Question

if(MISSING CONDITION){

return true;

} else {

return false;

}

}

B. num % 0 == 2;

D. num % 1 == 2;

Answer 1

Answer:

The answer is "Choice A".

Explanation:

In this code, a method "isEven" is declared that accepts the "num" variable in its parameter, and inside the method and if block is declared that checks the even number condition if it is true it will return a value that is "true" otherwise it will go to else block that will return "false" value, that's why other choices are wrong.
