The Java Development Kit (JDK(TM)) is the development environment for building applications, applets, and components that can be deployed on the Java platform. This README file covers both the JDK Production Release for Windows and the JDK Reference Implementation for Solaris. A Japanese version of this README is on the Java Software website at http://java.sun.com/products/jdk/1.2/ja/README. JDK software includes tools useful for developing and testing programs written in the Java programming language and running on the Java 1.2 platform. These tools are designed to be used from the command line. Except for appletviewer, these tools do not provide a graphical user interface. On Windows, a separate Java Runtime Environment including Java Plug-in is also installed with the JDK. On Solaris, you can obtain this separately. For more information, see Java Runtime Environment including Java Plug-in. Features Version 1.2 of the Java Development Kit offers significant improvements in functionality, performance, security and global support. See: * Summary of New Features - Features added since JDK 1.1. http://java.sun.com/products/jdk/1.2/docs/relnotes/features.html * Guide to Features - Complete list of all features. http://java.sun.com/products/jdk/1.2/docs/index.html#guide JDK Documentation The JDK Documentation contains release documentation, Java API specifications, developer guides, tool documentation, demos, and links to related documentation. It is available in a separate download bundle. If you have not already downloaded your own local copy of the JDK Docs, you can do so from the JDK 1.2 download page. System Requirements The JDK 1.2 software is available on three platforms: * Win32 Release for Windows 95, Windows 98 and Windows NT on Intel hardware. For Windows NT, only version 4.0 is supported.

At least 48 megabytes of RAM is recommended. Solaris patches may need to be installed (see installation instructions). * Solaris/Intel Release. Only Solaris versions 2.5.1, 2.6 and 7 (also known as 2.7) are supported. A 486/DX or faster processor and at least 48 megabytes of RAM are recommended. Solaris patches may need to be installed (see installation instructions). On Solaris, Sun releases both a Reference Implementation and Production Release. See: http://java.sun.com/products/jdk/faq.html#prod|ref On all systems you should have 65 megabytes of free disk space before attempting to install the JDK software. If you also install the separate documentation download bundle, you need an additional 85 megabytes of free disk space. JDK 1.2 is localized for Japanese.
