Question

Is there a similar way to declare a with-statement in Java (as in Javascript), or are there structural reasons why this would not be possible?

---

For example, this Javascript:

with(obj)
{
  getHomeworkAverage();
  getTestAverage();
  getAttendance();
}

…is nice and easy. However, it would seem that method calls have to be chained to their object(s) every time in Java, with no such graceful shortcuts avaiable:

obj.getHomeworkAverage();
obj.getTestAverage();
obj.getAttendance();

This is very redundant, and especially irritating when there are many methods to call.

• So, is there any similar way to declare a with-statement in Java?
• And if this is not possible, what are the reasons that it is possible in Javascript as compared to not possible in Java?

Answer 1

If the class of obj is under your control, you could provide a Fluent interface, basically returning this in every function. This would let you chain method calls like this-

obj.getHomeworkAverage().getTestAverage().getAttendance();
