Question

QUESTION 5 In our flight booking sample, à Generic Flightâ is a: O Generic class o General Electric class Metaclass o General class Megaclass QUESTION 6 We can synchronize multiple activities by splitting the flow of control into different threads that we call... Side-scrollers Synchronization cells Chutes and ladders O Concurrency corners Swim lanes QUESTION 7 Which of these represent a good design? (Circle all correct answers) Low coherence Medium coupling and coherence High coherence High coupling Low coupling QUESTION 8 Which of the following naming conventions is correct? (Circle all correct answers) None of the above below Class name starts with lower case letter Conditions are enclosed with {curly brackets) Attribute starts with lower case letter Method starts with upper case letter

Answer 1

Answers 5. NO SAMPLE IS GIVEN HENCE USE BELOW EXPLAINATION OR GO WITH THIS ANSWER GENERIC CLASS

Explaination:- You can identify it if it is a generic method, you always let the caller decide, which type arguments to use for the type parameters. The implementation of the method must be able to deal with all possible types arguments (and it doesn’t even have a way to ask for the actual type arguments). Hence from my view it will be a generic class IF it dosenot have that caller decide,

ANSWER 6. swim lanes

Explaination:- they are used to parition / spilting of threads.

ANSWER 7:High Cohesion and low coupling

Explaination:-High Cohesion and low coupling give us better designed code that is easier to maintain.Coupling refers to the degree to which the different modules/classes depend on each other, it is suggested that all modules should be independent as far as possible, that's why low coupling.Cohesion refers to the degree to which the elements of a module/class belong together, it is suggested that the related code should be close to each other, so we should strive for high cohesion and bind all related code together as close as possible.

ANSWER 8: NONE OF THE BELOW

Explaination:- 1. class name can start with both lower and upper case, so only lower case is not correct.

2. condition can be used without curly braces we use if else with braces for a single line implemenation.

3. can be in both cases

4. can be in both cases
