Answer 1

You can use SnakeYaml

1. Add dep e.g snakeyaml

2. The Yaml class is the entry point for the API:

   Yaml yaml = new Yaml();

3. Now we’ll parse a YAML document with the Yaml class:

   Yaml yaml = new Yaml();
   InputStream inputStream = this.getClass()
                                 .getClassLoader()
                                 .getResourceAsStream("customer.yaml");
   Map<String, Object> obj = yaml.load(inputStream);          
   System.out.println(obj);
