QUESTION
I'm working with this molecule found in the the pdb database. https://pubchem.ncbi.nlm.nih.gov/compound/65106
When I go to use the MoltoSMILES module, I'm not getting anything in return, or it seems to inconsistent. Here is my code I use in Jupyter Notebook. Another issue I'm having is minor, but I'd like to use Spyder. I notice the figure never draws in Spyder so I switched to Jupyter. Anyways, here is the code, and I'll show differnt SMILES formats I've either found of generated:

I am working in Java and I want to make a deep copy of a MoleculeDTO object. I tried to make a copy constructor too, but it is not working and it is refering to the initial object.
...ANSWER
Answered 2021-Jun-11 at 22:15Your copy constructors are just doing shallow copies of each field. That's fine for strings because they're immutable, and it's fine for ints because they're primitive (which means they lack identity and are immutable). In those cases, there is no important difference between shallow and deep copies. But it doesn't work in general for lists because lists can be mutable and so can their elements. So instead of just pointing at the same list, you need to make a new list and deep copy each element of the original list into the new one.
Use this helper method to make deep copies of any lists:

QUESTION
I have the following code, which creates a scene and a green rectangle on it (see image below). The problem is, I want the rectangle to stay on its place, when I resize the window, but it moves with it. I don't know where to start: do I need to mess with scene, view, resize event or even rectangle itself? I tried to play with view resize policies, but it had no effect. Thank you in advance!
...ANSWER
Answered 2021-Jun-10 at 03:25You can easily fix this by using view.setAlignment(Qt::AlignLeft | Qt::AlignTop);
, this function will set the alignment of the scene to the top left corner of the QGraphicsView
.
This is what your code should look like.
QUESTION
Have the following case:
...ANSWER
Answered 2021-Jun-08 at 11:46There's a very simple rule in Java: new SomethingOrOther()
will always create a new object (unless it somehow produces an exception).
So the answer is obviously: no, the main
method you posted will create 4 instances of Bond
.
Those instances happen to not have any fields that makes them different in any interesting way, but they are distinct instances.
The reason it "looks like" only one instance exists is that your price
field is static
, which means it belongs to the class Bond
itself and not to an individual instance, which also means there's only one price
ever, no matter how many instances you have (yes, even if there are no instances at all).

QUESTION
Instructions: Create a function expression named searchFirstNames
. The searchFirstNames
function should contain parameters named namesAr
and nameQuery
. Within the searchFirstNames
function implement a .filter method on the array called namesAr
and return an array of names where the first name matches the argument nameQuery
.
Example:
If names array contains the names "Anthony Jackson"
and "Jaco Pastorious"
and the namesQuery
is "Anthony"
then the result of calling the function searchFirstNames
should be an array containing "Anthony Jackson"
Call the function searchFirstNames
with the argument fullNames
and nameQuery
set to be "John"
and store the resulting array into a variable named at your discretion.
My result: So, I called the function searchFirstNames
with the arguments fullNames
and "John"
and I stored the resulting array into a variable called matchingFirstNames
. Unfortunately, matchingFirstNames
comes back as undefined when it should be an array containing "John Smith"
.
