Java constructor and thread-safety 1. What a constructor call does mechanically Calling a constructor like new Foo(args) roughly does three things, in order, within the calling thread: Allocate memory for the object, with all fields set to their default values (0, false, null). Run field initializers, instance initializer blocks, and the constructor body, in textual order (superclass constructor first). Return a reference to the object.
