AJ Utilities

A Lightweight Java OOP Utils Library.

---

This is a Java toolkit that truly embraces Object-Oriented Programming (OOP). Unlike other libraries that rely heavily on static methods, this toolkit requires you to instantiate objects before invoking utility methods.

By utilizing overloaded constructors, it automatically adapts to and converts various input parameters. This approach not only handles complex scenarios with ease but also results in a cleaner API design and more concise, DRY (Don't Repeat Yourself) code.

Furthermore, this library is designed to be lightweight with minimal dependencies. The JAR file is only about 170KB in size and includes the following modules:

Class/Package Module	Detail Description	Memo
BytesHelper	Byte array utility class
CollUtils	Collection utility class
ConvertBasicValue	Attempts to convert target type, note that not all types can be converted
DateHelper	Date utility class
EncodeTools	String URL/Base64 encoder
MessageDigestHelper	MD5/SHA1/SHA256/384/512 encryption utility class
ObjectHelper	A helper for Java Object
HTTP Request	A Small HTTP Request Component
RandomTools	Random Numbers and Strings
RegExpUtils	Regular expression utility class
StrUtil	String utility class
JsonUtil	Encapsulation of Jackson Library: Conversion Methods Between JSON, Map, Bean, and List	Jackson is the only library that dependencies
XmlHelper	XML processing utility class
Cryptography	AES/RSA encryption and decryption package
IO	File, resource, stream utility package
