Background

Java is a high-level, platform-independent, object-oriented programming language originally developed by Sun Microsystems and released in 1995. Java is currently owned by Oracle, which purchased Sun on April 20, 2009.

Very few computers can run Java programs directly. Therefore the Java environment is normally made available by installing a suitable software component. For Windows computers, this is usually done by downloading the free Java Runtime Environment (JRE) from Oracle which allows the system to run Java programs. The easiest way to do this is from java.com.

Developers frequently need additional tools which are available in the free Java Development Kit (JDK) alternative to the JRE, which for Windows must be downloaded from Oracle and installed manually.

Note: Other vendors exist but usually have license fees. For Linux and other platforms consult the operating system documentation.

More information:

Java source code is compiled to an intermediate form (bytecode instructions for the Java Virtual Machine) that can be executed with the java command.

Is using two languages in a game engine a good idea?

I'm thinking about making a game engine, as a learning project. I know Java the best, and I figure most of the code is not going to be running that much of the time, given the 20/80 rule. Why not write most of it in a language I know? For the part…
