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.
