Answer 1

import java.util.*;
public class SQ13
{ public static void main(String t[]){ 
String s = "", ns = "";
char ch; 
System.out.println("***Program to replace vowel with the next alphabet***");
System.out.println("Enter the String");
Scanner sn = new Scanner(System.in);
s = sn.nextLine().toLowerCase();

for (int i = 0; i < s.length(); i++)
{ch = s.charAt(i);
if (ch == 'a’ || ch == 'e' || ch == 'i' || ch == '0' || ch == 'u')
ch = (char) (ch + 1);
ns = ns + ch;
}
System.out.println(ns); 
}}
