下面是一些简短、简洁(并且热切地计算过)的顶级答案:

switch(OSType.DETECTED){
...
}

helper enum:

public enum OSType {
    Windows, MacOS, Linux, Other;
    public static final  OSType DETECTED;
    static{
        String OS = System.getProperty("os.name", "generic").toLowerCase(Locale.ENGLISH);
        if ((OS.contains("mac")) || (OS.contains("darwin"))) {
            DETECTED = OSType.MacOS;
        } else if (OS.contains("win")) {
            DETECTED = OSType.Windows;
        } else if (OS.contains("nux")) {
            DETECTED = OSType.Linux;
        } else {
            DETECTED = OSType.Other;
        }
    }
}

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));
    }
}

你可以使用sun.awt.OSInfo#getOSType()方法

我认为下面的内容可以用更少的字里行间覆盖更广的范围

import org.apache.commons.exec.OS;

if (OS.isFamilyWindows()){
                //load some property
            }
else if (OS.isFamilyUnix()){
                //load some other property
            }

获取操作系统名称，只需使用:

Platform.getOS()

假设你想看看平台是否是linux:

if (Platform.getOS().equals(Platform.OS_LINUX)) {
}

类似地，Platform类为其他操作系统名称定义了常量。平台类是org.eclipse.core.runtime包的一部分。

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"));
    }
}
