a named constant is assigned a value that can not change during the running of the program

syntax used to declare a named constant: final datatype CONSTANTNAME

$$value;

for example: final double PI

;

in math, pi is known as a constant used to compute the area of a circle

go to page

$$of your textbook and read the program under Listing

$2$

predict how the program would run and what output would appear in the output window

open a new NetBeans project, using the same name as the book

$($

copy the code into your program

run the program; when the program asks for the radius, enter a number in the output window

then: add a command line on the line below your declaration of PI
