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.

and the other one behave as derieved class]

void print();
{
cout<<"this is base class"<<endl;
}};
class wateranimal
{
void display();
{
cout<<"this is another base class"<<endl:
}};
class animal:public landanimal,public wateranimal
{
void disp();
{
cout<<"this is derieved class"<<endl;
}};
void main()

@ 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?
