Illustration of copy constructor

Todo:

+ finish the copy constructor so the new object has the same

shot records as the one it copies from.

+ add code to the main method to copy more Pet objects,

give each of them multiple "vacinate" calls, and display the objects

after each vacinate call.

*/

class Pet {

private String type;

private String name;

private String owner;

private String[] shots; //to hold vacination records

private int count; //shots count

public Pet(String type, String name, String owner){

this.type = type;

this.name = name;

this.owner = owner;

this.shots = new String[5];

this.count = 0;

}

//copy constructor

public Pet(Pet x){

this.name = x.name;

this.type = x.type;

this.owner = x.owner;

this.shots = new String[x.shots.length];

//copy all the shot records over

}

//vacinate a pet

public void vacinate(String desc){

//make sure no more shots than we can hold

if(this.count < this.shots.length)

this.shots[this.count++] = desc;

}

//change owner name

public void setOwner(String ownerName){

this.owner = ownerName;

}

//representing a pet object as a string

public String toString(){

String tmp = "";

for(int i = 0; i < this.count; i++)

tmp += this.shots[i] + " ";

return "Type: " + this.type + " " +

"Name: " + this.name + " " +

"Owner name: " + this.owner +

" Vacines: " + tmp;

}

}

/** testing the Pet class */

public class Feb3{

public static void main(String[] args){

Pet p = new Pet("Dog", "Yulu", "Ken");

p.vacinate("Flu");

System.out.println("P: " + p);

Pet p2 = new Pet(p);
