What are the three fouls that can occur when the javelin?

The three fouls that can occur when throwing the javelin are stepping out of the throwing area, failing to release the javelin before crossing the front edge of the throwing arc, and the javelin landing outside the designated sector. A throw is considered a foul if the athlete touches the ground outside the throwing area during their attempt. Additionally, if the javelin does not land within the marked sector, the throw is also invalidated.
