What is Java?
Java is a general-purpose, concurrent, class-based, object-oriented programming language specifically designed to have as few implementation dependencies as possible. It lets application developers 'write once, run anywhere' (WORA), meaning that coders can write a single application and compile it on many platforms without rewriting it. These targeted applications include enterprise software systems, applets, browser plugins, J2ME apps, and other applications that have already driven the popularity of Java technology on the server and the embedded platform.
What is Opkg?
Opkg is the package management system used on embedded Linux systems, most notably OpenWrt. It was designed to replace the Rpm Package Manager (RPM), Debain packages, Alien packages, and the Red Hat Package Manager (RPM), but it can be used with any Linux distribution. With opkg you can easily download and install software packages from the Internet to keep your router up to date without a lot of hassle.
