## Java Program to find fibonnaci series up to a particular number – Q4

Q4: Java Program to find factorial of a given number without recursion

The Fibonacci numbers are the numbers in the following integer sequence, called the Fibonacci sequence, and characterized by the fact that every number after the first two is the sum of the two preceding ones.

For example:
0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, …

```class fibseries{
public static void main(String args[]){
int a = Integer.parseInt(args);
int f=0, f1=0, f2=1;
System.out.print("Fibbonacci Series: ");
for(int i=0; i<a; i++){
System.out.print(f1 + " ");
f = f1 + f2;
f1 = f2;
f2 = f;
}
}
}
```

## Java Program to find factorial of a given number with recursion – Q3

Q3: Java Program to find factorial of a given number with recursion

The factorial of a non-negative integer n, denoted by n!, is the product of all positive integers less than or equal to n.

For example:
5! =     5*4*3*2*1 = 120
6! = 6*5*4*3*2*1 = 720

```class fact_rec{
public static void main(String args[]){
int num;
long fac = 1;
num = Integer.parseInt(args);
fac = factorial(num);
System.out.println("Factorial of " + num + " is: " + fac);
}
public static long factorial(int num){
if(num<=1)
return 1;
else
return (num * factorial(num-1));
}
}
```
