goals is an array

and it iterates over the elements

that condition checks to see if the element at index 1 less than p is equal to 0. if so it prints "previous game had no goals" to the console

this code should throw an IndexOutOfBoundsException though

when p = 0, p - 1 = -1 and -1 is an invalid index

because you need the index of to access an element in an array

for loops are meant to simplify the process (In java terms)

you could write ```
int i = 0;
while (i < arr.length) {
//blabla
i++
}

// or

for (int i = 0; i < arr.length; i++) {
//blabla
}

I personally like the latter.

because it should be System.out.println

it probably is in other langs

in Java for loops almost have a single purpose

I mean that's a bit of an overstatement. but when you see a for loop you know what's happening. they are used far more often than while loops in terms of general iteration
