body: <p>What is the best way to store table like data like: </p>
  
  <pre><code>         | Column 0 | Column 1 | Column 2 | Column 3 | Column 4
  Row 0    | 0.984546 | 0.654564 | 0.467676 | 0.673466 | 50.03333
  Row 1    | 0.684546 | 0.457564 | 0.467776 | 0.674566 | 45.73335
  Row 2    | 0.884546 | 0.424564 | 0.445676 | 0.664566 | 12.23333
  Row 3    | 0.284546 | 0.054564 | 0.237676 | 0.124566 | 45.01333
  </code></pre>
  
  <p>Both max column and row is dynamic and the coordinates of the value is very important, as I have to do calculation based on those value. It's not a database because the data is different every time and I don't want it to be forever there. Also, I need it to be easily accessible. I try to use <code>LinkedList</code> with <code>Double[]</code> but it's just too difficult for me to locate each of the value. Speed is a factor too.</p>
  
  <p>Any suggestion on the type of collection I should use or ways to handle it?</p>
