Understanding recursion [closed]
... right child, before we did that we recursed the left child.
In fact, the order in which we called the children, and added the current node's value didn't matter at all, because addition is commutative.
Now let's look at an operation where order does matter. We'll use a binary tree of nodes, but t...

The order is:
Member variables are initialized to default values for all classes in the hierarchy
Then starting with the most derived class:

Difference between JSONObject and JSONArray
...gt;value pairs, tuples or whatever you want to call them)
like {ID : 1}
Order of elements is not important
a JSONObject of {id: 1, name: 'B'} is equal to {name: 'B', id: 1}.
JSONArray:
Contains only series values
like [1, 'value']
Order of values is important

log4j logging hierarchy order
... Although this answers the question (that's just asking for the "hierarchy order"), I finally downvoted for your poor terminology: going down, "visibility" works, item. Didn't you wish to explain how logger configuration affects the actual logging (passing log events)? Please consider another update...
Quicksort vs heapsort
... Quicksort. Heapsort doesn't need more memory for another array to putting ordered data as is needed by Mergesort. So why do comercial applications stick with Quicksort? What Quicksort has that is so special over others implementations?
I've tested the algorithms myself and I've seen that Quicksort...
How to preserve insertion order in HashMap? [duplicate]
...en I iterate over the map, the data is returned in (often the same) random order. But the data was inserted in a specific order, and I need to preserve the insertion order. How can I do this?

Call a Server-side Method on a Resource in a RESTful Way
... (i.e., so that intermediaries don’t have to
know the resource type in order to understand the meaning of the
request).
In the above examples, POST is uniformly designed. It will make the dog "bark". That is not safe (meaning bark has effects on the resources), nor idempotent (each request y...

...eType.REMOVE and orphanRemoval=true.
For orphan removal:
If you invoke setOrders(null), the related Order entities will be removed in db automatically.
For remove cascade:
If you invoke setOrders(null), the related Order entities will NOT be removed in db automatically.

Check if two lists are equal [duplicate]
...
var a = ints1.SequenceEqual(ints2);
Or if you don't care about elements order use Enumerable.All method:
var a = ints1.All(ints2.Contains);
The second version also requires another check for Count because it would return true even if ints2 contains more elements than ints1. So the more correct...
