Given the below class:

public class Dog {

private String name;

private double weight;

private static int numDogs = 0;

public Dog(String name, double weight) {

this.name = name;

this.weight = weight;

numDogs++;

}

public String getName() {

return name;

}

public double getWeight() {

return weight;

}

public static int getNumDogs() {

return numDogs;

}

public static void increaseNumDogs() {

numDogs++;

}

public void printGreeting() {

System.out.println("Woof!");

}

@Override public String toString() {

return "Name: " + name + " Weight: " + weight;

}

}

1. Add a method call to getNumDogs to the below starter code:

public class DogTest {

public static void main(String[] args) {

Dog fluffy = new Dog("Fluffy", 10);

int num = //call getNumDogs method here!

}

}

1. Dog.getNumDogs();

2. Then, add a method call to the increaseNumDogs method.

3. Lastly, call the printGreeting method. What is different about the way you call this method compared to the prior two methods.
