Java Program to determine the name and version of the operating system

In this article, we will understand how to determine the name and version of the operating system. This is accomplished using System.getProperty function. The getProperty(String key) method in Java is used to returns the system property denoted by the specified key passed as its argument.It is a method of the java.lang.System Class.

Below is a demonstration of the same −

Input

Suppose our input is −

Run the program

Output

The desired output would be −

The operating system being used in the system is : Mac OS X

Algorithm

Step 1 – START
Step 2 – Declare a string namely my_os
Step 3 – Call the function System.getProperty to fetch the details of operating system and
store it in a string
Step 4 – Display the result
Step 5 – STOP

Example 1

public class OperatingSystem {
   public static void main(String[] args) {
      String my_os = System.getProperty("os.name");
      System.out.println("The operating system being used in the system is : " +my_os);
   }
}

Output

The operating system being used in the system is : Linux

Example 2

public class OperatingSystem {
   public static void main(String[] args) {
      String my_os = System.getProperty("os.name");
      System.out.println("The operating system being used in the system is : " +my_os);
   }
}

Output

The operating system being used in the system is : Linux
