inheritance

Animal = Alliance
Dog = House
Cat = Army


When you convert to alliance, how do you know whether you need battle strength of house and army


Abstract class - gets the common methods between the two classes.
	Common stuff - getName, getYears, getBanner

	Cat and Dog both have sound() but have different implementation (dog has woof, cat has meow)

	Animal ani = new Cat()
	ani.sound() //

	Interfaces only have abstract methods // public abstract String sound();

Wrong: newArr[ii] = new Cat (arr[ii]);
Correct: arr[ii].clone(); 					Since we don't know the datatype
