Downloading the JDK To compile programs in DrJava, you must make sure you have a Java JDK (Java Development Kit) installed on your machine. All Java distributions available for downloading come in two forms: a JDK and a JRE (Java Runtime Environment). A JDK distribution consists of a JRE distribution (a Java Virtual Machine implementation) plus a collection of development tools including javac, a Java compiler, and javadoc, Java documentation generator. DrJava requires a JDK installation because it uses both javac and javadoc as plugin components. Without these components, DrJava can only edit Java programs; it cannot execute them or generate documentation for them. If you do not have a JDK installed already, you can download one for Windows, Linux, or Solaris computers directly from the Oracle webite.
Apple Macintosh machines running Mac OS X already have a JDK installed. To download a JDK from the Oracle website, just follow these steps!
