Java Programming: 14 – Constants



In this tutorial I explain how to make constants in Java by using the final modifier on variables.

By convention, constants are capitalized with words separated by underscores.

You usually want to make constants static because they typically do not change values across different instances. Using the static modifier also allows you to use the variable without creating any instances.

It is also generally safe to make your constants have public visibility, since applying the final modifier makes the variable read-only.
