I have a program that i have to convert to using arrays instead of what i have to do the same thing and i'm not the strongest with array can any one help?

... i had hoped to just attach this but it is too big so unfortunutly i have to just post it

import java.io.*;
import java.util.*;
import java.text.*;

public class program7

DecimalFormat fmt = new DecimalFormat ("0.00");

outfile.println("Output File");
header (outfile);
int n = infile.nextInt();
for ( int i = 1; i <= n; i++)
{ miles = infile.nextDouble();

if (miles < 500)
amount = .15*miles;
else if (miles < 1000)

outfile.println(leftpad1(miles,10) + " " + leftpad2(amount,15));
