across multiple platforms. You can run the Java installer on any operating
system, including Windows and Linux. The Java installer requires that you

A JRE (Java runtime environment) is a subset of the components included
in a Java Developer Kit. A JRE contains a JVM and provides the ability to
run Java applications. However, JREs do not include the tools and utilities
necessary to develop applications. If you are planning to develop applications,
you should install a Java Developer Kit.
