static method vs object method which is better in such code sample.

Answer 1

"static method vs object method which is better" well it depends on the purpose of your usage.

If you want your method to be called up only after an instance of the class (containing that method) has been created, then you should define that method as non-static

And if you want to call your method without creating an instance of the class, then you should define your method as static

Answer 2

Object method is much better than static but it depend on method and requirements. i generally used static when it is not possible to create object before method call. and if your class has some instance variable then use object methods. you can't use class instance variables in static method.

object methods are specific to objects but static methods are not.

So if your method is not interfering with instance variables then you can make them static.
