Creating Dog Class In Java

Problem:

Design and implement a class called Dog that contains instance data that represents the dog’s name and age. Define the Dog constructor to accept and initialize instance data. Include getter and setter methods for the name and age. Include a method to compute and return the age of the dog in “person years” (seven times the dogs age). Include a toString method that returns a one-line description of the dog. Create a driver class called Kennel, whose main method instantiates and updates several Dog objects.

Solution:

public class Dog
{
 private int age;
 private String name; 
 public Dog(int age,String name)
 {
  this.age = age;
  this.name = name;
 }
 
 public String setDogName(String name)
 {
  this.name = name;
  return name;
 }
 
 public int getDogName()
 {
  return age;
 }
 
 public int setDogAge(int age)
 {
  this.age = age;
  return age;
 }
 
 public int getDogAge()
 {
  return age;
 }
 
 public int computeDogAge()
 {
  this.age = age*7;
  return age;
 }
 
 public String toString()
 {
  String dogsname= "Dog's name: ";
  String dogsage= "Dog's age: ";
  return dogsname + name + "\t" + 
                  dogsage +  age ;
 } 
 
 public static void main (String[] args)
 {
  Dog dog1 = new Dog(1,"Lucky");
  Dog dog2 = new Dog(2,"Starc");
  Dog dog3 = new Dog(5,"Lutchy");
  
  dog1.setDogAge(9);
  System.out.println(dog1);
  
  dog2.setDogName("Azzam");
  System.out.println(dog2);
  
  System.out.println(dog3);
  
  System.out.println();
  System.out.println("Dog's ages in person 
                       + years:");
  System.out.println(dog1.computeDogAge());
  System.out.println(dog2.computeDogAge());
  System.out.println(dog3.computeDogAge());
 }
}
