Friendly supplies a new text() body. The first call is made through a Greeting variable but still dispatches to the Friendly implementation.

class Greeting {
  public String text() { return "hello" }
}

class Friendly extends Greeting {
  public String text() { return "hi" }
}

main() {
  Greeting greeting = Friendly()
  printLine(greeting.text())
  printLine(Friendly().text())
}

Expected output:

hi
hi

Try it: Replace Friendly() with Greeting() in the first assignment.
