Iterable Immutable List Assignment
Contents
Studio To Revisit
In this studio we will complete the DefaultImmutableList
implementation from the ImmutableList studio.
ImmutableList
The ImmutableList interface extends Iterable which has one method: iterator().
public interface ImmutableList<E> extends Iterable<E> { E head(); ImmutableList<E> tail(); boolean isEmpty(); }
Iterable
interface java.lang.Iterable<T>
Iterator
interface java.util.Iterator<T>

Example
class: | IterableImmutableListExample.java | ![]() |
package: | immutable.list.example | |
source folder: | src/main/java |
The code:
ImmutableList<Integer> numbers = Lists.brackets(4, 66, 99); for (Integer i : numbers) { System.out.println(i); }
produces:
4 66 99
