Question

Write a program by using a class with the following specifications:

Class name: Vowel
Data members: string s; int c(to count vowels)
Member functions:
void getstr(): to accept a string
void getvowel(): to count the number of vowels
void display(): to print the number of vowels. 

Answer 1

import java.util.*;
public class Vowel
{String s;
int c;

void getstr()
{Scanner ob = new Scanner(System.in);
System.out.println("Enter a string");
s = ob.nextLine();
s = s.toLowerCase();
}

void getvowel()
{char ch;
for (int i = 0; i < s.length(); i++)
{ch = s.charAt(i);
if (ch == 'a' || ch == 'e' || ch == 'i' || ch == 'o' || ch == 'u')
c++;
}
}

void display()
{System.out.println("The number of vowels: " + c);
}

public static void main(String args[])
{Vowel vv = new Vowel();
vv.getstr();
vv.getvowel();
vv.display();
}}
