How do I programmatically determine operating system in Java?

Question

I would like to determine the operating system of the host that my Java program is running programmatically (for example I would like to be able to load different properties based on whether I am on a Windows or Unix platform). What is the safest way to do this with 100% reliability?

Answer 1

You can try this Syntax:

System.getProperty("os.name")

Example:

class ShowProperties {

    public static void main(String[] args) {

        System.getProperties().list(System.out);

    }

}

This code print out all the properties stored by your Java implementations. It'll give you a notion of what you can get out of your Java environment via properties.
