Language.Builder().getOh().getYes().getJava().getIsSoNice().setFor(() -> { return "DSLs";});

No trailing lambdas, no infix operators, no @DslMarkers, no top level functions, and an infinite list of examples of Java verbosity making even the smallest thing look like an ancient greek epic. Java is utterly terrible for DSLs.

   Language {
       oh {
           yes {
              Java {
                  isSoNice
           }
       }
   }
