In the previous chapter, we examined Java Shell (JShell), Java 9's new read-eval-print loop (REPL) command-line tool. We started with introductory information regarding the tool and looked closely at the read-eval-print loop concept. We spent considerable time reviewing JShell commands and command-line options. Our coverage included practical guides to feedback modes, asset listing, and editing in the shell. We also gained experience working with scripts.

Lastly, we will look at some garbage collection issues that persist, even after Java 9.
The following topics are covered in this chapter:
