I downloaded Processing for Linux and the one for Mac but both came up with error messages when I open the program icon processing
#!/bin/sh

# installation directory.

# in the download, replace the 'java' folder with the contents of a new
# OpenJDK (Java 11 only), or create a symlink named "java" in the
