How to run jshell when I don't have a file to execute?

Question

I would like to run jshell like this

$ jshell --execute 'System.out.println("Hello World")'
Hello World
$

So it executes the java single code line and terminates. Is it possible?

Answer 1

You can use a pipe:

echo 'System.out.println("Hello World")' | jshell -

From jshell --help :

A load-file may also be "-" to indicate standard input, without interactive I/O.
