## Factorial Program in Java:

Factorial of a number means the product of all positive descending integers.
for example: If we want to calculate factorial of 5 then it will be written as
5 x 4 x 3 x 2 x 1 = 120 . So 120 is the factorial of  5.

## Fibonacci Series In Java:

The fibonacci series is a series where the next number is the sum of previous two numbers.
for examples:  0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55 etc

above you can see first two numbers of fibonacci series are 0 and 1.
