I found this on globalsecurity :
"The F-22 has an arresting hook in an enclosed fairing between the engines on the underside of the aircraft. This hook is deployed in an emergency
to stop the aircraft by means of hooking on to a wire strung out across the end of a runway. These barrier engagements work very similar to the
arresting gear of an aircraft carrier.
While the F-22 has an arresting hook, it cannot land on an aircraft carrier, as the F-22 does not have the heavier structure necessary to withstand
the stresses of a carrier landing. The shape of the arresting hook is not compatible with low observable design, and that is why the fairing and doors
So I think that J-10 hook is similar to F-22 hook - just for emergency situations.
