Why A Non-static Variable Cannot Be Referenced From A Static Context?

Hey Kusum,
 

The non-static variable cannot be referenced from a static context is compiler error that occurs when the user tries to put program code to access a non-static variable inside main in Java that is static.

public class Static Test{
	Private int count=0;
	public static void main(String args[]) throws IOException{
		count++; //compiler error: non-static variable count cannot be referenced from a static context
	}
}
