How to use JShell with NetBeans?
JShell or Java Shell is a Read-Evaluate-Print Loop (REPL). This means it evaluates expressions as and when they are entered and shows us the results. JShell can be accessed from the command line and is an excellent tool to make adjustments to your code. A basic Java program needs you to go through the tedious process of writing a complete program before compiling it, fixing the errors, running it only to find that the output is not what you expected. Using a JShell helps you find problems as and when you’re developing code. You can run individual statements in a JShell and use APIs you have no idea about.
