The code is implementing a Singleton pattern as it ensures that only one instance of the MyBuilder class is created and returned every time the builder object is accessed. The static variable 'builder' is initialized to null and only gets instantiated once when it's null, which happens when the method is called for the first time. Subsequent calls to the method return the same instance of the class.
