JavaJavaJava Technologies Given a number of type integer, write a Java program to print its factorial. The factorial of a positive integer n is the product of all values from n to 1. For example, the factorial o
f(n) = f(n - 1) * n, if(n > 0) So, factorial of 5 is 120. But in different bases, the factorial may be different. For example, factorial of 5 in base 8 is 170. In this problem, you have to find the number of digit(s) of the factorial of an integer in a certain base...

Now the observent reader may note “gosh, it’s entirely possible the value will be longer than an integer”, so they’ll perhaps rewrite in terms of BigInteger or at least in terms oflong,depending on the requirements of the program. Thus: ...
