I want to be able to find the data immediately before an given piece of data. For example, say you had a list of names:
Bob, Tommy, Scott, Frank, Evan, Ryan, Jessy, Alex, Abner, Edward, Smith, Adam
A hypothetical method find() is passed a name, and returns the name immediately before it, sequentially.
For example, you run find(Ryan), which has a desired result of returning Evan. How would you accomplish this? Since there is no iterator, I am unsure how this would be done.
Here a simple snippet that would fix your issue
LinkedList<String> yourListWithName = new LinkedList<String>();
//Fill your list
ListIterator<String> listIterator = yourListWithName.listIterator();
String previous = null;
while(listIterator.hasNext()) {
if(listIterator.hasPrevious())
{
previous = listIterator.previous();
listIterator.next();
}
String current = listIterator.next();
if(current.equals(yourReceivedName))
//Your algorithm
}
