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>
Code To Implement
DefaultImmutableList
class: | DefaultImmutableList.java | ![]() |
methods: | iterator | |
package: | immutable.list.assignment | |
source folder: | src/main/java |
iterator
public Iterator<E> iterator()
Example
class: | ListsExample.java | ![]() |
package: | immutable.list.example | |
source folder: | src/main/java |
The code:
ImmutableList<Integer> numbers = Lists.brackets(4, 66, 99); for (int i : numbers) { System.out.println(i); }
produces:
4 66 99
Test
class: | IterableAssignmentTestSuite.java | ![]() |
package: | immutable.list.assignment | |
source folder: | src/test/java |
