In this section, you will learn java updates.
Java Update 1.4.2
Java 1.4.2 Update 2 provides improved behavior for applets in Safari and
increased stability for desktop Java applications. Java 1.4.2 Update 2 also
includes all the improvements from Java 1.4.2 Update 1.
The system will be updated to Java 1.4.2 Update 2. If the system currently has
Java 1.4.1, it will be removed. Any previous Java 1.4.2 installation will be
Java SE 6 Update
Java SE 6 Update N (formerly known as the "Consumer JRE" project) is
an update release that introduces new features and enhancements aimed at
providing an optimized consumer end user experience. Java SE 6 Update N focuses
on the following areas:
- Enhanced JRE installation experience
- The Deployment Toolkit takes the guess work out of determining
what versions of the JRE end users have installed on their PC. It supplies
Java based web applet/application deployers with a simple interface to
accomplish Java detection and installation.
- The Kernel
online installer lets first time Java users run applets and Web
Start applications without waiting for the whole JRE download. The default
Kernel installation is expected to satisfy the requirements of most Java
applets and applications and any additional libraries that may be
required at runtime are downloaded to complete the Kernel installation.
This installation mechanism let the end user get up and running
significantly faster, while the complete JRE installation takes place in
the background. See Java
Kernel FAQ for more information.
- For current users of Java SE, the JRE update mechanism has also
been improved, using a patch-in-place mechanism that translates in a
faster and more reliable update process (the patch in place mechanism will
take effect for end users who upgrade from this update release or later to
a new update release). As an added benefit, follow-on update releases will
no longer be listed as separate items in the Windows "Add or Remove
- Improved performance and look & feel
- The Quick Starter feature will prefetch portions of the JRE
into memory, substantially decreasing the average JRE cold start-up time
(the time that it takes to launch a Java application for the first time
after a fresh reboot of a PC).
- Hardware acceleration support: Java SE 6 Update N introduces a
fully hardware accelerated graphics pipeline based on the Microsoft
Direct3D 9 API, translating into improved rendering of Swing
applications which rely on translucency, gradients, arbitrary
transformations, and other more advanced 2D operations.
- A new cross-platform Swing look & feel, code name Nimbus,
provides a nice update over 'Metal' and 'Ocean'.
