JShell in Java 9 - Part 2

Getting Started with JShell: 

Q1. How to Start and Stop JShell?

Open the Jshell from the command prompt in verbose mode. Using this command jshell -v Or jshell.

We will discuss further the difference b/w  jshell and jshell -v command.

Refer the below Image:
















Q2.How to exit JShell?

Just type this command /exit.

Refer the below Image:














Now its time to discuss the difference b/w with -v and without -v.


-v stands for verbose mode. It means in verbose mode we will get the extra information from the Jshell.

Let's see the example in verbose mode and non-verbose mode.

  • Without -v

















  • With -v



Note: If any information displaying on the jshell starts with '|' pipe symbol, it is the information to the programmer from the jshell.

EX:

Refer the below example:

 jshell> System.out.println("Hello World")
 Hello World














  In the above example, we observe that the output does not start with '|' pipe symbol because it is not information from the Jshell.

Note: Terminating semicolons are automatically added at the end of complete snippet by JShell if not entered.
