Convert Java Array to Iterable

Integer foo[] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 };

List<Integer> list = Arrays.asList(foo);
// or
Iterable<Integer> iterable = Arrays.asList(foo);

Though you need to use an Integer array (not an int array) for this to work.

For primitives, you can use guava:

Iterable<Integer> fooBar = Ints.asList(foo);

<dependency>
    <groupId>com.google.guava</groupId>
    <artifactId>guava</artifactId>
    <version>15.0</version>
    <type>jar</type>
</dependency>

For Java8 with lambdas: (Inspired by Jin Kwon’s answer)

final int[] arr = { 1, 2, 3 };
final Iterable<Integer> i1 = () -> Arrays.stream(arr).iterator();
final Iterable<Integer> i2 = () -> IntStream.of(arr).iterator();
final Iterable<Integer> i3 = () -> IntStream.of(arr).boxed().iterator();
