A class Encrypt has been defined to replace only the vowels in a word by the next corresponding vowel and forms a new word. i.e. A → E, E → I, I → O, O → U and U → A
Example: Input: COMPUTER
Output: CUMPATIR
Some of the members of the class are given below:
Class name : Encrypt
Data members/instance variables:
wrd : to store a word
len : integer to store the length of the word
newwrd : to store the encrypted word
Methods / Member functions:
Encrypt( ) : default constructor to initialize data members with legal initial values
void acceptword( ) : to accept a word in UPPER CASE
void freqvowcon( ) : finds the frequency of the vowels and consonants in the word stored in ‘wrd’ and displays them with an appropriate message
void nextVowel( ) : replaces only the vowels from the word stored in ‘wrd’ by the next corresponding vowel and assigns it to ‘newwrd’, with the remaining alphabets unchanged
void disp( ) : Displays the original word along with the encrypted word
Specify the class Encrypt giving details of the constructor( ), void acceptword( ), void freqvowcon( ), void nextVowel( ) and void disp( ). Define a main( ) function to create an object and call the functions accordingly to enable the task.

Answer
AIimport java.util.Scanner;
class Encrypt
{
String wrd, newwrd;
int len;
Encrypt()
{
wrd = "";
newwrd = "";
len = 0;
}
void acceptword()
{
Scanner sc = new Scanner(System.in);
System.out.print("Enter a word in UPPER CASE: ");
wrd = sc.nextLine();
len = wrd.length();
}
void freqvowcon()
{
int vcount = 0, ccount = 0;
for (int i = 0; i < len; i++)
{
char ch = wrd.charAt(i);
if (ch == 'A' || ch == 'E' || ch == 'I' || ch == 'O' || ch == 'U')
vcount++;
else
ccount++;
}
System.out.println("Number of vowels: " + vcount);
System.out.println("Number of consonants: " + ccount);
}
void nextVowel()
{
for (int i = 0; i < len; i++)
{
char ch = wrd.charAt(i);
switch (ch)
{
case 'A': newwrd += 'E'; break;
case 'E': newwrd += 'I'; break;
case 'I': newwrd += 'O'; break;
case 'O': newwrd += 'U'; break;
case 'U': newwrd += 'A'; break;
default: newwrd += ch;
}
}
}
void disp()
{
System.out.println("Original word : " + wrd);
System.out.println("Encrypted word : " + newwrd);
}
public static void main(String args[])
{
Encrypt obj = new Encrypt();
obj.acceptword();
obj.freqvowcon();
obj.nextVowel();
obj.disp();
}
