I have a simple toy project made of two classes:
object A {
var b = B()
}
class B {
....
}
I cannot use any IDE, because I need to use ssh.
I cannot compile the project because of the error:
A.scala:18: error: not found: value B
I compile using:
scalac *.scala
I tried to play around with the classpath but that did not solve.
Can you help me?
Since you haven't defined a companion object for B, when you instantiate it, you need new B() instead of just B().
If you want to instantiate class B by using var b = B(), you'll need to create a companion object for class B with an apply() factory method:
class B {
// ...
}
object B {
def apply(): B = new B()
}
Note that B() is special syntax for B.apply().
Another way is to make B a case class:
case class B {
// ...
}
Then a companion object with an apply method is automatically generated (as well as a toString and methods for pattern matching).
