IndexOutOfBoundException is thrown while adding values to ArrayList in Java

[Gurunathan5029]

Here I am trying to get the row values from database and adding it to the ArrayList. The values are getting added without any error but the exception is thrown at the end of the loop.

Code:
public ArrayList retrievelist(String database, String field, String table) {
Statement statement;
try {
statement = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_READ_ONLY);
String exten = ".dbo.";
String query = "select " + "" + field + "" + " from " + "[" + database + "]" + "" + exten + "" + "[" + table
+ "]";
ResultSet rs = statement.executeQuery(query);
ArrayList records = new ArrayList();
System.out.println("HIHIHI" + query);
while(rs.next())
{
System.out.println(rs.getString(field) + records.size());
records.add(rs.getString(field));
System.out.println(records.get(records.size()-1));
}
return records;

	} catch (Exception exception) {
		exception.printStackTrace();
	} 
	return null;
}

Output:
