    Default Need help with a code!

    public class Julpyssel{

    final int MIN = 0;

    final int MAX = 1;

    //deklarerar en int-array som kommer att innehålla antal timmar sömn per natt.
    int[] sleepPerNight = new int[30];

    int[] gamingPerWeek = new int[30];

    int[] studyPerWeek = new int[30];

    public void main(String[] args){

    Julpyssel stats = new Julpyssel();



    double[] average = new double [30];

    System.out.println("The group sleeps on average"+ average +" hours/night.");

    int maxHours = linearSearch(gamingPerWeek, MAX);

    System.out.println("The most devoted gamer played "+maxHours+" hours/day.");


    int median = stats.getMedian(gamingPerWeek);
    System.out.println("The median or gaming per week is "+median+".");

    double variance = stats.getVariance(studyPerWeek);
    System.out.println("The variance is "+variance+".");


    public void userInterface(){
    Julpyssel stats = new Julpyssel();

    boolean running = true;

    while (running == true){

    double average = stats.getAverage(sleepPerNight);




    //ska fylla arrayerna

    public static void fillArrays(){

    sleepPerNight[4] = 5;
    sleepPerNight[5] = 7;

    gamingPerWeek[10] = 1;
    gamingPerWeek[11] = 21;

    studyPerWeek[0] = 6;
    studyPerWeek[1] = 1;


    public int linearSearch(int[] input, int minMax){

    return 0;


    //Den ska returnera det värde som finns i mitten av listan.
    public static int getMedian(int[] input){

    return 0;

    } //Julpyssel

    double getVariance(int[] azad){

    return 0;



    --- Update ---

    I get the error, "cannot find symbol" in "double average = stats.getAverge"
    symbol: method getAverage(int[])
    location: variable stats of type Julpyssel

    It's difficult to help you with an inaccurate copy of the error message. Copy and paste it or type more carefully - the whole thing.

    Thats obvious, you dont have a method getAverage(int[] var) in your class. Please fix it. Even after that you will be having few more compilation error. Please review and fix them and good luck.
    Thanks and regards,
