Question

Consider the following class public abstract class Animal\{ public String name; public int age; public Animal(String name, int age) \{ this.name = name; this.age = age; \} public abstract String noise (); Write a concreate class called Cat that extends the Animal class. Cat objects will have two additional attributes called breed (a String) and isLongHaired (a boolean). The Cat class must have a single constructor that takes four inputs (name, age, breed, isLongHaired) and assigns them to their corresponding attributes properly. Be sure that you are not using attribute hiding. A Cat's noise is "moew" if the Cat is older then three years and "purr" otherwise. Do not worry about information hiding in this question.

Answer 1

To create a Cat class that extends the Animal class, define two additional attributes and a constructor. The Cat's noise should be "meow" if the age is over 3, and "purr" otherwise.

Step-by-step explanation:

To create a concrete Cat class that extends the Animal class, we need to define two additional attributes: breed (String) and isLongHaired (boolean), and a constructor that takes four inputs and assigns them to the corresponding attributes. Here's an example of how the Cat class can be implemented:

• 
  
• public class Cat extends Animal {
• 
  
• private String breed;
• 
  
• private boolean isLongHaired;
• 
  
• 
  
• public Cat(String name, int age, String breed, boolean isLongHaired) {
• 
  
• super(name, age);
• 
  
• this.breed = breed;
• 
  
• this.isLongHaired = isLongHaired;
• 
  
• }
• 
  
• 
  
• public String noise() {
• 
  
• if (age > 3) {
• 
  
• return "meow";
• 
  
• } else {
• 
  
• return "purr";
• 
  
• }
• 
  
• }
• 
  
• }
