At the time, Java was becoming a major player in the programming world, and Apple also provided a Java bridging solution that was developed for the WebObjects platform. This was a more classical bridging solution, with direct conversions between Java and OpenStep/CF types being completed in code, where required.
The bridge pattern is often confused with the adapter pattern, and is often implemented using the object adapter pattern; e.g., in the Java code below. Variant: The implementation can be decoupled even more by deferring the presence of the implementation to the point where the abstraction is utilized.

The frontend/backend distinction can separate the parser section that deals with source code and the backend that generates code and optimizes. Some designs, such as GCC , offer choices between multiple frontends (parsing different source languages ) or backends (generating code for different target processors ).
Bytecode is a portable low-level code similar to machine code, though it is generally executed on a virtual machine instead of a physical machine. [4] To improve their efficiencies, many programming languages such as Java, [4] Python, [5] and C# [6] are compiled to bytecode before being interpreted.
To use such libraries from another language, usually of higher-level, such as Java, Common Lisp, Scheme, Python, or Lua, a binding to the library must be created in that language, possibly requiring recompiling the language's code, depending on the amount of modification needed. [2]
The Java Media Framework (JMF) is a Java library that enables audio, video and other time-based media to be added to Java applications and applets. Java Topology suite Java Topology Suite (JTS) is an open-source Java software library that provides an object model for Euclidean planar linear geometry together with a set of fundamental geometric ...
Embedding scripting support with Java (Beanshell [11]). This is an important benefit as you can use a unified programming language for both user interface and backend programming. Optional support for other serverside Java scripting in other languages such as JavaScript (Rhino [12]), Ruby (JRuby [13]), Python (Jython [14]) and Groovy. [15]
