Count Letters,Numbers and Spacing Program in Java

In this simple article I would like to share with you my avid reader a program that I wrote in Java as my programming language I called this program Count Letters, Numbers and Spacing Program. What this program will do is to ask the user to enter a sentence and then our program will count how many capital letters, lowercase letters, digits and spacing in our given sentence. I am using ASCII decimal values for letters, numbers and spacing in my program. I hope you will my work useful in your learning in Java programming.

Sample Output of Our Program

Program Listing

import java.util.Scanner;

public class count {

    public static void main(String[] args)

      {

        char ch;

        String str;

        int uppercase=0,lowercase=0, digits=0,space=0;

        Scanner in = new Scanner(System.in);

        System.out.println("==============================================");

        System.out.println("||Count Letters,Numbers and Spacing Program ||");

        System.out.println("==============================================");

        System.out.print("\n");

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

        str = in.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++;

            }

            else if(asciivalue >=48 && asciivalue <= 57){

    digits++;

            }

            else if(asciivalue >=32){

    space++;

            }

        }

       System.out.println("\n\n");

       System.out.println("=======================");

       System.out.println("||  DISPLAY RESULT   ||");

       System.out.println("=======================");

       System.out.println("\n");
