# Features with backports
If we cannot immediately upgrade to Java 8, there are some ways to backport some Java 8 features to previous versions.



For each of the following features, here is the backport or similar library:
* **Lambdas:**  [Retrolambda](https://github.com/luontola/retrolambda)
* **Lazily Evaluated Sequences:**  [totallylazy](https://github.com/bodar/totallylazy)
* **Optional:**  [guava](https://github.com/google/guava)
* **Date/Time:**  [ThreeTen](https://www.threeten.org/)
* **Nashorn:**  [nashorn-backport](https://github.com/wro4j/nashorn-backport)

> Use the backports with caution.

Learn how to backport Java 8 features in case upgrading to Java 8 is not possible.
