DrJava for Home

To use DrJava, you also need to install Java 7, specifically you need to install the Java 7 JDK (Java SE Development Kit).  If DrJava complains that you don't have a compiler, that is because you have not installed the Java 7 JDK.  Both Java 7 and DrJava are available at no cost.  If you wish to obtain copies and install them on your home machine, follow these steps.

• Obtain the Software


• You can download Java 7 from the Oracle Java web site or you can get a copy here (or the 32-bit version).
• You can download DrJava from the DrJava web site or you can get a copy here.


• Install Java 7


• To use DrJava, you need to install Java 7.
• Download a copy of the latest JDK onto your desktop.  [If you download Java 7 from the Sun Java web site, it should have a name like jdk-7u25-windows-x64.exe.]
• Double-click on the JDK.  Do not blindly follow the recommended installation because you likely do not want the Ask Toolbar or the McAfee Security Scanner.


• Install DrJava


• Put a copy of drjava-stable-20120818-r5686.exe on your desktop.
• Double-click on the icon to start DrJava.
• DrJava documentation is available at the DrJava web site.
