Answer 1

public class AverageStringsLength {

    public static double averageStringLength(String[] strings) {
        double total = 0;
        for (int i = 0; i < strings.length; i++) {
            total += strings[i].length();
        }
        return total/strings.length;
    }

    public static void main(String[] args) {
        String[] arr = {"Hello", "hi", "How", "are", "YOU?"};
        System.out.println("Average word length is " + averageStringLength(arr));
    }
}
