Re: Sample Exam 2011

That we evaluated (+ 1 1) before and that the result is 2 is only known inside the application of that f function. we use the same (+ 1 1) again but its a new application of that function, so the scope is different, so we have to make an add operation again. at least thats how i understand it.

Re: Sample Exam 2011

Regarding Task 2.1 converting the function to scala is def flatten(l: List[Any]): List[Any] = { l.head match { case List() => List() case d: List[Any] => d.head :: flatten(d.tail :: l.tail) case d: Any => d :: flatten(l.tail) } } in my opinion using fold is then somehow like this def flattenF(l: Lis...

Doing the exercise tasks again - okay to press reset?

In order to learn for the exam, I want to do the homework tasks again. Can i press reset and do the tasks again or will the points i got for the tasks reset aswell then? Or did you save the points somewhere else, too, anyway?

Re: Ex 08 Task2

Ok if I understand that correctly, the small but important change in the UML is that after the refactoring we are dependant on interfaces and not concrete instances anymore and should show that in the diagram (I hope this is not too much of a giveaway of the solution, if it is correct).

Ex 08 Task2

I have a question regarding subtask b) from task 2. It says we should remove hardcoded dependencies and inject them through constructors. From looking at a code, I can see such a hardcoded dependency only in the DefaultEmailer. Afterwards, we should provide an UML-diagram which I don't understand be...

Re: Ex07 Task 3

If a costumer orders a pizza with additional toppings, how do I have to save this in the order? Should the toppings be connected with the ordered pizza (the pizza holds a list of toppings) or should the toppings be saved on their own? Visualized on the bill later: 1. Pizza A --additional toppings fo...

Re: Ex 06 Task 1

Ok, after looking through the pattern-slides, i know what the tasks actually wants us to do :) But i still have some questions: 1. "Only based on inheritance" - does this mean we also cannot use interfaces and implement them? Only "x extends y"? 2. Again on the "create expressions"-sentence. I still...

Ex 06 Task 1

I don't understand what to do in task 1, especially subtask 1. It says we should provide a design so that all operations are freely combinable. I assume with operations you mean "add", "mult" and possible future operations. The operations in the current design are freely combinable, you can put any ...

Re: ex05 task2

Another question regarding

public List<InHouseSearchResult> search(String... keywords) {
// for sake of simplicity a predefined search result is returned.
return emptyList();
}

In our new implementation, can we return emptyList() for simplicity aswell or do we have to implement more?

Re: Ex1 Task3

Another question regarding task 3: It says "For every edge candidate pixel, consider the grid direction (out of 4 directions) that is “most orthogonal" to the edge". Does this mean that we only have to care about all horizontal and vertical edges and can discard all other edge-vectors?
