Java can be easily extended since it is based on the Object model. Platform Independent − Unlike many other programming languages including C and C++, when Java is compiled, it is not compiled into platform specific machine, rather into platform independent byte code. This byte code is distributed over the web and interpreted by the Virtual Machine (JVM) on whichever platform it is being run on. Simple − Java is designed to be easy to learn. If you understand the basic concept of OOP Java, it would be easy to master. Secure − With Java's secure feature it enables to develop virus-free, tamper-free systems. Authentication techniques are based on public-key encryption. Architecture-neutral − Java compiler generates an architecture-neutral object file format, which makes the compiled code executable on many proces...

AES is implemented in software and hardware throughout the world to  encrypt   sensitive data. It is essential for government computer security, cybersecurity, and electronic data protection. AES includes three block  ciphers : AES-128, AES-192 and AES-256. AES-128 uses a 128- bit  key length to encrypt and decrypt a block of messages, while AES-192 uses a 192-b...
