This code example shows how to display the current user logged on to the computer.
There is a system property called 'user.name' which holds the value of the current user. The property is obtained by calling the getProperty() method of the System class.

/**
*
* @author www.javadb.com
*/
public class Main {

    public void getCurrentUser() {

        String currentUser = System.getProperty("user.name");
        System.out.println("Current user is " + currentUser);
    }
    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        new Main().getCurrentUser();
    }
}
