Java-based application is very popular nowadays, it's because Java-based applications can run on any operating system e.g. Windows, Linux, and Mac with JRE (Java Runtime Environment) installed. Recently, I wrote some Java-based applications in Ubuntu Buzz! Most of those applications work well with OpenJDK/JRE. But, if you want to use Oracle Java instead of the "open" solution, you can do it easily. For your information, Oracle Java is no longer available on Ubuntu repositories because some changes in Java license. Fortunately, there is a script which can automatically download and install the latest Oracle Java on Ubuntu.
