Course Introduction:1.

Course Introduction:Iterator and Iterable are important components in the Java collection framework for implementing collection traversal. Iterator is an interface that provides a traversal mechanism for the elements in a collection, allowing each element to be accessed sequentially. Iterable is an interface that defines the traversal capabilities of a collection, allowing the use of foreach syntax to traverse the elements in the collection. The main difference between Iterator and Iterable is that: Iterator is an interface used to represent the traversal of elements in a collection; Iterable is an interface used to represent the traversability of a collection. Iterator provides hasNext() and next() methods to traverse the elements in the collection
