In this example, we’ve created aLinkedListof integers and added several elements to it. We then used the foreachloopto iterate through its elements. The foreach loop automatically calls theiteratormethod on thelinkedListobject to obtain an Iterator, and then repeatedly calls thehasNextandnextmetho...
The hasNext() method checks if there are more elements, and next() retrieves the next element in the iteration. Let’s consider an example where we have a list of Double values, and we want to print each value using an Iterator. import java.util.ArrayList; import java.util.Iterator; ...
Java ArrayList.listIterator() returns a bi-directional list iterator that iterates over the elements of the current list.

Now we can use Guava’sSplitterclass to truncate ourString: staticStringusingSplitter(String text,intlength){ Iterable<String> parts = Splitter.fixedLength(length) .split(text);returnparts.iterator() .next(); }Copy We usedSplitter.fixedLength()to split ourStringinto multiple pieces of the given...
