Example: Determine the Operating System
class Main {
public static void main(String[] args) {
// get the name of operating system
String operatingSystem = System.getProperty("os.name");
System.out.println(operatingSystem);
}
}
Output
Windows 10
In the above example, we have used the getProperty() method of the System class. Here, we have passed the os.name key as an argument to the method.
The method returns the property of the system specified by the key.
There are other keys that can be used to get other system properties. For example,
// returns the version of Operating system
// 10.0
System.getProperty("os.version");
Here, the key os.version returns the version of the operating system.
