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: private static boolean checkString(String input) { String specialCha...

We can use theisDigit()method of theCharacterclass to check each character in a loop. It returns eithertrueorfalsevalue. publicclassSimpleTesting{publicstaticvoidmain(String[]args){String str="1123";booleanisNumeric=true;for(inti=0;i<str.length();i++){if(!Character.isDigit(str.charAt(i))...
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...
