Use string methods to find and count vowels in a string?

Question

I have this problem for homework (I\'m being honest, not trying to hide it at least) And I\'m having problems figuring out how to do it.

Given the following declarat

Answer 1

I don't see the need to have a print statement in the loop.

String s = "Whatever you want it to be.".toLowerCase();
int vowelCount = 0;
for (int i = 0, i < s.length(); ++i) {
    switch(s.charAt(i)) {
        case 'a':
        case 'e':
        case 'i':
        case 'o':
        case 'u':
            vowelCount++;
            break;
        default:
            // do nothing
    }
}

This converts the string to lowercase, and checks all the characters in the string for vowels.
