• This program is used to find out and print the name and version of the operating system that Java uses to execute its programs.
• A method getProperty() of the class System in Java takes the key os.name as its parameter and stores the value in a string variable OperatingSystem.
• The method getProperty() simply returns that property of the system which is specified by the key in its parameter.      
•  In this case of the key os.name, the method returns the name of the operating system i.e. Windows 10.
• The version of the operating system can also be determined by simply changing the key inside the getProperty() method to os.version as follows: System.getProperty(“os.version”).
