Java Constants - Constant Variables using Keyword Final - Java Tutorial - Appficial

It is good practice to minimize the use of literal numbers, and to instead represent them using variables. If the value of the variable doesn’t change, such as the value of PI, then we can make it a constant variable using the keyword final:

final datatype VARIABLE_NAME = value;

Once a constant is initialized, it’s value cannot be changed.
By convention, constants are all upper case and words are separated by the underscore character
