Task

Fill in parseOrDefault so that it returns the number in the string, or def when the string is not a number.

The program prints 42 and then -1.

Your solution

public class Main {

    public static int parseOrDefault(String s, int def) {
        // parse or default

    }

    public static void main(String[] args) {
        System.out.println(parseOrDefault("42", -1));
        System.out.println(parseOrDefault("abc", -1));
    }
}
