PROGRAM 7 : ENTER A STRING AND REPLACE ALL OCCURENCES OF VOWELS WITH THE ALPHABET FOLLOWING IT , INTO THE STRING.

Example:

 

 

PROGRAM:

 

 

import java.util.Scanner;

public class replacingvowels2
{
    public static void main(String args[]){
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter a string to replace its vowels:");
        String str = sc.nextLine();
        str = str.trim(); // WILL REMOVE ALL EXTRA SPACES BEFORE AND AFTER THE STRING
        str = str.toUpperCase(); // WILL CHANGE ALL CHARACTERS TO UPPERCASE
        int a = str.length();
        char ch;
        int b;
        for(int i = 0 ; i <a ; i++){
            ch = str.charAt(i);  // EACH CHARACTER WILL BE CHECKED WHETHER IT IS A VOWEL OR NOT.
            b = (int)ch; // WILL FIND THE ASCII VALUE OF CHARACTER
            switch(ch) // A TYPE OF DECISION MAKING STATEMENT THAT CHECKS CHARACTER WITH EVERY CASE
            {
                case 'A':
                case 'E':
                case 'I':
                case 'O':
                case 'U':
                b = b+1; // WILL INCREASE THE ASCII VALUE BY 1
                str = str.replace(ch , (char)b); // WILL REPLACE ALL OCCURENCES OF THE VOWEL WITH NEXT ALPHABET IN ORDER
                break;
                default:
            }
        }
        System.out.println("CHANGED STRING:");
        System.out.println(str); // WILL OUTPUT THE CHANGED STRING
    }
}
