Given that we now have ways to iterate through collections, we can move on to an exercise that picks up where we left off: iterating through a list for data analysis. Exercise 2: Bringing Analytics into the AnalyzeInput Application We are going to start from where we left off at the end...
// support for iterating either positions and elements//--- nested PositionIterator class ---/*** A (nonstatic) inner class. Note well that each instance* contains an implicit reference to the containing list,* allowing us to call the list's methods directly.*/privateclassPositionIteratorimp...
Here's the standard idiom for iterating backward through a list. for (ListIterator<Type> it = list.listIterator(list.size()); it.hasPrevious(); ) { Type t = it.previous(); ... } Note the argument to listIterator in the preceding idiom. The List interface has two forms of the ...
Do not add or remove GXVAL objects to or from the IValList when iterating through the IValList. Tips Use count( ) in conjunction withgetNextKey( )andresetPosition( )to iterate through the IValList. Adding or deleting GXVAL objects changes the number of objects in a IValList. Be sure to...
Bubble Sort works by repeatedly iterating through the list of elements to be sorted. During each iteration, it compares adjacent elements and swaps them if they are not in a serial order. The largest element "bubbles" to the end of the list in the first pass, and subsequently, the next ...
Thus, iterating over the elements in a list is typically preferable to indexing through it if the caller does not know the implementation. The List interface provides a special iterator, called a ListIterator, that allows element insertion and replacement, and bidirectional access in addition to ...
At one point, I even worked on a "NodeListAdapater" adapter class that implementedIterable, which would have allowed for the following: for(Node childNode : new NodeListAdapter(node.getChildNodes())){ // Do something with childNode... ...

When filling a shape with a complex paint, Java 2D must query the Paint object every time it needs to assign a color to a pixel whereas a simple color fill only requires iterating through the pixels and assigning the same color to all of them. The graphics pipeline (from SDK 1.4) only...
This exception occurs when a collection is modified while iterating over it using methods other than those provided by the iterator object. For example, we have a list of hats and we want to remove all those that have ear flaps: List<IHat> hats =newArrayList<>(); hats.add(newUshanka()...
