Help me to understand the last line of this program
System.out.println(Animal.numAnimal);
And also it print output 3 how?

Answer 1

You have a static variable numAnimal in the Animal class and the following constructor:

Animal(){
numAnimal++;
}

Each time an object of type Animal is instantiated, numAnimal is incremented by 1. Based on the code, 3 objects of type Animal are created (cat and dog both of which are child classes of Animal and an Animal object). Thus, you get 3 when you print out the numAnimal variable.

Check this out to understand the static variable:

Based on your profile, you haven't finished the Java tutorial yet. I suggest you review some of its topics if you are still having issues. The comments section in the lesson are a big help. Good luck and happy coding!

Answer 2

Lines 41, 43 and 46. Note the use of the keyword "new" which is the syntax used to create an object.
