PUT : Update a known resource. ex: update client details. Possible Return Codes : 200(OK) DELETE : Used to delete a resource. JAX-RS JAX-RS is the JEE Specification for Restful web services implemented by all JEE compliant web servers (and application servers). Important Annotations ...
Jansi - ANSI escape codes to format console output. Jexer - Advanced console (and Swing) text user interface (TUI) library, with mouse-draggable windows, built-in terminal window manager, and sixel image support. Looks like Turbo Vision. Text-IO - Aids the creation of full console-based ap...
Java provides a lot of exception classes for us to use, but sometimes we may need to create our own custom exception classes. For example, to notify the caller about a specific type of exception with the appropriate message. We can have custom fields for tracking, such as error codes. For...
Cipher: initialized with keys, these are used for encrypting/decrypting data. There are various types of algorithms: symmetric bulk encryption (e.g. AES), asymmetric encryption (e.g. RSA), and password-based encryption (e.g. PBE). Message Authentication Codes (MAC): like MessageDigests, thes...
Being compiled into machine-readable byte-codes protects Java. Now, as we can see, other than a clever marketing scheme, there are few real similarities between Java and JavaScript. I.B. Client-side/Server-side Javascript Both client-side and server-side JavaScript share the same common core ...

There are various types of algorithms: symmetric bulk encryption (for example, AES), asymmetric encryption (for example. RSA), and password-based encryption (for example, PBE). Mac: Like MessageDigests, Message Authentication Codes (MACs) also generate hash values, but are first initialized ...
Although we are all called coders and we are all writing codes, because of the different requirements of the scenes, all kinds of coders also do different things. Some people unify the specifications, some develop components, some write businesses, and some others do verification, but the more...
Including data directly into the code can detrimentally affect the code’s performance. Termed hardcoding, this practice becomes infeasible when writing big codes. It leads to bugs and makes the code prone to errors. Let’s say you want to determine the duration spent by an employee in a co...
