Java Program to Count the Total Number of Vowels and Consonants in a String
Given a String count the total number of vowels and consonants in this given string. Assuming String may contain only special characters, or white spaces, or a combination of all. The idea is to iterate the string and checks if that character is present in the reference string or not. If a character is present in the reference increment number of vowels by 1, otherwise, increment the number of consonants by 1.

Input : String = "GeeksforGeeks" Output: Number of Vowels = 5 Number of Consonants = 8 Input : String = "Alice" Output: Number of Vowels = 3 Number of Consonants = 2
- Create two variables vow and cons and initialize them with 0.
- Start string traversing.
- If i’th character is vowel then increment in vow variable by 1.
- Else if the character is consonant then increment in cons variable by 1.
Number of Vowels = 5 Number of Consonants = 8
Time Complexity: O(n²) here, n is the length of the string.
