In this example, we will use the while loop to check the beginning of the string: Open Compiler public class Example2 { public static void main(String []args) { // initializing the string String str = "Tutorials
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...
This is another Java program that checks whether the string is a pangram. Here, we encapsulate the operations in functions. Open Compiler public class Pangram { static int size = 26; static boolean isLetter(char ch) { if (!Character.isLetter(ch)) return false; return true; } static boo...
