Can anyone help me with Java Course

Question

I can't seem to go past Java Practice 46.2

Answer 1

What is the task/question?
Can you copy what you've written into a codebit in the code playground and attach it here using the plus ➕️ button?

Answer 2

Why do you added the 2nd time main class inside cat class?
Remove those last line from
"public class program:
...
..
"
Just put a } brace.

Answer 3

This is the task
You love all animals, and have a dog and a cat as pets.
The program you are given defines an abstract class Animal, and has Dog & Cat classes inherited from it.
Implement the Swimmer and Player interface and override their methods swim() and play(), so that the given method calls output the following messages:
swim():
Dog => "Dog is swimming"
Cat => "Cat is swimming"
play():
Dog => "Dog is playing"
Cat => "Cat is playing"

Answer 4

class Main {
public static void main(String[] args) {

Animal dog = new Dog();
Animal cat = new Cat();

dog.swim();
dog.play();
cat.swim();
cat.play();
}
}

interface Swimmer{
void swim();
}

interface Player{
void play();
}

//implement the Swimmer and the Player interfaces
abstract class Animal implements Swimmer,Player{
}

class Dog extends Animal {
public void swim(){
System.out.println("Dog is swimming");
}
public void play(){
System.out.println("Dog is playing");
}
//Override the swim() and the play() methods

}
}

class Cat extends Animal {
public void swim(){
System.out.println("Cat is swimming");
}
public void play(){
System.out.println("Cat is playing");
}
public class Program:
public static void main(String[] args) {
Cat c = new Cat();
c.swim();
}
//Override the swim() and the play() methods

}
}
