  Using correct assertions here isn't more difficult:

      »Simple statements end in a semicolon.
      The block is a compound statement.
      A while loop might execute its statement several times.«

  The while loop already is a more complex statement. If the
  audience consists of absolute beginners in programming, it
  might appear too early in the book.

  In my classes, I take some time to introduce simple statements
  (expression statements) and blocks and then do several
  exercises related to them, so that everyone gets a firm grip
  of these concepts. So there is no need to make false claims.
  I even discuss the false belief that »all statements end in
  a semicolon« in an exercise, where the pupils are asked to
  review this statement.

  I often do not treat loops at all, or only when asked about
  them. For the audience I encounter when I am giving adult
  evening classes about Java, this book already is too fast and
  thus too difficult.
