Cannot create package IntelliJ IDEA
(3 answers)
Closed 6 months ago.
When I add a folder called "interface" in my Scala project in IntelliJ IDEA,
there is a error: "Not a valid package name".
Why is this and is this possible to change?
You can't use reserved keywords.
see the list of reserved keywords:

whats syntax for calling other scenario in same feature file?
(1 answer)
Closed 1 year ago.
demoType is a variable and I want the content of this variable to be what is evaluated in the following expression:
* def call read(demoType)
On the contrary, it tries to evaluate the name of the variable and not its content.
There is no such thing as def call.
Maybe you were trying:
* call read(demoType)
Or:
* def temp = call read(demoType)
Make sure you are on the latest version of Karate. And read the docs: https://github.com/intuit/karate#call-vs-read

ArrayList<String>() vs arrayListOf<String>()
(5 answers)
Closed 3 years ago.
I searched the difference between arrayListOf and ArrayList.
so I understand arrayListOf is function, and ArrayList is class.
but I don't understand the exact difference using them.
As described in the documentation arrayListOf is a function that creates an ArrayList instance. If I understand it correctly it serves the purpose of determining the generic type from the passed input values and it's a convenience function.

Confused about Swift Array Declarations
(2 answers)
Closed 5 years ago.
I was wondering what is the better way to declare variables?
private var arrayOfStrings: [String] = []
or
private var arrayOfStrings = [String]()
What are the advantages/disadvantages of either solution?
Thanks
As noted here there are little differences in the 2 ways.
Using type annotation you declare which type the variable is, while not using it you let Swift infer the type of the variable.
Almost always Swift will infer the correct type. Be careful:
As you can encounter situations like this in which Swift will have a decision to take. Read the full documentation here.

Access variables and functions defined in page context using a content script
(6 answers)
Closed 7 years ago.
How can I inject a <script> to my document which will initialize a variable?
content_script:
$("body").append('<script type="text/javascript">myvar="hi there";</script>');
When I do this, the variable myvar is not recognized...
If I add a simple alert(500); I get the alert.
Basically I just want to pass a variable from the extension the document to use it there.
add var
$("body").append('<script type="text/javascript">var myvar="hi there";</script>');

Method overloading in Objective-C?
Is method overloading not possible.
I have two functions with the same name.
When declared like the below i'm etting errors.
-(RS232Msg*)CreateMessage:(REMOTE_MESSAGE_ID) nMessageNumber;
-(RS232Msg*)CreateMessage:(const uint8_t*) szMessageName;
when declared -(RS232Msg*)CreateMessage:(const uint8_t*) szMessageName; i'm not getting any errors.
I also have two functions as the same name with different return type and argument.But its working fine and there is no error in its declaration.
Why is it so?
No, method overloading is not possible in C, and therefore not possible in Objective-C (since Objective-C is a superset of C). If you'd like to use those two methods, you'll have to change their names. I would suggest the following:
- (RS232Msg *)createMessageWithMessageID:(REMOTE_MESSAGE_ID)nMessageNumber;
- (RS232Msg *)createMessageWithName:(const uint8_t*)szMessageName;
