Fibonacci series

 Fibonacci series

Code:

import java.util.Scanner;

class Main{


    public static void main(String anyVar[]){
        Scanner sc=new Scanner(System.in);
        System.out.println("Enter any number till that yu want Fibonacci series:");
        int num=sc.nextInt();
        System.out.println("Fibonacci series till "+num+"is as follows:");
        int num1=1,num2=1,num3=0;
        for(int i=0;i<num;i++){
           if(i==0||i==1)
            System.out.print(1);
            else{
                //Fibonacci number is sum of previous two Fibonacci number
                num3=num1+num2;
                num1=num2;
                num2=num3;
                
                System.out.print(" "+num3);
            }
           
        }
   
 }


Output:

Enter any number till that yu want Fibonacci series:                                                                          

12                                                                                                                            

Fibonacci series till 12is as follows:                                                                                        

1 1 2 3 5 8 13 21 34 55 89 144

NVL

 NVL: The NVL function allows you to replace null values with a default value.  Simple explanation: if( first parameter's value==null ) then return second parameter value if( first parameter's value!=null) then return first parameter as is Example: nvl("xyz","")---->return xyz nvl(null,'xyz') ------------>return xyz
