Environment Variables
import java.util.Map; Map<String> env = System.getenv(); // get all environment variables System.getenv("HOME"); // get environment variable "HOME" (returns String, or NULL)NOTE:
java does not let you set environment variables, preferring that you spawn a subshell with a modified environment
Commandline Arguments
Java does not include an argument parser in it's standard library. I recommend apache's java commons cli.
