StringUtils class

🚀 StringUtils — A collection of common string manipulation utilities.

This class provides static methods for checking string properties, modifying, formatting, parsing, and cleaning strings. It aims to simplify typical string-related tasks like trimming, tokenizing, quoting, and path manipulation.

📦 Example Usage:

StringUtils.hasText(' hello ');                      // true
StringUtils.trimAllWhitespace('  a b  ');            // 'ab'
StringUtils.countOccurrencesOf('abcabc', 'a');       // 2
StringUtils.cleanPath('/foo/../bar');                // '/bar'
StringUtils.tokenizeToStringArray('a,b;c', ',;');    // ['a', 'b', 'c']

All methods are static and null-safe where applicable.
