The question given is "Given the following array declarations, what does the following print" and I thought it would be true, false, true however after copy and pasting the code it reveals the answer is false, false, true. I understand that the == only works when they are the same instance of the object but I do not understand why the first on is false. I tried finding the method in the array api but could not find one with the same arguments. Forgive

Here's the example Fiddle . My goal would be to make sure all the elements have the same height or, at least, the maximum height of the siblings in the row. A row is composed by 3 elements (in this case, no row wrapper exists but I may consider to add such container element). Is there a solution that:

I want to understand the significance of IEqualityComparer<TKey> comparer and what is it actually used for in GroupBy. 回答1: The IEqualityComparer<TKey> object will be used to perform a two-step check to see if a TKey instance is "equal" to the key of an existing

Without constraints I aligned those buttons with 5 space padding with each buttons and each buttons has 50 width. Now,I am trying to make it by using Auto layout to support all Screen sizes. In Storyboard constrains I set equal width for 6 buttons and I made 60 space between each buttons. I set first button 0 to leading space and I set the last button 0 to tail constraints. I want the buttons with equal width and flexible spaces between views

So two entity objects with the same ID would be considered equal. At some point I thought about that and found that two entities in different states should not be considered equal, even when they describe the same thing (i.e. have the same ID). So now I use reference equality for my entities. I then stumbled over this answer by Mark Seemann, where he writes Entities are equal if their IDs equal each other. Now, of course, I'd like to know

Then Visual Studio warned: ... overrides Object.Equals(object o) but does not override Object.GetHashCode() So I then also overrode its GetHashCode() like this: public partial class SomeClass { public override bool Equals(Object obj) { //Check for null and compare run-time types. if (obj == null || this.GetType() != obj.GetType()) return false; return this.Id == ((SomeClass)obj).Id; } public override int GetHashCode() { return this.Id.GetHashCode(); } } It seems to work.

Thanx! 回答1: Yes, that code is valid - if the two classes have been loaded by the same classloader. If you want the two classes to be treated as equal even if they've been loaded by different classloaders, possibly from different locations, based on the fully-qualified name, then just compare

The tkdocs website states as follows: The width of each column (or height of each row) depends on the width or height of the widgets contained within the column or row. This means when sketching out your user interface, and dividing it into rows and columns, you don't need to worry about each column or row being equal width [or height, presumably]. http://www.tkdocs.com/tutorial/grid.html But I want the columns to be equal width, preferably by making the width

Seems all Java bibles say these two MUST be implemented together. :( My concerns: -If I always implement hashCode() together with equals() there will be lots of code not really used, and without unit test covering. (I'm not going to unit test hashCode() if not used) -It's only until when I put the object into a hash based container I know how the objects are intended to be looked up. And only
