Java Coding Problems

5. Counting vowels and consonants

The following code is for English, but depending on how many languages you are covering, the number of vowels and consonants may differ and the code should be adjusted accordingly.

The first solution to this problem requires traversing the string characters and doing the following:

1. We need to check whether the current character is a vowel (this is convenient since we only have five pure vowels in English; other languages have more vowels, but the number is still small).
2. If the current character is not a vowel, then check whether it sits between 'a' and 'z' (this means that the current character is a consonant).

Notice that, initially, the given String object is transformed into lowercase. This is useful ...
