    Default Help With errors. Please.

    I need help compiling my code in Java. I have a couple errors. Thanks for the help.



    My code:

     
        31  public class WeekTemp {
        32
        33  public static void main(String[] args) {
        34  char[] ref = createArray();
        35
        36
        37
        38  System.out.println("Enter a integer between 1 and 52 to indicate the week of the year: ");
        39  displayArray(ref);
        40
        41  int[] counts = countLetters(chars);
        42
        43  System.out.println();
        44  System.out.println("The 10 reference values for the week are: ");
        45  displayCounts(counts);
        46
        47
        48  public static char[] createArray() {
        49  
        50  char[] ref = new char[52];
        51  
        52  for (int i = 0; i < chars.length; i++)
        53  chars[i] = Random
        54  
        55  public class WeekTemp {

    Well, what are you trying to do in the first place? It'd be a lot more helpful if we knew the reason behind what the code actually does.
    EDIT: And well, line 53 just sets each element to "Random", I'm not sure if that got cut off while pasting, but, that definitely doesn't make sense.

    The arrays obs[] and ref[] are each 10 elements long, with obs[] representing the 10 different readings taken on a given day in the plant. Now, the values of the 10 elements in obs[] change every day of the five-day week but for a given week, the ref[] values are the same. These can be thought of fixed values to be adhered to for a whole week, but the fixed values are different for different weeks. The goal is to find the total deviation for a given week.
