As we saw in the previous examples, it’s very verbose to use anIteratorwhen we just want to go over all the elements and do something with them. Since Java 8, we have theforEachRemainingmethod that allows the use of lambdas to processing remaining elements: iter.forEachRemaining(System.o...

In this tutorial, we will learn about the Java Iterator interface with the help of an example. All the Java collections include an iterator() method. This method returns an instance of iterator used to iterate over elements of collections.
In the case of the collection being large in size, using the.stream()and the.parallelStream()from theStream APIis the best practice, as the Streams are lazily operated. Although Stream internally uses theSpliteratoronly. big.stream().forEach(System.out::println); ...
