• Recall:
  • Conformal arrays make it possible to work with "records" consisting of multiple "fields"
• An Inconvenience:
  • All of the arrays must be passed to methods that need them

• Use an Array of "struct" Objects:
  • Create a class that holds the values "side-by-side" (which needn't have methods and might even have public attributes for convenience)
  • Create an array of these objects
• About the Name:
  • Some languages (e.g., C) have this capability
  • A struct is a collection of heterogeneous elements (unlike an array which is a collection of homogeneous values)

public class Sales
{
    public double amount;
    public String code;
}

double     mean, total;
Sales[]    sales;
int        month;

sales = new Sales[12];

month = 0;
while (month < 12) 
{
  JMUConsole.printf("Enter the 3-letter code for %d: ", month);
  sales[month].code  = JMUConsole.readLine();

  System.out.printf("Enter the sales for %s: ", code[month]);
  sales[month].amount = JMUConsole.readDouble();

  month++;
}
