Frogs and toads have gills as tadpoles, and lungs as adults.
When an amphibian is a larva, it will have gills. As it matures into the adult stage, it will develop lungs.
A amphibian has neither lungs or gills
Amphibian lungs do not have to be as efficient as gills because there is much more oxygen in air than in water.
Most amphibians grow out of their gills before adulthood.

A vertebrate that begins its life breathing water and grows up to breathe air as an adult is an amphibian. Amphibians, such as frogs and salamanders, typically start their life cycle as aquatic larvae with gills for breathing underwater. As they mature, they undergo metamorphosis, developing lungs to breathe air as adults. This dual life cycle is a defining characteristic of amphibians.
They grow lungs, and lose their gills.
Amphibians, such as frogs and salamanders, begin life with gills for underwater breathing and later develop lungs to breathe on land as they mature. This transition from gills to lungs is part of their metamorphosis process.
In the early stages of development, amphibians live in the water they breathe with gills as an adult an amphibian lives on land and uses lungs to breathe.
Amphibians are tricky. Some - like frogs and toads - start out using gills when they're tadpoles and switch over to lungs as they mature. There's a salamander that has the option to choose depending on water level whether to keep the gills or to develop lungs as it matures. Some are so good at absorbing oxygen through their skin that they can stay submerged indefinitely even without gills.
