Java custom optional values for constructor -


This code is too much for me to do: 

  import java.util Random; Public class testclass (protected intestine test; Protected Ent TestWeb; Public Test Class () {Random R = New Random (); This (r.nextInt (), r.nextInt ()); } Public Test Class (Int TestVara, Int TestWeb) {this.testVarA = startTestVarA; This.testVarB = startTestVarB; }}

However, it does not compile, because this () statement should be next to the function. I can do something like this. (New Random ()) GetNextInt (), (New Random). GetNextInt ())

But it seems very unfair. What is the right way to do this?

You can move complex initial arguments in a different way: 

  public test class () {random R = new random (); Init (r.nextInt (), r.nextInt ()); } Public Test Class (Int TestVarva, Int TestWeb) {init (Testwada, TestWarb)} Private Zero Init (Int TestVara, Int TestWeb) {this.testVarA = startTestVarA; This.testVarB = startTestVarB; }

This is a more general solution than being a field as random . In this special case, the random field works because the class In all the instances of this, it can be shared without side effects, but if you want to do something that is not as thread-safe as a beginner, then it may become a problem about not being eligible for garbage collection. Here in Not to talk about the static field. ever

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
