I want to create an array in which would contain objects of an class and with size 10 but first I want to declare it globally without any entries in array and later on use a function to entry it. Is it possible in kotlin and what is the syntax

[gian]

arrayOfNulls<YourType>(10)

Thanks

[gian]

Also, the docs about this stuff: https://kotlinlang.org/docs/reference/basic-types.html#arrays

[jimn]

as it happens this must be a nullable type, right?

[gian]

Yes, otherwise you need to initialize each value

[Ashutosh Panda]

so now if I entered first entry will it be null?

[gian]

Array(10) { i -> YourType() }

[diesieben07]

YourType doesn't have to be nullable, but the resulting array will be Array<YourType?>

[diesieben07]

So the elements can be null

[Ashutosh Panda]

Type is a class

[Ashutosh Panda]

so will it work

[jimn]

this makes it impossible to get Array<T>(10) from an empty array but it seems easier sometimes to do something.map{}.toTypedArray()

[jimn]

it will convert an arraylist for you without T? down the line
