Preface
This guide provides information about using the Java Shell tool (JShell) to explore the Java
language and prototype code.
Audience
This document is intended for developers interested in using a Read-Eval-Print Loop (REPL)
tool to learn the Java language, explore new Java APIs and features, and prototype complex
code.

Access to Oracle Support
Oracle customers that have purchased support have access to electronic support through My
Oracle Support. For information, visit http://www.oracle.com/pls/topic/lookup?ctx=acc&id=info

Diversity and Inclusion
Oracle is fully committed to diversity and inclusion. Oracle respects and values having a
diverse workforce that increases thought leadership and innovation. As part of our initiative to
build a more inclusive culture that positively impacts our employees, customers, and
partners, we are working to remove insensitive terms from our products and documentation.
We are also mindful of the necessity to maintain compatibility with our customers' existing
technologies and the need to ensure continuity of service as Oracle's offerings and industry
standards evolve. Because of these technical constraints, our effort to remove insensitive
terms is ongoing and will take time and external cooperation.
