Explanation:
Double dribble, traveling, and stepping out of bounds are all violations.
Double dribble is when when you dribble, stop for whatever reason, and begin dribbling again.
Traveling is when you stop dribbling the ball and continue to run/walk/jog with it in hand. You have to stop moving if you stop dribbling.
Out of bounds is out of the line boundaries.
