Introduction

     Thank you for downloading this release of the Java(TM) Development
     Kit, version 1.2. 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.

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. A 486/DX or faster processor and at least 48
          megabytes of RAM are recommended.  
        * Solaris/SPARC Release. Only Solaris versions 2.5.1, 2.6
          and 7 (also known as 2.7) are 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.  For more information, see
