Create an array of Pet objects You want to keep track of all

Create an array of Pet objects. You want to keep track of all of your friends’ pets. Write a class called AllPets.java using PetRecord.java class as the array type. Allow the array to hold at least 4 records.

Ideally, we would read the pet data from a text file or allow the user to enter it from the keyboard, but to make writing & testing of your program easier, just hard code the pet details (name, age, & weight) into your main method.

After creating and setting the pet data, be sure to print all PetRecords to the screen to verify the contents of the array.

public class PetRecord1
{
private String name;
private int age;//in years

private int Smallest;
private int Largest;
private int Oldest;
private int Youngest;
private double AverageWeight;
private double AverageAge;

public void writeOutput( )
{
System.out.println(\"* Name: \" + name);

}

public PetRecord1(String initialName, int initialAge,
double initialWeight)
{

System.exit(0);
}
else
