Given the class Pet below, write a client program to read data for five pets and display the following data: name of smallest pet, name of largest pet, and average weight of the five pets. Make sure you explain and justify every line of your code using internal documentation to get full mark. /** Class for basic pet data: name, age, and weight. */ public class Pet { private String name; private int age; //in years private double weight;//in kg 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 Pet( ) { name = "No name yet."; age = 0; weight = 0; } 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 + " kg"); } }
