Apriori 算法 Java實(shí)現(xiàn)

1、Apriori 算法 Java實(shí)現(xiàn),使用到Hibernate3.2,JUnit4.X開源框架,此算法完全可以應(yīng)用到課程設(shè)計(jì)和畢業(yè)設(shè)計(jì)上，如果做得好打“優(yōu)”基本上是沒問題， 具體算法實(shí)現(xiàn)如下： 1， 這個(gè)測試類用于初始化數(shù)據(jù)表中的數(shù)據(jù)： /* * 這個(gè)測試類用于初始化數(shù)據(jù)表中的數(shù)據(jù) * author 朱志強(qiáng)（ZZQ） * */public class InitialData  private static Configuration cfg = null;  private static
