Hi, more details...
lets take a rule like If any 5 students joined in 5 days of span... No Name DOJ 1 A *5/24* 2 B * 5/25* 3 C *5/27* 4 D *5/23* 5 E 5/30 6 F 5/20 7 G 5/15 If we take, A,B,C and D details, these 4 students are joined in <=5 days of span(lowest date :->D:5/23 and highest date :->c:5/27 --> diff is 4 days). If any other student joined in these <=5 days (5/23 to 5/27 ) then we need those all 5 students details. If we take F, A, B and D, these 4 students also joined in <= 5 days...but no.of 5 students condition is missing. As we said we are able to work on static rules like if student joined <=5/23 & !>=5/30 etc. Thanks & Regards Naresh -- View this message in context: http://drools.46999.n3.nabble.com/Comparing-Objects-of-same-class-tp4030073p4030079.html Sent from the Drools: User forum mailing list archive at Nabble.com. _______________________________________________ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
