Java 8 forEach
Share
The Java 8 forEach is an enhanced form of the standard for loop. It was first introduced in Java 5.
Java 8 provides the updated forEach() method with the ability to iterate the elements of a collection. The Iterable and Stream interface includes collection classes that extend the Iterable interface – the forEach loop can be used with such interfaces.
