Is it possible to access non static variable inside the static block, and how?

if we pas the object of  the class in the static block the we access the non static variable  in the static block

Actually, It's not possible to access a non-static variable inside a static block.

Static variable is a class variable; you can access it through the name of class without creating an object from that class.

Example: MyClass.myVariable = 5;

Moreover, you can access it through the reference of the object of that class

Example: myRef.myVariable = 5;

They're strictly the same.
