Question

This is the class I have to use:
/**
Class for basic pet data: name, age, and weight.
*/
public class Pet
{
private String name;
private int age; //in years
private double weight; //in pounds

public Pet () // default constructor
{
name = "No name yet.";
age = 0;
weight = 0;
}


public Pet (String initialName, int initialAge,
double initialWeight)
{
name = initialName;
if ((initialAge < 0) || (initialWeight < 0))
{
System.out.println ("Error: Negative age or weight.");
System.exit (0);
}
else
{
age = initialAge;
weight = initialWeight;
}
}


public void setPet (String newName, int newAge,
double newWeight)
{
name = newName;
if ((newAge < 0) || (newWeight < 0))
{
System.out.println ("Error: Negative age or weight.");
System.exit (0);
}
else
{
age = newAge;
weight = newWeight;
}
}


public Pet (String initialName)
{
name = initialName;
age = 0;
weight = 0;
}


public void setName (String newName)
{
name = newName; //age and weight are unchanged.
}


public Pet (int initialAge)
{
name = "No name yet.";
weight = 0;
if (initialAge < 0)
{
System.out.println ("Error: Negative age.");
System.exit (0);
}
else
age = initialAge;
}


public void setAge (int newAge)
{
if (newAge < 0)
{
System.out.println ("Error: Negative age.");
System.exit (0);
}
else
age = newAge;
//name and weight are unchanged.
}


public Pet (double initialWeight)
{
name = "No name yet";
age = 0;
if (initialWeight < 0)
{
System.out.println ("Error: Negative weight.");
System.exit (0);
}
else
weight = initialWeight;
}


public void setWeight (double newWeight)
{
if (newWeight < 0)
{
System.out.println ("Error: Negative weight.");
System.exit (0);
}
else
weight = newWeight; //name and age are unchanged.
}


public String getName ()
{
return name;
}


public int getAge ()
{
return age;
}


public double getWeight ()
{
return weight;
}


public void writeOutput ()
{
System.out.println ("Name: " + name);
System.out.println ("Age: " + age + " years");
System.out.println ("Weight: " + weight + " pounds");
}
}

And I have to write a program that reads the name, age, and weight of 5 pets and gives me back the max age, min age, max weight, min weight and average of both.

PLEASE PROVIDE FULL PROGRAM IN JAVA LANGUAGE FOR 5 STARS RATING
