The library accept `Boolean` but I am using `Boolean ` kotlinlang #android

The library accept

Boolean

but I am using

Boolean?

07/15/2018, 2:19 PM

the library doesn’t know how to handle

null

, since it expects

true

false

07/15/2018, 2:22 PM

remove the question mark lol

07/15/2018, 2:31 PM

@rkeazor lol. will it cause any error or inconsistency?

@m1shk4 thanks. just wondering if there is other alternative solution other than remove the question mark.

07/15/2018, 2:33 PM

why would there be a inconsistency. the error says its expecting a boolean, but your giving it a nullable boolean

could you paste a small code sample perhaps

07/15/2018, 2:34 PM

override fun read(`in`: JsonReader?): Response {
        `in`?.beginObject()
        while (`in`?.hasNext()) { << Here is the error
            val token: JsonToken = `in`.peek()
        }
    }

@rkeazor what is the syntax meaning of ``` for the

in

07/15/2018, 2:35 PM

You need a better naming convention

its because in is a kotlin key word

07/15/2018, 2:35 PM

@rkeazor That one is automatic generate by the generator when I hit ALT + Insert to generate the override method.

07/15/2018, 2:35 PM

so it uses the double ticks to specify that your using it to name a vairable

doesn’t matter. just change the name from in, to something more understandble

for instance

07/15/2018, 2:36 PM

So it does not represent anything but to tell the compiler this is a variable name?

07/15/2018, 2:36 PM

jsonReader: JsonReader

07/15/2018, 2:37 PM

Ah! After I change it to reader.

Then it work well.

07/15/2018, 2:37 PM

07/15/2018, 2:37 PM

Now I know why it is

in

Maybe it could be a keyword.

07/15/2018, 2:37 PM

yes its a keyword

07/15/2018, 2:38 PM

So the indicate as

in

to tell the compiler actually this is a variable, not a keyword.

07/15/2018, 2:38 PM

its like naming a variable , when

07/15/2018, 2:38 PM

Great! Thanks @rkeazor!
