Summary


In this chapter, we explored potential issues involved in migrating our existing applications to the Java 9 platform. We looked at both manual and semi-automated migration processes. This chapter provided you with insights and processes to get your Java 8 code working with Java 9. Specifically, we conducted a quick review of Project Jigsaw, looked at how modules fit into the Java landscape, provided tips for migration planning, shared advice from Oracle regarding migration, and shared tools that you can use to help you as you get started with Java 9.

In the next chapter, we will take a close look at the Java shell and the JShell API. We demonstrate the JShell API and the JShell tool's ability to interactively evaluate declarations, statements, and expressions of the Java programming language. We will demonstrate features and use of this command-line tool.
