Finding a Factorial using while loop
In this example we are going to find out the factorial
of 12 by using the while loop. In while loop the loop will run until the
condition we have given gets true. We are using the scriptlet to
calculate the factorial of 12. In the scriptlet we generally writes a java logic
in it. The output will be displayed by using the out implicit object used
to write the content on the browser.
We can find a factorial of a number by using the temp
variable which will help us to calculate the factorial of a number. Take one
variable factorial of int type and initialize it as 1. Take another
variable value of type int of which you want to calculate the factorial
.Now use while loop and pass the condition that until temp> 0, the loop
should perform the following task: the factorial = factorial* temp and
keep on decreasing the value of temp by l.
