<div class = "block">
<p>
Consider a program that can calculate the distance between cities. The
program should ask for the city names and calculate the results based
on the following table:
</p>

<table>
<tbody><tr>
  <th rowspan="6">f<br>r<br>o<br>m</th>

  <th colspan="5"><center>to</center></th>
</tr>

<tr>
  <th>&nbsp;</th>
  <th>0) Indianapolis</th>
  <th>1) New York</th>
  <th>2) Tokyo</th>

  <th>3) London</th>
</tr>

<tr>
  <th>0) Indianapolis</th>
  <td>0</td>
  <td>648</td>
  <td>6476</td>

  <td>4000</td>
</tr>

<tr>
  <th>1) New York</th>
  <td>648</td>
  <td>0</td>
  <td>6760</td>

  <td>3470</td>
</tr>

<tr>
  <th>2) Tokyo</th>
  <td>6476</td>
  <td>6760</td>
  <td>0</td>

  <td>5956</td>
</tr>

<tr>
  <th>3) London</th>
  <td>4000</td>
  <td>3470</td>
  <td>5956</td>

  <td>0</td>
</tr>

</tbody></table>

<p>
How would menus and arrays be used in such a program?
</p>

<p>
One possible solution is shown <a href = "DistanceCalc.java">here.</a>
The more important idea is the process.
