代码:

public static boolean isWindows() {
    		return System.getProperty("os.name").toUpperCase().indexOf("WINDOWS")>=0?true:false;	
    	}

扩展:System 中有很多的属性

public static Properties getProperties()

Determines the current system properties.

First, if there is a security manager, its `checkPropertiesAccess` method is called with no arguments. This may result in a security exception.

The current set of system properties for use by the `getProperty(String)` method is returned as a `Properties` object. If there is no current set of system properties, a set of system properties is first created and initialized. This set of system properties always includes values for the following keys:

其中有一个os.name 可以获取当当前使用操作系统的
