modcount of the list lets you know if there has been a structural modification made that might cause the current operation to give incorrect results.

  List<String> arrNames = new ArrayList<String>();
  arrNames.add("Mugil");
  arrNames.add("Vinu");
  arrNames.add("Bala");
  arrNames.add("Madhu");		
  arrNames.remove(0);		
  arrNames.add("Swathi");		
  arrNames.remove(1);

When the control reaches
Line 6 The Size and Modcount of the arrNames would be 4
Line 7 The Size and Modcount would be 5 and size would be 3
Line 7 The Size and Modcount would be 6 and size would be 4

Fine the Screenshots below for further Details
