Need to add arrays to the below program. The program below works, but I'm not sure where to add arrays.
import java.util.Scanner;
/**

public class TaxApplication {
/**

*/
public static void main(String[] args) {
Scanner input = new Scanner(System.in); // to read the input
double wageSalTips;
double taxableInterest;
double unempCompPerFunds;
double adjustedIncome;
double taxableIncome;
double federalIncomeTax;
double EIC;
double totalPayments;
double tax;
double healthcare;
double totalTax;
double result;
int line5 = 10150;
System.out.println("Welcome to the 1040EZ Tax Form Application");
System.out.println("1 Wages, salaries, and tips. This should be shown in box 1 of your Form(s) W-2. Attach your Form(s) W-2.");
wageSalTips = input.nextDouble();
System.out.println("2 Taxable interest.");
taxableInterest = input.nextDouble();
System.out.println("3 Unemployment compensation and Alaska Permanent Fund dividends.");
unempCompPerFunds = input.nextDouble();
adjustedIncome = wageSalTips + taxableInterest + unempCompPerFunds;
System.out.println("4 Add lines 1, 2, and 3. This is your adjusted gross income. $" + adjustedIncome);
System.out.println("5 If no one can claim you (or your spouse if a joint return), enter $10,150 if single; $20,300 if married filing jointly. See back for explanation. " + line5);
taxableIncome = adjustedIncome - line5;
System.out.println("6 Subtract line 5 from line 4. If line 5 is larger than line 4, enter -0-. This is your taxable income. $" + taxableIncome);
System.out.println("7 Federal income tax withheld from Form(s) W-2 and 1040.");
federalIncomeTax = input.nextDouble();
System.out.println("8 Earned income credit (EIC)");
EIC = input.nextDouble();
totalPayments = federalIncomeTax + EIC;
System.out.println("9 Add lines 7 and 8. These are your total payments and credits. $" + totalPayments);
tax = taxableIncome * 0.15;
System.out.println("10 Tax. Multiply Line 6 by 0.15. $" + tax);
System.out.println("11 Health care: individual responsibility");
healthcare = input.nextDouble();
totalTax = tax + healthcare;
System.out.println("12 Add lines 10 and 11. This is your total tax. $" + Math.round(totalTax * 100.0) / 100.0);
result = totalPayments - totalTax;
System.out.println("13 Subtract line 12 from line 9. If result is positive, it is your refund. If result is negative, it is the amount you owe. $" + Math.round(result * 100.0) / 100.0);
}
