// Iterator - Returns an iterator over the elements in this list in proper sequence. System.out.println("\n===> 3. Iterator Example..."); Iterator<String>crunchifyIterator = crunchifyList.iterator(); while(crunchifyIterator.hasNext()){ System.out.println(crunchifyIterator.next()); } //...
which looks for a value that equals three and deletes it. But the iterator is already in progress, and the attempt to delete the 3 will fail, and this
Since Java 5,java.uti.concurrentpackage has lots of useful but complex classes to work on concurrent applications.CountDownLatchis one of those classes which are highly asked in any Java interview with big corporates. In this tutorial,CountDownLatchis explained with examples and concepts around it...
In this program, we have illustrated the use of iterator method for iterating over a map. We have created a map and then defined an iterator method that will be used to iterate over the elements of the map. The methoditorator.hasnextis used to check if the next element of the iterator...

We can then use theIteratorthat provides all the keys for the section and usegetProperty()with each to get the key-value pairs. While aMapis harder to produce here, the advantage of the plainer data structure is that we can hide the INI file parsing from other parts of the system. Or,...
Keep in mind that this will give you the desired result, but you will also lose the laziness of a Stream because you need to consume it before inserting a new element. The alternative is to use Spliterator and iterate the elements sequentially to the target index (using the iterator of ...
