However, for the purposes of comparison, Listing 5 illustrates the use of an iterator in conjunction with an ArrayList object. Iterator<Object[]> i = rowList.iterator(); while (i.hasNext()) { Object[] databaseRow1 = (Object[])i.next(); for (loop = 0; loop < dataItemsList.length;...
For HashMap, creative use is made of the threshold field to track the requested initial size until the bucket array is needed. On the read side the empty map case is tested with isEmpty(). On the write size a comparison of (table == EMPTY_TABLE) is used to detect the need to infla...
ThesynchronizedList()method is available injava.utilpackage. With the help ofsynchronizedList()method, we can make ArrayList synchronized. This is a static method, it is accessible with the class name too. (i.e. If we try to access with the class object, in that case, we will not get ...

The stop condition in our recursion logic islist.size() <=1. In other words,if thelistobject is empty or contains only a single element, we stop the recursion. In each recursion call, we execute “T value = list.remove(0)“, popping the first element from the list. It works in thi...
