You can always use Java to call the Windows command 'systeminfo' then parse out the result, I can't seem to find a way to do this natively in Java.

您始终可以使用 Java 调用 Windows 命令“systeminfo”，然后解析结果，我似乎找不到在 Java 中本地执行此操作的方法。

 import java.io.*;

   public class GetWindowsEditionTest
   {
      public static void main(String[] args)
      {
         Runtime rt; 
         Process pr; 
         BufferedReader in;
         String line = "";
         String sysInfo = "";
         String edition = "";
         String fullOSName = "";
         final String   SEARCH_TERM = "OS Name:";
         final String[] EDITIONS = { "Basic", "Home", 
                                     "Professional", "Enterprise" };

         try
         {
            rt = Runtime.getRuntime();
            pr = rt.exec("SYSTEMINFO");
            in = new BufferedReader(new InputStreamReader(pr.getInputStream()));

            //add all the lines into a variable
            while((line=in.readLine()) != null)
            {
               if(line.contains(SEARCH_TERM)) //found the OS you are using
               {
                //extract the full os name
                  fullOSName = line.substring(line.lastIndexOf(SEARCH_TERM) 
                  + SEARCH_TERM.length(), line.length()-1);
                  break;
               } 
            }

            //extract the edition of windows you are using
            for(String s : EDITIONS)
            {
               if(fullOSName.trim().contains(s))
               {
                  edition = s;
               }
            }

            System.out.println("The edition of Windows you are using is " 
                               + edition); 

         }
            catch(IOException ioe)      
            {   
               System.err.println(ioe.getMessage());
            }
      }
   }

You can use the Apache Commons Library

您可以使用Apache Commons 库

The class SystemUtils provides several methods to determine such information.

SystemUtils 类提供了多种方法来确定此类信息。

You can get a lot of information about the System you're running on by asking the JVM about it's System Properties:

通过向 JVM 询问系统属性，您可以获得有关正在运行的系统的大量信息：

import java.util.*;
public class SysProperties {
   public static void main(String[] a) {
      Properties sysProps = System.getProperties();
      sysProps.list(System.out);
   }
}

EDIT:the property os.nameseems to be your best bet

The results from System.getProperty("os.name")vary between different Java virtual machines (even the Sun/Oracle ones):

System.getProperty("os.name")不同 Java 虚拟机（甚至是 Sun/Oracle 虚拟机）的结果不同：

A JREwill return Windows 8for a windows 8 machine. For the same system a Windows NT (unknown)is returned when running the same program with a JDK.

AJRE将返回Windows 8Windows 8 机器。对于相同的系统，Windows NT (unknown)当运行带有JDK.

System.getProperty("os.version")seems more reliable on this. For Windows 7it returns 6.1and 6.2for Windows 8.

System.getProperty("os.version")在这方面似乎更可靠。因为Windows 7它返回6.1并且6.2对于Windows 8.

public static void main(String[] args) {
    System.out.println("os.name: " + System.getProperty("os.name"));
    System.out.println("os.version: " + System.getProperty("os.version"));
    System.out.println("os.arch: " + System.getProperty("os.arch"));
}

output:

输出：

os.name: Windows 8.1
os.version: 6.3
os.arch: amd64
