Factorial Program in Java: Factorial of n is the product of all positive descending integers. Factorial of n is denoted by n!. For example: 4! = 4*3*2*1 = 24. 5! = 5*4*3*2*1 = 120. Here, 4! is pronounced as "4 factorial", it is also called "4 bang" or "4 shriek". The factorial is normally used in Combinations and Permutations (mathematics).
