Is there a programming language whose declarations are similar to those used in UML?

Question

Like:

  Employee: Person

       name: String
       id:   int


      + employeeCount(): int {
        ---------------
         return employeecount
      }
      + name():String {
           return name;
      }
      - secret():void {
           ///private method
      }

Answer 1

Objective C uses + for class methods and - for instance methods -- very different interpretation, but it's the only language I know that decorates methods with plus and minus signs like that;-).

The "name: type" notation (often enriched with a leading keyword such as var for variables and function for functions) was quite popular before C took over the world, most notably perhaps in Pascal (a now-somewhat-obscure language that had a credible bid of its own for world domination not all that long ago;-).
