read-eval-print loop (REPL) for several languages

Question

I was wondering if there are some recommended read-eval-print loop (REPL) respectively for

(1) C++

(2) C

(3) Java

Thanks!

Answer 1

C and C++

You can use CERN's cint.

Java

You can use BeanShell, or if you don't care so much about having Java syntax (e.g. your goal is just to make sure the classes do what you want), you can use Groovy, Scala, JRuby, or Jython.

Answer 2

Those aren’t languages that support a dynamic eval function.

Answer 3

There is also a Java REPL using the javax.tools.JavaCompiler interface here: http://www.scravy.de/blog/2012-02-27/a-read-eval-print-loop-for-java.htm (runs on the command line).

Answer 4

This seems to be avalaible in Java 9 coming september 22 of 2016.
