JNTU Hyderabad CSE/IT Java OOPS Week 1B - To find the numbers of Fibonacci series

Are you looking for JNTU Hyderabad CSE/IT solved java 2-2 lab assignments and week programs ? Here is the perfect resource for you . You can directly copy and paste the below code in a Java Editor to excecute the program.

Get the solutions for JNTU Btech Lab java programs for CSE and Information Technology branches . The resource includes the clear explanation of the code. The below code was uploaded only after the successful execution using Java Standard Edition. JNTU Hyderabad and affiliated colleges conducts a lab session every week for all B.tech Regular students. Here I'm giving solution for the Week 1 2nd program. The aim of the program is to generate the fibonacci series using a simple java program .You can also get more information about JNTU Java programs solutions on this site for all weeks.
Input: The value of n is given as input.
Fibonacci series:
0,1,1,2,3,5,8,13,21,34...
where f(0)=0,f(1)=1,f(n)=f(n-1)+f(n-2)
ie the third no in series=0+1=1, fourth number =1+1=2,fifth number=1+2=3
This can be solved in java by implementing the following source code. With this, you have successfully completed the week 1 second program of your Jntu CSE/IT 2-2 Syllabus.

//The below program is used to generate the nth number in the fibonacci series
class Fibonacci //define class
{
public static int Fib(int n)//the function taking n as parameter
{
if(n>2)
return (Fib(n-1)+Fib(n-2));//the formula for all n>2
else
return 1;//if n=1 => f=1
}
{
public static void main(String[] args)

int n=Integer.parseInt(args[0]);//The first argument is read as 'n'
int val=Fib(n);//The fibonacci no. is stored in 'val'
System.out.println("The "+n+"th"+" value in the series is "+val);//Display the fibonacci no.
}
}
The out put of the program will be as follows:

Output:
save the above file as Fibonac.java in a note pad.
Press the start button, click on run.
Enter cmd and click enter.
Now type d: and click enter
type cd education and press enter
type cd java and press enter
Excecute it.
D:\education\java>javac Fibonac.java
D:\education\java>java Fibonac 10
The 10 th value in the series is 55
