CodeHS supports many programming languages and versions on our platform. You can learn more about CodeHS program types in this related article: Program Types
On any CodeHS exercise or Sandbox program, you can see additional information about the language and version by going to More > About:
Below is some general information about the versions of programming languages you will find in CodeHS courses and Sandbox programs.
Current CodeHS courses use: Python 3
Courses created prior to 2020 used: Python 2.7
The CodeHS Sandbox also supports graphics programs using Tkinter, Brython (version 3.9.0 or 3.11.0), and Pygame. Explore all the different types of Python programs supported by the Sandbox here. See Using the CodeHS Editor to learn how to change Brython versions.
Main CodeHS courses use: Java 8 / 1.8
CodeHS now supports Java 11 and the ability to switch between versions of Java. To switch between versions, you can create a file named “run.sh” that uses the jenv command.
To learn more about the
run.sh file, check out this tutorial:
CodeHS Tutorial: run.sh
To learn more about using Java 11, check out this demo and short video:
CodeHS supports JShell, an interactive Java REPL (read-eval-print-loop). In JShell you can explore the Java language without compiling an entire program. Running a JShell uses a 'run.sh' file.
