circular list?

[ronparker]

Hello!
I have a private arraylist with classes that include two longs, a float and a BigDecimal. As new data comes in I currently am removing the oldest element, shifiting all other elements over, and then adding the newest element. I think this is taking up a lot of memory uncessearly. So is there anyway to make this a circle, so I don't need to shift over elements in the array? Thank you in advance for any help on this!
I'll include the relevenat parts of my code below:

private ArrayList<privStat> MyList = new ArrayList<privStat>();
public class privStat {
   long Stat1;
   long Stat2;
   float Stat3;
   BigDecimal Stat4;
}

NewStat = new privStat(//new message)
if (MyList.size() - 1 < 10) {
   MyList.add(NewStat);
} else {
    Mylist.remove(0);
    Mylist.add(NewStat);
}

Any help on this Linked list??

private LinkedList<privStat> MyList = new LinkedList<privStat>();
public class privStat {
   long Stat1;
   long Stat2;
   float Stat3;
   BigDecimal Stat4;
}

NewStat = new privStat(//new message)
if (MyList.size() - 1 < 10) {
   MyList.add(NewStat);
} else {
    Mylist.remove(0);
    Mylist.add(NewStat);
}
