HF : method before name

[patrick van merchtn]

Hi, in my book Head First p. 62

You've got the creation of an object.

Dog dog1 = new Dog();
dog1.bark(); // the method
dog1.name = "Bart";
    

a few lines futher in this class you've got the method

public void bark(){
System.out.println(name + "hello");}    

My question is, it seems that he call first the method and later set a nanme. Is this ok in java, to add the name to the instance variable after you invoke the method where you need this name ?

sorry, I see it. Of course the first time when he invoke the method there is no name assigned to the variable and the result is :
null hello.
