java arrays

Hello have what is probably a small problem, I have a java array class with this code in it:-

  int NUMBER_OF_YEARS = 5;
    String yearsWorked[] = {"First Year", "Five Years", "10 Years", "Fifteen Years", "Twenty Years"};
    double[] total_Wages = new double[NUMBER_OF_YEARS];
   
    /**
     * arrays class fills the array with the users input
     */
    public void Arrays() throws IOException
    {
        double sum = 0;
        for (int i = 1; (i <=NUMBER_OF_YEARS); i++)
        {
            System.out.println("Enter amount you expect to earn after "+yearsWorked[i-1]);
           
            //create an instance of the readline class
            UserInput wages_Earned = new UserInput();
            double wage =  wages_Earned.readDouble();
           
            sum+= wage;
            total_Wages[i-1] = wage;

what I want to do is refrence a specific location from another class I have tried using:-
arrayInput = arrayInput.total_Wages[4];
but this does not work any ideas much apreciated thanks.

what's the error?

I take it arrayInput is an instance of the Class which contains the above method?

you could make total_Wages data member public:

ie: public double[] total_Wages = ...


but the best practice is to create a getter:

public double[] getTotalWages() { return total_Wages; }


then you can do (assuming arrayInput is your class):

double[] totWages = arrayInput.getTotalWages();
myVal = totWages[4];

> arrayInput = arrayInput.total_Wages[4];

this line doesn't make any sense.


if arrayInput is the instance of your class, your are trying to assign total_Wages[4] (a double) to your instance which is of type Arrays.

if so, please accept a comment as answer so this can be moved to PAQ (previously asked questions)
