Half the problem is that the BigDecimal class is kind of horrid in Java, and so is Map.Entry. The language lacks features that would make them more workable, like operator overloading, implicit constructors and destructuring/pattern matching. Now, the first two are very fair not to want in a language because they allow programmers to bring in an unlimited amount of user-defined complexity. Some destructuring however, would just make it easier to work with what's already in the language and libraries.
