This method may be called repeatedly to iterate through the list, or intermixed with calls to previous() to go back and forth. (Note that alternating calls to next and previous will return the same element repeatedly.) Specified by: next in interface Iterator<E> Returns: the next element ...
And of course, starting in Java 9, we can use the Stream API in conjunction with the Date API to iterate a stream of dates. As always, the code snippets can be foundover on GitHub. Get started with Spring 5 and Spring Boot 2, through theLearn Springcourse: ...
java.util.List servers = MBeanServerFactory.findMBeanServer(null); MBeanServer mbs = null; // Iterate through our list of MBeanServers and attempt to find the one we want. for (int i = 0; i < servers.size(); i++) { // Check if the MBean domain matches what we're looking ...

This example, taken from the StAX specification, shows how to instantiate an input factory, create a reader, and iterate over the elements of an XML stream: Using XMLEventReader TheXMLEventReaderAPI in the StAX event iterator API provides the means to map events in an XML stream to allocated...
