Question

What is wrong with this Code? Fix the code errors to run correctly without error. There are seven parts for one code, all are small code segments for one question. All the 'pets' need to 'speak', every sheet of code is connected. Four do need need any Debugging, three do have problems that need to be fixed.

Does not need Debugging:

public class Bird extends Pet {

public Bird(String name)
{
super(name);
}

public void saySomething(){}

}

public class Cat extends Pet {
  
public Cat(String name)
{
super(name);
}

@Override
public void saySomething()
{
System.out.println("Meow.");
}

@Override
public String toString()
{
return "Hello, I'm " + name + " the cat.";
}
}

public class Dog extends Pet {

public Dog (String name)
{
super(name);
}

@Override
public void saySomething()
{
System.out.println("Ruff, ruff!");
}

@Override
public String toString()
{
return "Hello, I'm " + name + " the dog.";
}
}

public class Parrot extends Bird {

public Parrot (String name)
{
super(name);
}

@Override
public void saySomething()
{
System.out.println("Pauly want a craker?");
}

@Override
public String toString()
{
return "Hello, I'm " + name + " the parrot.";
}

}

Needs to be Fixed:

public abstract class Pet {

String name;

public Pet(String name){
this.name = name;
}
}

import java.util.ArrayList;

public class PetTest {

public static void main(String[] args)
{
ArrayList<Pet> myPets = new ArrayList<Pet>();
  
myPets.add(new Parrot("Boss"));
myPets.add(new Cat("Oreo"));
myPets.add(new Dog("Riley"));
  
for (Pet p: myPets)
{
p.saySomething();
System.out.println(p);
}
}
}

public class Speak {
public void saySomething();
}

Please find the complete code below>>

Pet.java

package classes16;

public abstract class Pet {

   String name;

   public Pet(String name){
       this.name = name;
   }
  
   public abstract void saySomething();
}

Bird.java

package classes16;

public class Bird extends Pet {

public Bird(String name)
{
super(name);
}

public void saySomething(){}

}

Cat.java

package classes16;

public class Cat extends Pet {

   public Cat(String name)
   {
       super(name);
   }

   @Override
   public void saySomething()
   {
       System.out.println("Meow.");
   }

   @Override
   public String toString()
   {
       return "Hello, I'm " + name + " the cat.";
   }
}

Dog.java

package classes16;

public class Dog extends Pet {

   public Dog (String name)
   {
       super(name);
   }

   @Override
   public void saySomething()
   {
       System.out.println("Ruff, ruff!");
   }

   @Override
   public String toString()
   {
       return "Hello, I'm " + name + " the dog.";
   }
}

Parrot.java

package classes16;

public class Parrot extends Bird {

public Parrot (String name)
{
super(name);
}

@Override
public void saySomething()
{
System.out.println("Pauly want a craker?");
}

@Override
public String toString()
{
return "Hello, I'm " + name + " the parrot.";
}

}

PetTest.java

package classes16;
import java.util.ArrayList;

public class PetTest {
   public static void main(String[] args)
   {
       ArrayList<Pet> myPets = new ArrayList<Pet>();

       myPets.add(new Parrot("Boss"));
       myPets.add(new Cat("Oreo"));
       myPets.add(new Dog("Riley"));

       for (Pet p: myPets)
       {
           p.saySomething();
           System.out.println(p);
       }
   }
}

output:
