                                如何获得 Windows 操作系统的版本
很多时候我们需要知道Windows操作系统的版本,使用下面这个API函数可以做到。
Option Explicit
Private Declare Function GetVersionEx Lib "kernel32" Alias "GetVersionExA" (lpVersionInformation As OSVERSIONINFO) As ...
                            
                            
                         
                    
                        
                            
                            
                                通过Mahout构建推荐系统时,如果我们需要加入某些过滤规则(比如:item的创建时间在一年以内),则需要用到IDRescorer接口,该接口源码如下:
package org.apache.mahout.cf.taste.recommender;
/**
