As the title suggests, this is a presentation all about our experiences with JShell (aka the Java Shell Tool), a powerful Read-Evaluate-Print-Loop (REPL) tool available in Java Development Kit (JDK) since version 9. Many languages contain such a command-line REPL tool that evaluates declarations, statements, and expressions as they are entered and immediately shows the results, and now we have one in Java. JShell introduces a full-fledged yet straightforward REPL to Java, useful in many cases, from learning new Java language features or APIs, through quick prototyping and debugging without the need for developing complex classes, all the way to educational purposes in introductory programming courses in online courses and at colleges and universities. Together with vars introduces in JDK 10, JShell became even easier to use and can be immensely helpful for trying some new functionalities or running a smaller project's parts. With JShell developers, educators, and students can quickly run some code without starting a full-blown IDE and/or creating a new project; however, JShell can also be used as an addition to IntelliJ IDEA, Eclipse, NetBeans or elsewhere. We intend to reveal to you some of the great usages of JShell related to support for prototyping and learning.
