Could you talk deeplier abt the performance and memory resources between static and instance methods?

Does static methods use up the application resources, which will not be released even if the instance of that class is released?

And is there any potential risk to static methods if their class will be used in a multi-threading environment?

In design wise, when should we use private static methods and when should not?

Let me try to make you clear about that.

with static method It would have one and only instance you will access same instance when you call the static method, So it solves the problem of memory consumption.

While with instance method method inside every object will have different values and that will be different for each object.

Though memory resources is less in static method but If you want different value for instance method then go for it only.

Hope this helps.
