Q.  How do I sort an ArrayList?

A.

	ArrayList<MyEntry> 	a;

	// Add things to array a

	Collections.sort(a, new customCompare);

Where customCompare is:

	public class customCompare implements java.util.Comparator<Entry> {
		public int compare(MyEntry a, MyEnry b) {
			return a.field1.compareTo(b.field1);
		}
	}
