Intersect on ArrayList with objects groovy -


I have two array lists with items of domain category 'user' 

  a = [User: 35, User: 36] User: 37] b = [user: 32, user: 33] user: 34, user: 35, user: 36, user: 37]
< P> When I do intersection ( java.util ), it returns an empty list. How can I get general objects in the array list?

This is due to the fact that you map (with the same key in the list.

[user4: 32], user 5: 33, user 6:

34, User 1: 35, User 2: 36, User 3: 37] ActorsAct (B) == [Users 1: 35, User 2: 36, User 3: 37]

When you modify it to include the ID, it behaves as expected: 

  def a = [35, 36, 37] def b = [ 32, 33, 34, 35, 36, 3 7] An underlying pointer (B) == [35,36,37]

See this?

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ
