How can I declare a variable globally in Kotlin such that a variable declared in Class A can be accessed in Class B?
val fpath: Path = Paths.get("")
I want to be able to access the variable fpath throughout the entire program/project.
P.S. I am new to Kotlin. Any help would be appreciated.
First: Accessing a property of another class isn’t hard as long as it’s visibility allows it. By default, without explicit visibility modifier, it is:
class A{
val fpath= ...
}
class B(val a: A){
fun xy() = print(“accessing property of A: ${a.prop}”)
}
Second: What you should rather do with your example variable fpath is defining it as a top-level element, i.e. directly in a file, which can be accessed from anywhere else by simply importing the element.
For example, you could have a Common.kt file in package com.x with fpath = Paths.get(...) in it. From another file you do import com.x.fpath and use it throughout the file.
Third: You could also define the variable in a companion object of A if it belongs there:
class A {
companion object {
val fpath = ...
}
}
class B{
fun xy() = print(“accessing property of A: ${A.fpath}”)
}
