Number of Lowercase: " + numberOfLowerCase);
   }

}

public class Question3 {

   public static void main(String[] args) {

       ReadStringClass readStringClass = new ReadStringClass();
       String str = readStringClass.readString();

       EstimateStringClass estimateStringClass = new EstimateStringClass();
       estimateStringClass.estimateString(str);
       estimateStringClass.printResults();

   }
}

OUTPUT:

Please input a string: Hai this Srinivas
Number of Uppercase: 2
