You just need a JRE. The JDK will be helpful for troubleshooting as it contains a few tools that help in that regard. But operationally, just the JRE is needed. ---

Joshua, Could you please elaborate more on these? What you mean by "JDK will be helpful for troubleshooting as it contains a few tools that help in that regard"? And what you mean by "But operationally, just the JRE is needed"? ---

The JDK contains the JRE, plus additional tools and components that are useful for debugging and troubleshooting, in addition to being necessary for doing development work in Java. To just run a Java program, you only need the JRE. See also the first few sections from [Oracle's Java platform overview](https://docs.oracle.com/javase/8/docs/technotes/guides/). ---
