#Java - More Exercise: Objects and Classes - 3. Car Salesman

Привет,

Може ли малко помощ. Дава ми 20 от 100.

Output-а, гледайки по единия нулев тест е същия, но има някакви интервали, които иска judge отпред. Не разбирам, изходите ми са същите, до толкова до колкото съвпадат с тези в документа.

Условие :

3.Car Salesman

Define two classes Car and Engine. A Car has a model, engine, weight and color. An Engine has model, power, displacement and efficiency. A Car’s weight and color and its Engine’s displacements and efficiency are optional.

On the first line, you will read a number N which will specify how many lines of engines you will receive, on each of the next N lines you will receive information about an Engine in the following format “<Model> <Power> <Displacement> <Efficiency>”. After the lines with engines, on the next line you will receive a number M – specifying the number of Cars that will follow, on each of the next M lines information about a Car will follow in the following format “<Model> <Engine> <Weight> <Color>”, where the engine in the format will be the model of an existing Engine. When creating the object for a Car, you should keep a reference to the real engine in it, instead of just the engine’s model, note that the optional properties might be missing from the formats.

Your task is to print each car (in the order you received them) and its information in the format defined bellow, if any of the optional fields has not been given print "n/a" in its place instead:

<CarModel>:
<EngineModel>:
Power: <EnginePower>
Displacement: <EngineDisplacement>
Efficiency: <EngineEfficiency>
Weight: <CarWeight>
Color: <CarColor>

Optional

Override the classes’s ToString() methods to have a reusable way of displaying the objects.

Ето решението ми.

:) Ще е супер и ако някой друг сподели код, моя не стана много окей, но пък работи.

p.s. -> @Override гърми с timeLimit, иначе работи в идето, но в Main класа го stream-нах, за да вземе 100/100.

Ето едно решение от мен, но имай предвид, че не взема 100/100 в Judge заради Time Limit на някои от тестовете.

Целта ми беше по-изчистено решение с regex и стриймове и някои основни валидации, което се надявам да ти е по-интересно и полезно.
