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 ...
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...
In this quick tutorial, we’ll illustrate how we cancheck if aStringis containing at least one of each of the following: uppercase letter, lowercase letter, digit or special character in Java. 2. Using Regular Expressions One of the ways to perform our check is by using regular expressions...
() function to check if // the string is in uppercase void isUppercase() { // initializing int type variables to // perform operations int index, check = 0; // for loop to traverse the whole string for (index = 0; str[index]; index++) { // if condition to check if the ...
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)....
Write a Java program to check whether a given string is valid hex code or not. A hexadecimal color value is a six-digit code preceded by a # sign, and is exactly 6 characters in length. Each character must be an alphabetic character from A-F (uppercase or lowercase.) or a digit fro...
Write a JavaScript program to check whether a string is lower case or not. Convert the given string to lower case, using String.prototype.toLowerCase() and compare it to the original. Sample Solution: JavaScript Code: // Define a function 'isLowerCase' that checks if the given string 'str...
1. String.contains() Method The first and most popular method used in Java for checking if a string contains another string is contains() from the String class. This method returns a boolean value based on whether the substring exists in the this string or not. The contains() method search...
# Python program to check if a string is # palindrome or not # function to check palindrome string def isPalindrome(string): rev_string = string[::-1] return string == rev_string # Main code x = "Google" if isPalindrome(x): print(x,"is a palindrome string") else: print(x,"is...
