Keyword used to state that a value, class, or method can't be changed. If the final keyword is used to define a variable, the variable can't be changed within the program. When used to define a class, a final class cannot be subclassed. When used to define a function or method, a final method can't be overridden by subclasses.
This keyword is an essential part of Java programming and is not usually used with Processing. Consult a Java language reference or tutorial for more information.
final float constant = 12.84753; println(constant); // Prints "12.84753" to the console constant += 12.84; // ERROR! It's not possible to change a "final" value
