How to create constants in Java language
For the video, I am using the "vi" editor, but you can use any other editor. If you prefer, you can use an IDE (integrated development environment) such as Eclipse, NetBeans, IntelliJ IDEA ...
For the creation of constants:
Use the keyword "static" and "final" to create a constant
Each constant has a type (int, float, ...) associated
And follow the following recommendations.
Create all the constants of the application in a single separate file.
Use the capital letters to call the constants
If the name of the constant is composed, use the underscore to divide the words
Note that a constant is an immutable variable.
