Java iterator implementation

I was a TA for a first-year Java programming course this year. Range can implement the Iterator without an inner class. An iterator is just an implementation of the java.

If you're using an existing iterable object (say, a LinkedList ) from . I have this simple MyArray class, with two simple methods:. Its very unusual to maintain an iterator as an instance variable of the class. If that is the case, the compiler can't automatically change an Instance to a T , because .

That completely depends on the object related to the Iterator. Remeber that (nearly) every Iterator is related to an Iterable which we iterate over . The use of type parameters (i.e. Java generics). Implementing an iterator over some collection, in this case an array.

Implementing the Iterable interface, . In implementing several kernel interfaces so far, you have. Iterator is an interface in the Java libraries (in the package java.util). This tutorial explains how to implement Java's Iterable interface,.

The point of using an iterator is to allow the the client to iterate over the collection of objects, without exposing implementation details.

To generate successive elements from a series, we can use java iterator. Java Iterator is a nice implementation of iterator design pattern .
