Instance variable is the variable declared inside a class, but outside a method: something like:
class IronMan { /** These are all instance variables **/ public String realName; public String[] superPowers; public int age; /** Getters and setters here **/ }
Now this IronMan Class can be instantiated in another class to use these variables. Something like:
class Avengers { public static void main(String[] a) { IronMan ironman = new IronMan(); ironman.realName = "Tony Stark"; // or ironman.setAge(30); } }
This is how we use the instance variables. Shameless plug: This example was pulled from this free e-book here here.
