An INI file is an initialization or configuration file for Windows or MS-DOS.They have plain text content which comprises key-value pairs in sections. While we may prefer to configure our applications with Java’s native .properties files or other formats, we may sometimes need to consume data...
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...
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...

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; ...
one by one by calling next(). The method throws an exception when there are no more elements in the collection. In order to avoid the exception, you should call hasnext() before next(); this is to make sure the iterator advances only if the next element/object exist in the collection....
