How to add an environment variable in Java? [duplicate]

Answer 1

You can get the environment variable with the process Builder object :

    ProcessBuilder pb = new ProcessBuilder("myCommand", "myArg1", "myArg2");
    Map env = pb.environment();
    env.put("VAR1", "myValue");
    env.remove("OTHERVAR");
    env.put("VAR2", env.get("VAR1") + "suffix");
