Java

Background

Java is a reflective, object-oriented programming language initially developed by James Gosling and colleagues at Sun Microsystems in 1991, as part of the Green Project. It was initially called Oak, and was intended to replace C++, although its feature set resembles more that of Objective-C.

Java should not be confused with JavaScript, a script language with which it shares only the name and a similar C-like syntax. Sun Microsystems currently maintains and updates Java regularly.

Specifications of the Java language, the JVM (Java Virtual Machine) and the Java API are community-maintained through the Sun-managed Java Community Process.

After first being made public in 1994, it achieved prominence following the announcement at 1995's SunWorld that Netscape would be including support for it in their next version of the Navigator browser.

Language characteristics

• Object orientation
• Platform independence
• Automatic garbage collection

Roguelike Issues

Java has excellent features for roguelike development:

• Object orientation.
• Platform independence.
• Ability to run on a web page as an Applet.

however, it still has some disadvantages:

• No native console support. Developers of ASCII roguelikes must decide whether to
  • Use one of existing libraries(JCurses, Charva, etc.), or
  • Develop a new library (e.g. wrapping the Curses C library and native methods), or
  • Emulate console output in plataform independant AWT (or Swing) components.
• Longer program startup time. Java has no issues with speed once running [1], especially for RL games.

Java Roguelikes

The portability of Java has led to several roguelikes adopting this language:

• CastlevaniaRL
• Tyrant
• Dweller (using Java Micro Edition, J2ME)

And there are also some roguelike projects that are being built around Java:

• Guardian Angel
• JADE
• Plutonium roguelike
