    Default Envrionment Variable & Properties

    I was doing a program asking the following: Write a Java program to get the value of the environment variable USERNAME.

    Si I wrote the following code :

    // getting username using System.getProperty in Java
            String user = System.getProperty("user.name");
            System.out.println(user); //print sid

    After checking solution of exercise they wrote the following code :

    // get the value of the specified environment variable USERNAME
            System.out.println(System.getenv("USERNAME")); // print null

    My question is what is the difference between environment variable and property?

    I did but I want to have someone else explanation. I got my own understanding but it seems not that good since what I suggested as an answer (my code) is not correct

    What did you get from Google for explanations of those two areas?
