A public static final variable is a compile-time constant, but a public final is just a final variable, i.e. you cannot reassign value to it but it’s not a compile-time constant. This may look puzzling, but the actual difference allows how the compiler treats those two variables.

What is a public static final String?

A public static final variable is a compile-time constant, but a public final is just a final variable, i.e. you cannot reassign value to it but it’s not a compile-time constant. This may look puzzling, but the actual difference allows how the compiler treats those two variables.

Should static final variables be public?

Static variables are created when the program starts and destroyed when the program stops. Visibility is similar to instance variables. However, most static variables are declared public since they must be available for users of the class.
