Can a class be constant?
Class constants can be redefined by a child class. It’s possible to reference the class using a variable. The variable’s value can not be a keyword (e.g. self , parent and static ). Note that class constants are allocated once per class, and not for each class instance.
Which is the best way to describe the constant literals in a class?
The public|private static final TYPE NAME = VALUE; pattern is a good way of declaring a constant.
What is class constant in Java?

How to create a constant class in C #?
We are moving the constant variables into a separate class like below. A few of my team members suggested that we declare the class as sealed to avoid overriding option, and a few are suggesting that we mark it as static to avoid instance creation of the Constant class.
Which is the best way to create constants?
A few of my team members suggested that we declare the class as sealed to avoid overriding option, and a few are suggesting that we mark it as static to avoid instance creation of the Constant class. However, I prefer to have it as Sealed with a static constructor, since it will help us to initialize the read-only variables in future need.
Is there debate about the declaration of a Constants class?
There is a debate between my team members about the declaration of a Constants class. We are moving the constant variables into a separate class like below.
When do you add constants to a class in Java?
If the constants are strongly tied to an existing class or interface, you should add them to the class or interface. For example, all of the boxed numerical primitive classes, such as Integer and Double, export MIN_VALUE and MAX_VALUE constants.
