PROGRAM TO PRINT THE ASCII CODES OF LETTERS

 

ASCII stands for AMERICAN STANDARD CODE FOR INFORMATION INTERCHANGE. 

It returns the integer values of the characters specified 

A to Z  The ASCII code is from 65 - 90

a to z    The ASCII code is from 97 - 122

0 to 9    The ASCII code is from 48 - 57

Space character (' ' ) The ASCII code is 32.

 The following program segment shows how to print the ASCII values of capital letters and small letters.

import java.util.*;

class ASCII

{

    public static void main (String args[])

    {

        Scanner ob = new Scanner (System.in);

        System.out.println("Press 1 for unicode of capital letters");

        System.out.println("Press 2 for unicode of small letters");

        System.out.println("enter your choice");

        int choice = ob.nextInt();

        switch(choice)

        {

            case 1 :

            char ch;

        System.out.println("LETTERS \t  UNICODE");

        for(ch = 'A' ; ch <= 'Z' ; ch++)

        {

            System.out.println(ch +"\t" + (int)ch);

        }break;

        case 2:

        char cs;

        for(cs = 'a' ; cs <= 'z'; cs++)

        {

            System.out.println(cs+ "\t"+(int)cs);

        }

        break;

        default :

         System.out.println("wrong choice entered");

    }

}

}
