Count Capital and Small Letters in Java

While learning Java programming I came up with a problem how to count the number of occurrence of capital and small letters in a given sentence or a phrase. In this sample program I use Eclipse IDE for Java that I found very easy to use. Our program will first ask the user to enter a sentence and then our program will count how many time the capital  and small letters occurs in a given sentence.

If you have some questions feel free to send me an email at jakerpomperada@gmail.com and jakerpomperada@yahoo.com.

Thank you and God Bless.

Program Listing

package Capital;

import java.util.Scanner;

public class capital {

public static void main(String[] args)

   {

       char ch;

       int uppercase=0,lowercase=0;

       Scanner scan = new Scanner(System.in);

       System.out.println("\n");

       System.out.print("Count Capital and Small Letters");

       System.out.println("\n");

     System.out.print("Please Enter a Sentence :=> ");

       String str = scan.nextLine();

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

       {

           ch = str.charAt(i);

           int asciivalue = (int)ch;

           if(asciivalue >=65 && asciivalue <=90){

               uppercase++;

           }

           else if(asciivalue >=97 && asciivalue <=122){

               lowercase++;

           }

       }

       System.out.print("======= DISPLAY RESULT ========");

       System.out.print("\n\n");

       System.out.println("Number of Lowercase letter(s) :=> " + lowercase + ".");

       System.out.println("Number of Uppercase letter(s) :=> " + uppercase + ".");

       System.out.print("\n\n");

       System.out.print("\t Thank You For Using This Program");

   }
