I need a UML class and sequnce diagram for the following code:

1. public abstract class Dog { protected String name; protected Dog (String name) { this.name = name; } public String getName() { return name; } public String speak() { return "Woof"; } public abstract int avgBreedWeight(); }

2. public class Labrador extends Dog { private String color; private int breedWeight = 75; public Labrador(String name, String color) { super(name); this.color = color; } public String speak() { return "WOOF"; } public int avgBreedWeight() { return breedWeight; } }

3. public class Yorkshire extends Dog { private String color; private int breedWeight =75; public Yorkshire(String name, String color) { super(name); this.color = color; } public String speak() { return "woof"; } public int avgBreedWeight() { return breedWeight; } }

4. public class DogTest { public static void main(String args[]) { Dog objLabrador = new Labrador("Franz","chocolate"); Dog objYorkshire = new Yorkshire ("Quatro","Black"); System.out.println(objLabrador.name + " says " + objLabrador.speak()); System.out.println("The average weight of a Labrador is " + objLabrador.avgBreedWeight()); System.out.println(objYorkshire.name + " says " + objYorkshire.speak()); System.out.println("The average weight of a Yorkshire is " + objYorkshire.avgBreedWeight()); } }
