Suppose I want to make a Jeroo (named "dave") hop if he is facing west. And, if the Jeroo is not facing west, I want the Jeroo turn to the right. What is the proper way to write this in Java? (Note that some answers may compile, but are not proper.)

if (dave.isFacing(WEST))
{
    dave.hop();
}
else
{
    dave.turn(RIGHT);
}

• if dave.isFacing(WEST)
  {
      dave.hop();
  }
  else
  {
      dave.turn(RIGHT);
  }

• if (dave.isFacing(WEST)
      dave.hop();
  else
      dave.turn(RIGHT);

• if (dave.isFacing(WEST));
  {
      dave.hop();
  }
  else;
  {
      dave.turn(RIGHT);
  }
