Java Program to Get the Name and Version of the Operating System

Java Examples Comprehensive

In this example, we will learn how to use Java programs to get the current name and version of the operating system.

Example: java getting the name and version of the operating system

class Main {
　　public static void main(String[] args) {
　　　　//Get the name of the operating system
　　　　String operatingSystem = System.getProperty("os.name");
　　　　System.out.println(operatingSystem);
　　}
}

Output Result

Windows　10

In the above example, we used the getProperty() method of the System class. Here, we pass the os.name key as a parameter to this method.

This method returns the system property specified by the key.

There are other keys that can be used to obtain other system properties. For example,

//Returns the version of the operating system
//　10.0
System.getProperty("os.version");

Here, the key os.version returns the version of the operating system.
