Command window for java?

Question

Is there a way to just run individual java commands without having to create a file? Kind of like the matlab command window, where you can just type one line and it'll run.

Answer 1

Currently No. Java is not a terminal programming language like matlab and python.

To run java applications, the commands must be compiled

When you compile, the java compiler turns the code into a class file. The class file contains "instructions" for the computer which is the application.

To clarify, Java 9 has JShell, which is a REPL for java. You can find the early access here.

Answer 2

I think what you are looking for is something like this

Sadly it isn't available until java 9, so in its current state it might not be production ready

try is here https://jdk9.java.net/download/

this shows you how to get it going
