Issue an overview

I’ve seen examples like this:

public class MaxSeconds {
   public static final int MAX_SECONDS = 25;
}
Copy the code

And suppose I can have a Constants class to wrap Constants and declare them static final.

I know almost nothing about Java and wonder if this is the best way to create constants.

This is perfectly acceptable, maybe even standard

(public/private) static final TYPE NAME = VALUE;
Copy the code

Where TYPE is the TYPE, NAME is the NAME of all uppercase letters with underlined Spaces, and VALUE is a constant VALUE.

I strongly recommend not putting constants in your own classes or interfaces.

Caveat: Variables declared final and mutable can still be changed; However, variables can never point to other objects. Such as:

public static final Point ORIGIN = new Point(0.0);

public static void main(String[] args){

    ORIGIN.x = 3;

}
Copy the code

That’s legal, so ORIGIN is going to be a point at 3 comma 0.
