    Default Figuring Out Object Arrays

    So I'm trying to figure out how to create Arrays out of Objects but I'm having a problem adding an Object to an Array.

    Here's what I have:
     
    public class Main {
     
           double[] values = new double[10];
     
        double[] morevalues = {2,3,4,5};
     
        double morevaluesone= morevalues[1];
     
        Coin Bank[] = new Coin[3];
     
     
        /**
         * @param args the command line arguments
         */
        public static void main(String[] args) {
     
    Coin quarter = new Coin("Quarter", .25);
     
    Bank[0]=quarter;

    I get the error at Bank[0]=quarter;

    (non-static variable Bank cannot be referenced from a static context)

    What am I doing wrong?

    Here is my coin class:
    public class Coin {
        String name;
        double value;
        public Coin (String aname, double avalue)
        {
            name=aname;
            value=avalue;
        }
     
     
     
    }

    Default Re: Figuring Out Object Arrays

    main is static, so any variables you access from this method must be static. See http://www.javaprogrammingforums.com...html#post18632

        double value;
        public Coin (String aname, double avalue)
        {
            name=aname;
            value=avalue;
        }
     
     
     
    }
    The non static variable “Bank” is trying to use in static method (main). To resolve the error you would require to modify “Bank” as static.
