In the above code, we have to address the non-static variable with the object name. In a simple way, we have to create an object of the class to refer to a non-static variable from a static context. A new copy of all the non-static variables is created when a new instance of variable is created.How do you fix static reference to non-static method?
Static methods (also known as class methods) belong to the class itself and can be called without creating an instance of the class. To fix this error, you need to either make the method static or create an instance of the class and call the method on the instance.How do you reference a non-static method in Java?
i.e. referring a variable using static reference implies to referring using the class name. But, to access instance variables it is a must to create an object, these are not available in the memory, before instantiation. Therefore, you cannot make static reference to non-static fields(variables) in Java.- A static method cannot tell to which particular object the non-static member belongs to. Since there is no existing object, the non-static method doesn't belong to any object. Hence there is no way a non-static method can be referenced from static context.
