Answer 1

A method is nothing but a set of instructions. Whichever thread calls the method, get a copy of those instructions. After that the execution begins. The method may use local variables which are method and thread-scoped, or it may use shared resources, like static resources, shared objects or other resources, which are visible across threads.
