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 ...
Another thing to notice is that this time we didn’t use[A-Z]or[a-z]for letter groups, but\p{Lu}and\p{Ll}instead. These will match any kind of letter (in our case, uppercase and lowercase respectively) from any language, not only English. 3. Using Core Java Let’s now see how...

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 usingSwitch Case in Java. If you are new to java, refer t...
In JavaScript, there is no built-in function to check if every character in a given string is in uppercase format or not. So, we have to implement our function. Here, we will create a function calledisUpperCase(), an anonymous arrow function, to tell us whether all the characters in a...
Step 4: If the character is a letter (uppercase or lowercase), calculate its index in the alphabet and mark the corresponding position in array as "TRUE". Step 5: Loop through the array. Step 6: If any position is "FALSE", set flag to 0 (indicating the string is not a pangram)....
In JavaScript, includes() method checks whether a sub-string or a character is present in the string or not. It will return output in terms of true and false. This method is case sensitive, which means that it will consider uppercase and lowercase differently....
class MainClass { public static void main(String[] args) { System.out.println("Is the Latin symbol z a lowercase letter? " + Character.isLowerCase('z')); System.out.println("Is the Latin symbol a an uppercase letter? " + Character.isUpperCase('a')); } } Related...
