Parsing Yaml in Java

I have the following YAML I want to parse using Jackson parser in Java.

android:
    "7.0":
        - nexus
        - S8
    "6.0":
        - s7
        - g5
ios:
    "10.0":
        - iphone 7
        - iphone 8

I created a created class which has getter and setter as Java Object for android. It works fine. But how do I do the same for 6.0 and 7.0? I'm usingJackson` Parser
