Hey guys, if you want to know which operating system you are using & its version, there are 2 ways to do it as follows;

1. Using Command Prompt

  • Go to Start Menu
  • Go to Run
  • Type cmd & press Enter/return. Command Prompt will open.

Here I have used, ver command one of the DOS commands which returns Name of Operating System and its version.

2. Using Programming

Here we are using a Java Program to find the operating system you are using & its version :
[sourcecode language=”java”]
package com.si.java.utility.os;

public class MyOS
{
public static void main(String[] arg)
{
//To find the name of operating system.
String myOS = System.getProperty("os.name");
System.out.println("Operating System : " + myOS);

//To find the version of operating system.
String myOSVersion = System.getProperty("os.version");
System.out.println("Version : " + myOSVersion);
}
}
