java - How to encapsulate a Map into a custom object -


My coworker tells me that it is lazy to use sloppy, and that many times the purpose of the programmer will be to provide better service through a real object. But I do not know the best way to do this. This fact is even more complex (me) that the key is an enum type.

Say I have a hashmap , which is expected to be in the four hashish keys (one for each value in MyEnum ). MyObj Hashp Value is the latest of many MyObjs in a database, which contains the enum values ​​given.

My best estimate includes an object with four fields, or two arrays with keys and values ​​in sequence.

Obviously whether it is clear or not (this is 5 PM on Thursday = I'm brain-dead), so if necessary, please ask for clarification. Although there is nothing wrong in using the map for your desired purpose, the map is sometimes incorrect, Type objects 

  string firstname = (string) myMap.get ("first_name"); Unlike

... ... 

  string first name = person.getFirstName ();

Because Java classes implement AIIMS, you may want to consider putting that value which you are looking directly in your enum class:

< Pre> MyEnum val = getVal (); My obz = vow Getrest Reese My Obze ();

But I want to focus on separating the concerns for deciding whether this really makes sense or not. It may well be that the map for this job is a suitable device.

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
