import java.util.Scanner;
public class PetDemo
{
    public static void main (String [] args)
    {
        Pet yourPet = new Pet ("Jane Doe");
        System.out.println ("My records on your pet are inaccurate.");
        System.out.println ("Here is what they currently say:");
        yourPet.writeOutput ();
        Scanner keyboard = new Scanner (System.in);
        System.out.println ("Please enter the correct pet name:");
        String correctName = keyboard.nextLine ();
        yourPet.setName (correctName);
        System.out.println ("Please enter the correct pet age:");
        int correctAge = keyboard.nextInt ();
        yourPet.setAge (correctAge);
        System.out.println ("Please enter the correct pet weight:");
        double correctWeight = keyboard.nextDouble ();
        yourPet.setWeight (correctWeight);
        System.out.println ("My updated records now say:");
        yourPet.writeOutput ();
    }
}

Answer 1

//Pet.java
public class Pet {
  private String name;
  private int age;
  private double weight;

  public Pet(String name) {
    this.name = name;
  }

  public void setName(String name) {
    this.name = name;
  }

  public void setAge(int age) {
    this.age = age;
  }

  public void setWeight(double weight) {
    this.weight = weight;
  }

  public void writeOutput() {
    System.out.println("name='" + name + ", age=" + age + ", weight=" + weight);
  }
}
