17:11 ArslanZ Q: When is it ok to use a singleton pattern?
17:12 ecabrerar @radcortez Does Functional Programming Replace GoF Design Patterns?
17:12 suni nice explanation and easily understand..what ever venkat said about usage of interfa
17:12 sparko joined #virtualJUG
17:12 suni interface
17:12 radcortez cool tks for the questions keep them coming ill ask them right away next

17:16 SJM Venkat is so good :)
17:16 radcortez :)
17:16 suni function<Integer,Integer> inc=e->e+1; is it usage of lambda?
17:16 radcortez yes
17:16 suni ho ok thank u..
17:16 suni can u explain how to will work
17:16 Gadi joined #virtualJUG
17:16 SJM anywhere you see -> is a lambda
17:17 Traivor joined #virtualJUG
17:17 suni e->e+1 how will increment
17:17 suni ?
17:18 Koorva suni go home!
17:18 radcortez suni you can think as a lambda as a shortcut to implement an anonimous inner class
17:18 suni koorva i dont know ,that's why i ask?
17:19 suni koorva if u knew explain..or else your wish
17:19 radcortez so what you have there is actually a interface that receives a number and return a number
17:19 suni radcortez oh..ok thanks a lot
17:19 radcortez but ill ask venkat to showcase it
17:20 Gadi joined #virtualJUG
17:20 sjmaple also, check out some of the previous sessions on the vJUG

17:28 Dmitry joined #virtualJUG
17:29 Guest88331 left #virtualJUG
17:31 ArslanZ Sorry, I didn't quite understand - Why does the facade class need to be a singleton?
17:32 ArslanZ as opposed to being a regular per instance class
17:32 Dmitry There are 23 patterns in GoF? What is the candidate for 24th pattern?
17:32 Shiva joined #virtualJUG
17:33 radcortez give me a sec ArslanZ
17:33 ArslanZ ok
17:35 nabilov joined #virtualJUG

17:37 ecabrerar Great explanations, Venkat.
17:37 ecabrerar You rock!
17:37 radcortez guys keep sending your questions
17:37 srncristea what is the difference between factory method  and abstract factory method ?
17:39 ArslanZ makes sense, Thank you Roberto and Tony!
17:39 srncristea for each module/package worth to have a facade pattern implement ed there  ?
17:40 radcortez ArslanZ: cool :)
17:40 ArslanZ Q: What is the fundamental difference between Factory and Builder patterns?
17:41 ann joined #virtualJUG
17:41 antonmry joined #virtualJUG
17:42 ann When would you use Helper class over Services(or interface)?
17:43 ArslanZ makes sense, thank you!
17:43 Dmitry so factory is a one step builder?
17:44 ArslanZ yes, factory - you give it all the information it needs to instantiate in one call
17:45 ArslanZ (as opposed to builder... as Tony is saying you keep adding elements to it until you are ready to call a final build method which will create the object)
17:46 trayan joined #virtualJUG
17:48 ArslanZ Q: What is the difference between the Facade and the Proxy pattern?
17:50 nabilov joined #virtualJUG
17:51 srncristea in terms of visitor pattern, it's used to separate  a hierarchy  implementation for his behavior , right ?
17:53 Jigar joined #virtualJUG
17:53 ArslanZ Q: This is for Tony & Venkat: Which design patterns  do you see being overly (ab)used?
17:54 ArslanZ And why.
17:54 radcortez thank you so much for all yours questions guys!
17:54 radcortez ill keep relaying them
17:54 jigar1 joined #virtualJUG
17:57 Dmitry Q to Venkat: may passing and returning of functions some spoil encapsulation in terms of java?
17:57 Koorva ivan! zajabis tarka!
