Is there any function that can count with char value?

Question

Write a program to accept a sentence and perform the following tasks:

1. Count number of vowels and consonants present in each word

2. Generate the output of the frequency in form of a bar graph, where V denotes vowels and C denotes consonants as shown below:

Example:

INPUT:-

HOW ARE YOU?

OUTPUT:-

WORD COUNT:

HOW
V

CC

ARE
VV

C

YOU
VV

C

The thing I am asking is that how can I print V and C, the number of times the vowels and consonants is occurring.. because I can perform this with digits(like if 2 vowel are there so print 2) but I can't figure that out with char value(here, V and C)

I tried this with for loop with if statement.. but that ain't working

Please help me with this... exams are round the corner

Answer 1

Here is an example.

Maintain a String for both vowels, and consonants; I'm using a and b.
Divide the text, s, with the String#split method, and traverse each value.
From here, increment x by 1 for vowels, and y by 1 for consonants.
After the loop, print out an occurrence of either "V", or "C", for each x and y, with the String#repeat method.

String s = "HOW ARE YOU?",
       a = "aeiou", b = "bcdfghjklmnpqrstvwxyz";
int i, n, x, y;
char c;
for (String w : s.split(" +")) {
    System.out.println(w);
    x = y = 0;
    for (i = 0, n = w.length(); i < n; i++) {
        c = Character.toLowerCase(w.charAt(i));
        if (a.indexOf(c) != -1) x++;
        else if (b.indexOf(c) != -1) y++;
    }
    System.out.println("V".repeat(x));
    System.out.println("C".repeat(y));
    System.out.println();
}

Alternately, utilize the Scanner class to traverse each word.

Scanner s = new Scanner("HOW ARE YOU?");
String w, a = "aeiou", b = "bcdfghjklmnpqrstvwxyz";
int i, n, x, y;
char c;
while (s.hasNext()) {
    System.out.println(w = s.next());
    x = y = 0;
    for (i = 0, n = w.length(); i < n; i++) {
        c = Character.toLowerCase(w.charAt(i));
        if (a.indexOf(c) != -1) x++;
        else if (b.indexOf(c) != -1) y++;
    }
    System.out.println("V".repeat(x));
    System.out.println("C".repeat(y));
    System.out.println();
}

Output

HOW
V
CC

ARE
VV
C

YOU?
VV
C
