Which of the following statements is false?
Sergio039 [100]

Answer:

Option (d)

Explanation:

Option (a) the return type of the method specifies the type of the data that is returned for the method calling. The return type can be void if it doesn't return any value. The method return can be int, string and bool etc. So, option (a) is true and it not the correct option.

Option (b) is true it doesn't need any parameters. So, option (b) is not the correct option.

Option (c) is true. If the method has some return type other than void it must return something according to the return type.So, option (c) is not the correct option.

Option (d) is false. Getters and setters methods are used for accessing private variables but the name MUST start with get or set is false. The best practice is to start with get and set but it is NOT a must.

So, option (d) is correct option.
