Optionally getting field

Question

I have a class structure like this:

public class Foo {
    private FooB foob;

    public Optional getFoob() {
        return Optional.ofNullable         


        

Answer 1

Why you dont add a getValue methode to the class Foo? This would be a kind of delegation.

public class Foo {
   ...
   public Integer getValue() {
       if (foob == null) {
          return null;
       }
       return foob.getValA();
   }
}
