title: How do you find the smallest value of an ArrayList?
body: <p>I have an array list called children that has objects that move around certain whole value distances in the GUI and I need to find the smallest of these values and print it to the console.</p>
  
  <p>I'm pretty sure this calls for a for loop right? I just don't know how to structure it correctly to make sure it looks at the values within the "children" <code>ArrayList</code>.
  Or is there some built in functionality within Eclipse to calculate the smallest value of an array list?</p>
