Completing a class definition

Question by user2086204

Suppose that you are given the following PetDriver class, which includes a main method:

public class PetDriver{
  public static void main(String[] args){
    int weight = 40;
    Pet doggie = new Pet("Rover", weight);
    System.out.println("my pet's name is " + doggie.getName());
    System.out.println("my pet's weight is " + doggie.getWeight());

Executing main produces the following output:

my pet’s name is Rover
my pet’s weight is 40

My code is as follows but It is returning null.

public class pet {

    public String name;
    public int weight = 40;

    public Pet (String y, int x){
        y = name;
        x = weight;

    public String getName(){
        return name;

    public int getWeight(){
        return weight;

Your constructor does not assign the value to the properties. Change them to the following.

public Pet (String y, int x){
  name = y;
  weight = x;
