Hi guys!
Right now I'm thinking about adding a private constructor to a class that only holds some String constants.
public class MyStrings {
// I want to add this:
private MyString() {}
public static final String ONE = "something";
public static final String TWO = "another";
...
}
Is there any performance or memory overhead if I add a private constructor to this class to prevent someone to instantiate it?
Do you think it's necessary at all or that private constructors for this purpose are a waste of time and code clutter?
