13-Jul-15 Getting Ready for Java

2 What You Need 256 MB of RAM (512 MB or more recommended) 500 MHz Pentium or better Macintosh: must run Mac OS X, preferably Panther (10.4) Java JDK 1.5 (includes JRE) Eclipse 3.2 By the way: the JDK and Eclipse are free

3 Getting Java (Windows) Download and install Java JDK Download the JDK, not the JRE If your computer can’t run Java 1.5, get Java [Optional, but strongly recommended] Download the Java 1.5 documentation from the same location

4 Getting Java for Macintosh If you have OS X, you already have Java, but you may not have the latest version Java 5 = Java 1.5 = Java 2 version 5 If you do not have OS X, you have to get it--earlier versions will not run Java 5

5 Getting Eclipse You should have Java installed before you install Eclipse If you Google for “Eclipse”: The first hit is the home page, The second hit is “Eclipse Downloads,” The current version (Sept. 2006) is Eclipse SDK 3.2 Click on the download link Y ou will get a zip file; unzip it No further “installation” is necessary (assuming your Java is installed correctly) Run the eclipse.exe file You will be asked to choose a folder for a “workspace” (mine is called workspace ); do so No further configuration is necessary

6 Vocabulary I JRE, Java Runtime Environment This is the software that allows you to run Java programs on your computer JDK, Java Development Kit (previously called SDK, System Development Kit) The software that allows you to create and run Java programs on your computer When you install the SDK, you get a JRE along with it IDE, Integrated Development Environment A tool that makes it easier to write programs
