Why can't you call a non-static method from a static method within the same class?(Cannot make a static reference to the non-static field)

Question

In Java we can use

• non-static variables inside non-static methods without creating an instance within the same class.

• static variables inside non-static methods without having an issue within the same class.

• static variables inside a static a static method without having any issue within the same class.

I just want to know why we can not use a non static variable inside a static method within the same class.

Answer 1

It wouldn't make sense. Static methods are about belonging to the class, rather than individual instances. So, they don't have access to any instance (i.e. you can't use this™ inside them).

Things that aren't static are bound to individual instances.
