Practical 5: Write a program to accept a line and check how many consonants and vowels are there in line.

Program:

import java.io.*;

class practical5

{

public static void main(String args[]) throws IOException

{

String str;

int vowels = 0, digits = 0, blanks = 0;

char ch;

BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

System.out.print("Enter a String : ");

str = br.readLine();

for(int i = 0; i < str.length(); i ++)

{

ch = str.charAt(i);

if(ch == 'a' || ch == 'A' || ch == 'e' || ch == 'E' || ch == 'i' ||

ch == 'I' || ch == 'o' || ch == 'O' || ch == 'u' || ch == 'U')

vowels ++;

else if(Character.isDigit(ch))

digits ++;

else if(Character.isWhitespace(ch))

blanks ++;

}

System.out.println("Vowels : " + vowels);

System.out.println("Digits : " + digits);

System.out.println("Blanks : " + blanks);

}

}

Output:
