Internally, indexOf method runs the for loop from string index 1 to its length and check every character with the given character by invokingcharAt()method. this.charAt(k)==ch where k is index from for loop. If it finds the given char then return its index. If not, returns -1. inti...
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...

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 {...
3. Using Core Java Let’s now see how we can perform the same check if we don’t want to use regular expressions. We’ll take advantage ofCharacterandStringclasses and their methods to check if all required characters are present in ourString: ...
