Head First Java Book question

Greetings all!

I am totally new to Java, and am working through the "Head First" Java book, 2nd ed.

On p. 39 there's a class code example called GuessGame.

Right off the bat, the code looks like this:



My question is as follows.

There's another class called Player, which creates Player object instances.

the GuessGame class creates the Player Object by calling them via:

p1 = new Player();

Why did we need to put the Player p1 code lines at the top?

Couldn't the Guess game have called them by:

?

Thanks!

Player p1 is given to make p1 as an instance variable of the class
if you give this within a method this becomes a local variable whose scope is limited within
the method.
