What is a JShell in Java 9

JShell is an interactive command-line tool introduced in Java 9 that allows developers to evaluate Java expressions, run Java statements, and test Java code snippets quickly without the need to create a full Java program. It provides an easy way to experiment and learn Java programming by allowing immediate feedback on the code entered.

// Example of using JShell jshell> int a = 5; jshell> int b = 10; jshell> System.out.println(a + b); 15
