Hello,

I am learning Java via Sybex OCA Book.

I have reached while loop description which has the following example on page 77:

int roomInBelly = 5; public void eatCheese(int bitesOfCheese) { while (bitesOfCheese > 0 && roomInBelly > 0) { bitesOfCheese--; roomInBelly--; } System.out.println(bitesOfCheese+" pieces of cheese left"); }

What confused me was that bitesOfCheese was never explicitly initialized, however still gets value of 5 assigned upon execution of eatCheese and therefore can legally participate in while expression check.
Could you please explain why does it automatically gets assigned the value of 5?

Thank you.
