Inner class code example

[Mansukhdeep Thind]

Hi

I tried out the following code :

public class Navel {
	private int size =7;
	private static int length = 3;
	public static void main(String[] args){
		new Navel().go();
	}
	
	void go(){
		int size = 5;
		System.out.println(new Gazer().adder());
	}
	
	class Gazer{
		int adder() {return size * length;}
	}
}

The result is 21. My question is how can class Gazer access a static variable? I mean we are trying to access a static member of the outer class from a non static context. So it should throw an exception right?

There's never anything wrong with accessing a static member from a non-static context.

Ohhh.. Ok.. So the problem is when we try to access a non static member from a static context. Correct Paul? That will upset the compiler right?

Yes, I'm sure you must have seen that message already, haven't you?

Thank you Paul.
