Oh man I’m trying to figure this out for so many nights but still can’t…

Well think I’m lucky enough to accidentally enter at your site.

I already add your site to my favorites.

Thanks!!

can u make program in Fibonacci using array program in java that will input numbers….

Im looking for the same thing!

I tried on my own, but i cant get it to work, any tips?

this program is right

import java.io.*;

class Fibon

{

public static void main(String args[])

{

int i,n;

Console con=System.console();

System.out.print(“enter how many fibonacci no

u want to print “);

n=Integer.parseInt(con.readLine());

long a[]=new long[n];

a[0]=0;

a[1]=1;

for(i=2;i<n;i++) {=”” a[i]=”a[i-1]+a[i-2];” }=”” system.out.println(“fibonacci=”” series=”” upto=”” “=”” +=”” n);=”” for(=”” i=”0;” i<=”” n;=”” i++){=”” system.out.print(a[i]=”” +=”” “=”” “);=”” }=”” }=”” }=””>

import java.io.*;

public class Fibanocci

{

public static void main(String args[])

{

try

{

//Getting limit from the user…

BufferedReader limitOfFibObject = new BufferedReader(new InputStreamReader(System.in));

System.out.println(“Enter the Limit for fibanocci : “);

int limitOfFib = Integer.parseInt(limitOfFibObject.readLine());

//hard coding the limit…

//int limitOfFib = 5;

int[] fibSeries = new int[limitOfFib];

fibSeries[0]=0;

fibSeries[1]=1;

for(int i=2; i<limitoffib ;=”” i++)=”” {=”” fibseries[i]=”fibSeries[i-1]+fibSeries[i-2];” }=”” system.out.println(“fibonacci=”” series=”” till=”” “+limitoffib);=”” for(int=”” i=”0;” i<limitoffib;=”” i++)=”” {=”” system.out.print(fibseries[i]=”” +=”” “=”” “);=”” }=”” }=”” catch(exception=”” e)=”” {=”” system.out.println(“exception=”” is:”+e);=”” }=”” }=”” }=””>

import java.io.*;

import java.util.*;

public class Fibonacci {

public static void main(String[] args) throws Exception {

BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));

System.out.print(“Enter value of n: “);

String st = reader.readLine();

int num = Integer.parseInt(st);

int f1=0,f2=0,f3=1;

for(int i=1;i<=num;i++){

System.out.println(f3);

f1=f2;

f2=f3;

f3=f1+f2;

}

}

}

your program calculating 19 numbers only please modify.

can you create a program using fibonacci formula ..

the output should be like this

first : 1

Second: 3

Limits : 5

out pout is 1,3,4,7,11

plese help me ðŸ™‚

int result = 0, oldVal = 0, newVal =1, limit =5, temp=0;

while(newVal < limit) {

temp = oldVal;

result = newVal + oldVal;

oldVal = newVal;

newVal =result;

System.out.println(“Fib (“+ temp +” + “+ oldVal +”) -> ” + result);

}

this program is absolutely right.

nice easy to understand huh!

cool man i love you!!

Here is recursive way of generating Fibonacci Series in Java , its a natural example of recursion.

for my assignment..cool man !!

any other types of loop?

I like it’s very good

Wow!

Thanks you for this example.

how about this program can you create.

java program that will accept 2 numbers and print out in fibonacci serries:

example:

enter 1st term:

3

enter 2nd term:

5

output.

3 3 6 9 15

int f1, f2, f3;

f1=f2=3;

System.out.println(f1);

System.out.println(f2);

int i=1;

while(i<=3)

{

f3=f1+f2;

System.out.println(f3);

f1=f2;

f2=f3;

i++;

Another way without using an array. Nothing wrong with the array, just for practise.

for(int i=0, j=1, k=1; k<4182; k = j + i){

if(i==0)

System.out.print(i + ” ” + j + ” “);

System.out.print(k + ” “);

i = j;

j = k;

}

To add numbers of series

how and which purpose we are using %

For user input Fibonacci series:

import java.util.Scanner; // user input as well as output

public class MyFibonacci

{

public static void main(String args[]) // main method

{

//declare and initialise variable

int febCount;

febCount = 0;

Scanner input = new Scanner(System.in); // create Scanner

System.out.print( “How much fibonacci numbers do you want?” ); // user input

febCount = input.nextInt(); // store input in febCount

// array of frequency counters

int[] feb = new int[febCount];

// create first two series elements

feb[0] = 0;

feb[1] = 1;

//create the Fibonacci series and store it in an array

for(int i=2; i < febCount; i++)

{

feb[i] = feb[i-1] + feb[i-2];

}

for(int i=0; i< febCount; i++)

{

System.out.printf(“%8d%10d%n”, i+1, feb[i] ); // displays output vertically

}

}

}
