Cocoa
Cocoa is an application environment that is
what’s called object oriented. Its used to make fully
Mac OS X native applications. A cocoa framework is meant to
have rapid development and be very productive.
Carbon
Carbon includes a set of what’s called
API (Application Program
Interfaces) that used to create OS X
applications using C+ and C++ that can take advantage of
Quartz 2D graphics, multi-processing, other OS X underlying
technologies. It provides services such as OpenGL, drawing,
Mach microkernel and BSD Unix services. Carbon apps
don’t really look any different from the users eye
from a cocoa app. It’s really how the application was
programmed. Carbon apps can do fairly similar things as
cocoa apps, it generally just takes more work to get there.
The difference is how the apps are programmed to get
something accomplished.
Java
Java is built into the OS using the Java 2
foundation. It allows java developers to easily distribute
their java apps as native OS X applications to users.
Developers can also take advantage of the Mac OS Java
specific features as well as some cocoa based API’s.
