    Default Error "; needed"

    So my code is just about finished for a project I have due tomorrow. However there's one part that's still preventing the code from being compiled completely. Here's the error it returns.

    Paniagua_ArrayProcessing.java:108: ';' expected
            public static void evenOdd(int[] array) throwsIOException{
                                                   ^
    1 error

    And here's the full code. I've looked it over for semicolons and brackets but nothing appears to be wrong. I don't know what I could or should do. Any help is appreciated. Thanks!

    import java.io.*;
    import java.util.Scanner;
    public class Paniagua_ArrayProcessing{
            //The main method: arranges all operations.
            public static void main(String[] args) throws IOException{
                    int[] numbers = inputData();
                    printArray(numbers);
                    reverseArray(numbers);
                    int arraySum = sum(numbers);
                    System.out.println("The sum of all elements is: " + arraySum);
                    double arrayMean = mean(numbers);
                    System.out.printf("The mean of all elements is: %.2f\n", arrayMean);
                    int arrayMin = min(numbers);

                    int arrayMax = max(numbers);
                    System.out.println("The max of all the elements is: " + arrayMax);

    You need a space space between throws and IOException.
