Importing custom package into REPL

Complete newbie here. How do I make a custom package/class available in the REPL? I have the following saved in lesson7/Test.scala:

package lesson7

class Test {
val configA = "I am public"
private val configB = “I am private”

I need to make that available with:
scala> import lesson7.Test

Where exactly do I need to save lesson7/Test.scala in order to be able to import it like this?


You compile it and then put the resulting Test.class on the classpath when
you launch scala.

That was helpful. Thank you!

You might want to try the Ammonite REPL ( Its got some nice
features for importing Maven/Ivy artifacts and all transitive dependencies
from within the REPL. Very nice to work with.

$ cat gunk.scala

package gunk

object Main extends App {
  println("hello, world.")


scala> :paste gunk.scala
Pasting file gunk.scala...

scala> gunk.Main main null
hello, world.

In REPL, the distinction is between :load which works like line-by-line input and :paste which accepts package clauses.
