Answer / bhaskr reddy
interface LandAnimals {
class LandAnimal {
// define the Land Animal prperties
}
}
interface WaterAnimals{
class WaterAnimal{
// define the Water Animal prperties
}
}
Now define the "Animal" class by implementing the two
interfaces(WaterAnimals and LandAnimals ).
Note1 : Java supports defining the class inside an
interface.
Note 2 : In the previous answer somebody has defined two
seperate classes for WaterAnimal and Land animal
and his LandAnimal extends WaterAnimal then LandAnmal
becomes the Water animal this is poor object orientation.

@ Bhaskr Reddy
The only problem I see with your solution is when I want to create the object Animal which has to implement properties from both WaterAnimal and LandAnumal: How will I create an instance of of class Animal which implements both the interfaces at the same time?
