inheritance - Java one child class containing other siblings -


I saw that some code has a child in which there are other siblings, for example, in the below Child1 Brother-Sister Child 2, Child 3 are included. I wonder if there is a problem in this design? 

  Public Class Parents {...} Public Ultimate Classroom Child1 Parents Detail (Private Child 2 Children 2; Private Child 3 Children 3; ...} Public Finals Class Child2 Mothers- Expanding the father {...} Public Final Class Child3 Parents Expansion ... Itemprop = "text"> 
 There is nothing wrong with the code posted by you technically, but let me The question arises whether this is the right way to model your domain. Does it make sense to talk to children 1 and Child3 from the point of view? Or is this just a way to divide your code into logical classes?  
 In addition to this, The tree should be avoided where the legacy is probably the strongest form of coupling. Perhaps you can apply the same functionality by using the strategy method to reduce coupling.

c - Mpirun hangs when mpi send and recieve is put in a loop -

I was trying to use the program to use mifrewan on 4 node clusters. Distributing node 0 data in nodes 1, 2 and 3. In the program, from '90 'to variable values ​​of' dior 'to be calculated. Therefore the node is distributing data and collecting results in an omitted fashion (for different values ​​of var 'dir') when do {*******} Whereas (dir Loop is given, Mippun is hanging, and no output is found. But when I comment on two {*******} (dir The loop output is obtained for the initial value of variable dir dir = -90 ), and that output is correct. The problem occurs when the loop is given. Can anyone help me in solving this problem. #include "mpi.h" int main (int argc, char * argv []) Float dir = -90; Int rank, nanoprakash; MPI_Status status; MPI_Init (& amp; argc, & argv); MPI_Comm_rank (MPI_COMM_WORLD, & amp; Rank); MPI_Comm_size (MPI_COMM_WORLD, & amp; numprocs); If (rank == 0) {/ / data to begin / / (dest = 1; dest ...

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
