I am learning the FSM framework provided by AKKA using its JAVA API, so far I've come across examples using Lambda expressions that are supported with Java8 onwards. Is Java 8 a requirement? Can I use FSM with Java 7? If yes, are there any examples I can refer to?

From the documentation:
You cannot use Akka's FSM API, or any of the APIs in the current version of Akka, with Java 7. The last version of Akka that supported Java 7 was Akka 2.3, which reached its end of life in April 2017. Even in Akka 2.3, the Java variant of the FSM API used lambdas, which I think required the use of Java 8.
