Do lung fish have both gills and lungs? How does this work?

Lungfish have external gills that act as lungs when the lungfish is out of the water. The gills work as gills in the water, and as long as they are kept moist, can bring in oxygen when on land. Some lung fish are even obligated to breath air often and not just stay in the water.
