Part 2: Bug Variations
Methods of the Bug Class
The Bug class provides three methods that specify how bugs move and turn.
public boolean canMove()
tests whether the bug can move forward into a location that is empty or contains aflower
public void move()
moves the bug forward, putting a flower into the location it previously occupied
public void turn()
turns the bug 45 degrees to the right without changing its location
These methods are used in the bug's act method.
Extending the Bug Class
public void act()
{
if (canMove())
move();
else
turn();
}
