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.

        int value = 12, factorial = 1, temp = value;
        while (temp > 0) {
            factorial *= temp;
        out.println("The factorial of " + value + " is " + factorial + ".");


The output of the program is given below:
