Question

Using Java

Write a class called Dog that contains instance data that represents the dog’s name, breed, weight, birth date, and medical history. Define the Dog constructor to accept and initialize instance data (begin the medical history with an empty line). Include accessor and mutator methods every attribute. For the medical history in particular, define the mutator method to simply add strings to the medical history so the user sees a printout of information about the dog (be mindful of adding new line characters). Include a toString method that returns the dog's information in a "nice" format (this is subjective, up to you how you do it). Create a driver class called Vet, whose main method instantiates and updates several Dog objects.

class Dog{
String name,breed,birth_date,medical_history="\n";
int weight;
public Dog(String n,String b,String d,String m,int w){//constructor of class
this.name=n;
this.breed=b;
this.birth_date=d;
this.weight=w;
this.medical_history+=("\n"+m);//new line character is used here for medical_history
}
public String getName(){
return this.name;
}
public String getBreed(){//getter and setter methods
return this.breed;
}
public String getBirthDate(){
return this.birth_date;
}
public String getMedicalHistory(){
return this.medical_history;
}
public int getWeight(){
return this.weight;
}
public void setName(String n){
this.name=n;
}
public void getBreed(String d){
this.breed=d;
}
public void getBirthDate(String d){
this.birth_date=d;
}
public void getMedicalHistory(String m){
this.medical_history+=("\n"+m);
}
public void setWeight(int w){
this.weight=w;
}
public String toString(){//string representation of Dog class
return "Name is: "+this.name+" Breed is: "+this.breed+" birth date is: "+this.birth_date+" Weight is: "+this.weight+" Medical History: "+this.medical_history;
}
}
public class Vet
{
   public static void main(String[] args) {
       Dog d1=new Dog("name1","breed1","date1","Healthy",20);//create a dog object and print it
       System.out.println(d1);
       d1.setName("Pinky");//update the name of dog and print the dog details
       System.out.println(d1);
   }
}

See that name of the dog is changed to pinky here.
