As the title says, is it possible to use a java variable in a scala file?
Say I have two files, java1.java and scala1.scala in the same folder.
java1.java file,
public class java1{
public static void main(String[] args) {
String a = "Hello";
}
}
scala1.scala file,
object scala1 extends App {
val b: String = a // a is the variable from java1.java
}
a is a local variable. It is local to the scope it is defined in, in that case the method java1.main. (That's why it's called a "local" variable, after all!)
You cannot even access this variable in a different method of the same file, let alone a completely different object.
This has nothing to do with Scala vs. Java. This is true for pretty much every programming language ever created.
