String to Uppercase Program - ICSE 2025 Computer Science

Question 5


Define a class to accept a string and convert the same to uppercase. Create and display the new string by replacing each vowel by immediate next character and every consonant by the previous character. The other characters remain the same.


Example:
Input: #IMAGINATION@2024
Output: #JLBFJMBSJPM@2024

Java 
import java.util.Scanner;
class Change{
    public static void main(String[] args){
        Scanner in = new Scanner(System.in);
        System.out.print("Enter the string: ");
        String s = in.nextLine().toUpperCase();
        String t = "";
        for(int i = 0; i < s.length(); i++){
            char ch = s.charAt(i);
            if(Character.isLetter(ch)){
                if("AEIOU".indexOf(ch) >= 0)
                    t += (char)(ch + 1);
                else
                    t += (char)(ch - 1);
            }
            else
                t += ch;
        }
        System.out.println(t);
    }
}
