how do i fix the illegal start of expression here

Question

How do I fix the illegal start of expression here, i don't see anything wrong with it though

static void divide(double a, double b){
            double c = (number_a / number_b);
            String s;
            if (c == Double.POSITIVE_INFINITY || c == Double.NEGATIVE_INFINITY || c == Double.NaN)
                s = "Undefined";
            else
                s = Double.toString(c);
            System.out.println(s);
        }

You can either check for `b == 0` or use [this](https://stackoverflow.com/questions/8311604/check-if-a-double-is-infinite-in-java) answer. — Trusky, Mar 29 '21 at 13:43
with an if statement, it's not as if you're not using those already. — Stultuske, Mar 29 '21 at 13:45
i'm new to java programming and i only copied that from one yt video lmao — anthony, Mar 29 '21 at 13:46
you don't learn anything by just copy pasting code. Read a textbook and try and write your own. — Stultuske, Mar 29 '21 at 13:48
You need to use a conditional statement - and you have 4 of those already in your code. Try to understand what those mean, and work out how to write your own that tests what you need. — Andy Turner, Mar 29 '21 at 13:49
im just trying to change infinity to undefined cuz yes I understood this code — anthony, Mar 29 '21 at 13:49
`double c = (number_a / number_b)` → `double c = (a / b)`. Note that the result can be `Infinity` even when `b` is non-zero. (ex. `1e200 / 1e-200`) — , Mar 30 '21 at 11:28

Try this.

static void divide(double a, double b) {
    double c = a / b;
    String s;
    if (Double.isInfinite(c) || Double.isNaN(c))
        s = "Undefined";
    else
        s = Double.toString(c);
    System.out.println(s);
}

it says illegal start of expression at static void divide(double a, double b) – anthony Mar 29 '21 at 14:21
