We know that theStringclass offers us two methods:toUpperCase()andtoLowerCase().If a string’s (s) characters are in uppercase, then the string (s) must equal the result ofs.toUpperCase().Therefore, following this idea, let’s create two check methods, one for uppercase check and the ...
We should note a few things here. Basic idea is that we iterate through ourStringand check if its characters are of required types. By usingCharacterclass, we can easily check if a certain character is a digit, an uppercase or a lowercase character. Unfortunately, there is no similar metho...
public class Pangram { static int size = 26; static boolean isLetter(char ch) { if (!Character.isLetter(ch)) return false; return true; } static boolean check_alphabets(String input_string, int string_length) { input_string = input_string.toLowerCase(); boolean[] is_true = new boole...

In the above code, we have created a class String, one char type array data member str[30] to store the string, and public member functions getString() and isUppercase() to store the string and to check if the string is in uppercase or not....
Java Copy Explanation Scanner: We use the Scanner class to read user input. Character Input: The input character is converted to lowercase to handle both uppercase and lowercase letters. Condition Check: The program checks if the character is one of the vowels. If it’s not a vowel bu...

Example 3: Java Program to Check Alphabet using isAlphabetic() Methodclass Main { public static void main(String[] args) { // declare a variable char c = 'a'; // checks if c is an alphabet if (Character.isAlphabetic(c)) { System.out.println(c + " is an alphabet."); } else {...
The alphabets A, E, I, O and U (smallcase and uppercase) are known as Vowels and rest of the alphabets are known as consonants. Here we will write a java program that checks whether the input character is vowel or Consonant using Switch Case in Java. If
