title: How to sort the first column in a 2-dimensional array based on the second?
body: <p>For example:</p>
  
  <p>My first column in the array is at first numerically in order. The Second column is numerically random. I want to place the second column in order, which of course will force the first column out of order. Any ideas how to do this in java. I have searched, but can't seem to find the vocabulary to properly find it.</p>
