下面的代码显示了你可以从System API得到的值，这些都可以通过这个API得到。

public class App {
    public static void main( String[] args ) {
        //Operating system name
        System.out.println(System.getProperty("os.name"));

        //Operating system version
        System.out.println(System.getProperty("os.version"));

        //Path separator character used in java.class.path
        System.out.println(System.getProperty("path.separator"));

        //User working directory
        System.out.println(System.getProperty("user.dir"));

        //User home directory
        System.out.println(System.getProperty("user.home"));

        //User account name
        System.out.println(System.getProperty("user.name"));

        //Operating system architecture
        System.out.println(System.getProperty("os.arch"));

        //Sequence used by operating system to separate lines in text files
        System.out.println(System.getProperty("line.separator"));

        System.out.println(System.getProperty("java.version")); //JRE version number

        System.out.println(System.getProperty("java.vendor.url")); //JRE vendor URL

        System.out.println(System.getProperty("java.vendor")); //JRE vendor name

        System.out.println(System.getProperty("java.home")); //Installation directory for Java Runtime Environment (JRE)

        System.out.println(System.getProperty("java.class.path"));

        System.out.println(System.getProperty("file.separator"));
    }
}

我发现Swingx的操作系统Utils可以完成这项工作。

你可以使用sun.awt.OSInfo#getOSType()方法

上面答案中的一些链接似乎被打破了。我在下面的代码中添加了指向当前源代码的指针，并提供了一种方法来处理以enum作为答案的检查，以便在计算结果时使用switch语句:

OsCheck.OSType ostype=OsCheck.getOperatingSystemType();
switch (ostype) {
    case Windows: break;
    case MacOS: break;
    case Linux: break;
    case Other: break;
}

helper类是:

/**
 * helper class to check the operating system this Java VM runs in
 *
 * please keep the notes below as a pseudo-license
 *
 * http://stackoverflow.com/questions/228477/how-do-i-programmatically-determine-operating-system-in-java
 * compare to http://svn.terracotta.org/svn/tc/dso/tags/2.6.4/code/base/common/src/com/tc/util/runtime/Os.java
 * http://www.docjar.com/html/api/org/apache/commons/lang/SystemUtils.java.html
 */
import java.util.Locale;
public static final class OsCheck {
  /**
   * types of Operating Systems
   */
  public enum OSType {
    Windows, MacOS, Linux, Other
  };

  // cached result of OS detection
  protected static OSType detectedOS;

  /**
   * detect the operating system from the os.name System property and cache
   * the result
   * 
   * @returns - the operating system detected
   */
  public static OSType getOperatingSystemType() {
    if (detectedOS == null) {
      String OS = System.getProperty("os.name", "generic").toLowerCase(Locale.ENGLISH);
      if ((OS.indexOf("mac") >= 0) || (OS.indexOf("darwin") >= 0)) {
        detectedOS = OSType.MacOS;
      } else if (OS.indexOf("win") >= 0) {
        detectedOS = OSType.Windows;
      } else if (OS.indexOf("nux") >= 0) {
        detectedOS = OSType.Linux;
      } else {
        detectedOS = OSType.Other;
      }
    }
    return detectedOS;
  }
}

此代码用于显示有关系统操作系统类型、名称、java信息等的所有信息。

public static void main(String[] args) {
    // TODO Auto-generated method stub
    Properties pro = System.getProperties();
    for(Object obj : pro.keySet()){
        System.out.println(" System  "+(String)obj+"     :  "+System.getProperty((String)obj));
    }
}

在com.sun.jna.Platform类中，您可以找到有用的静态方法，例如

Platform.isWindows();
Platform.is64Bit();
Platform.isIntel();
Platform.isARM();

还有更多。

如果使用Maven，只需添加依赖项

<dependency>
 <groupId>net.java.dev.jna</groupId>
 <artifactId>jna</artifactId>
 <version>5.2.0</version>
</dependency>

否则，只需找到jna库jar文件(例如jna-5.2.0.jar)并将其添加到类路径。
