# Page

Canonical page: https://docs.ovok.com/java-sdk/reference/page

```java
public final class Page<T> implements Iterable<T>
```

One page of results that can iterate through every later page.

Iterating loads the next pages on demand:

```java
for (JsonNode patient : ovok.slim().patients().list(Map.of(), RequestOptions.defaults())) {
    System.out.println(patient.path("id").asString());
}
```

**Type parameters:**

- `<T>`: the item type
