Here is my program and results and I am having a error on line 38 which is "public static long fib01(long paramLong)" The program does give me my results but I am trying to correct there error.
public static void main(String[] args) { { System.out.print("
" + String.format("%-10s", new Object[] { "Index" })); System.out.print(String.format("%-15s", new Object[] { "Fibonacci01" })); System.out.print(String.format("%-15s", new Object[] { "Fibonacci02" })); System.out.println(String.format("%-15s", new Object[] { "Fibonacci01" }));
I need to write a JAVA program and algorithm that writes the numbers from 1 to 1000. Then I ned to write another one that writes the numbers from 1 to 1000, but 5 by 5. ( example 5,10,15,20,25,30)....
I have to write a program that find the sum of two numbers 62 and 99 and stores them in a variable named total. However, I have one error that I just can't get rid of and can't tell what it is. I'm using jGrasp and here's what it says:
Programming Challenge #5.java:14: error: class SumofTwoNumbs is public, should be declared in a file named SumofTwoNumbs.java public class SumofTwoNumbs { ^ 1 error ----jGRASP wedge2: exit code for process is 1. ----jGRASP: operation complete.
and here: is my code:
import java.util.Scanner; /* * To change this license header, choose License Headers in Project Properties. * To change this template file, choose Tools | Templates * and open the template in the editor. */ /** // This program has variable of several of the integer types. public class SumofTwoNumbs { public static void main(String[] args) {
I am trying to write a program that takes two numbers and multiplies them. I got this idea from this running conversion program
import java.util.Scanner; public class Convert { public static void main (String [] args) { Scanner reader = new Scanner (System.in); double farenheit; double celsius;
[code]...
i am getting a cant find symbol for the output = (alpha*beta) line..Also, am I using the reader object correctly ? hould I create two reader objects as there are 2 inputs needed?
I'm going to be taking an object oriented paradigm using java during intersession in a few months. I'm trying to brush up on it a bit. The problem is. Write an application that displays the numbers 1 to 4 on the same line, with each pair of adjacent numbers separated by one space. Write the program using the following techniques:Use one system.out.printLn statement.Use four system.out.print statement.Use one system.out.printf statement.
This is what i have so far .
Java Code: public class Display { public static void main(String [] args) { System.out.print("1 "); System.out.print("2 "); System.out.print("3 "); System.out.print("4 "); System.out.println(" ");<----is that what that is supposed to look like, and where it goes? System.out.printf(" %s %s %s %s ");???? } } mh_sh_highlight_all('java');
i cant test this my console isn't working right, and i haven't finished my compiler install.
So i need to write a program that prompts the user for 3 double numbers x, y, z that outputs 2x^3 + 3y^5 + 3x^3y^2 +xyz with
(1) 4 digits precision (2) with a ',' to separate thousands (3) all digits of the result including the precision are put to 20 positions (from right to left)
I am not really sure what it is suppose to look like or how to start it.how to mix Math.pow with multivariable and printf.
public class FibSeqByIanNeumann { public static void main(String[] args) { Scanner get = new Scanner(System.in); int ctr, num1, num2, fib, maxTimes; System.out.print("How many sequences do you want?: "); maxTimes = get.nextInt(); //inputs the maxium limit of the fib sequence
[code]....
how to do a simple YES/NO Loop so I can try to have it work on my code if I want to try to do the Fibonacci Sequence again.Now I think it might have something to do with a do/while loop.
I need to write a For Loop that prints out the first 12 Fibonacci numbers:1 1 2 3 5 8 13 21 34 55 89 144.The problem I am having is that I can not get the first two 1 numbers. I only get 1.2.3.5.8.....
int a=1; int b=1; for (int i=1; i<12;i++) { System.out.print(a+" "); a=a+b; b=a-b; }
Do I need to add another For Loop that sub-tracks so that I can get the first digit of 1?
public class E09_Fibonacci { static int fib(int n) { if (n <= 2) return 1; return fib(n-1) + fib(n-2); } public static void main(String[] args) { // Get the max value from the command line: int n = Integer.parseInt(args[0]); if(n < 0) { System.out.println("Cannot use negative numbers"); return; } for(int i = 1; i <= n; i++) System.out.print(fib(i) + ", "); } }
please break down fib method shown above. I can't understand how the magic is happening inside that recursion.
public class Fibonacci { public static void main(String[] args) { int[] numbers; numbers = new int[20]; numbers[0] = 0; numbers[1] = 1; System.out.println("

I wrote this program for my Java class to print out the first 20 numbers of the Fibonacci series. My assignment then tells me to Rewrite your program using dynamic array. I'm not sure how to do this.
Its a program that calculates Fibonacci number.This program uses recursion.
import java.util.Scanner; public class FibonacciMemoization{ static int[] fib = new int[60]; public static void main(String[] args){ Scanner input = new Scanner(System.in); System.out.print("Enter a Number :"); int number = input.nextInt();
I am attempting a programming exercise to display the values in the Fibonacci sequence from F0 to F15. I understand the concept, but, for some reason my equation is simply creating a resulting string of numbers that simply increase by 2's. As, I know it is supposed to be the sum of the previous F and the F that precedes that one to total the new F number. It seems so simple yet I seem to be far off. As usual, I have worked my code for your review.
/* * This program calculates the "Fibonacci sequence." * A "sentinel" is used to limit the extent the calculation. */
import acm.program.*; public class bookFibonacciTest2a extends ConsoleProgram { /* Specifies the limit value of the calculations */ private static final int SENTINEL = 16; public void run() { println ("This program display Fibonacci sequence numbers 0 - 15.");
I have to find where in the fibonacci sequence a at number belongs, using a if or while loop.
Example
>55 is a Fibonacci number whose order in the sequence is 11 >35 is not a Fibonacci number. However, it lies between Fibonacci numbers 34 (order: 10) and 55 (order: 11)
import java.util.Scanner; public class While { public static void main(String[] args) { System.out.println("Welcome to the Fibonacci Sequence Detector"); Scanner in = new Scanner(System.in);
I wrote this tail recursive function that mirrors the iterative version, except that the loop in the iterative version is replaced by an if statement here and then a recursive call. Is this truly recursive? I have seen the fibo(n-1) + fibo(n - 2) version, but is this also an acceptable recursive solution? Why is it never solved this way?
public class FiboRecursive { public static int fibo (int n) { int sum = 0; int n1 = 1; int n2 = 1; if (n == 1 || n == 2) { sum = 1;
Write a recursive method that calculates the Nth number in the Fibonacci sequence. The first and second numbers in the sequence (the base cases) are both 1. After that, each subsequent number is the sum of the previous two. Stated a bit more formally:
fib(n)={1fib(n−1)+fib(n−2)n<2otherwise
For example, here is the first few numbers in the sequence:
1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ...
Your fib method should be part of a class named Fibonacci. In addition to the fib method, the Fibonacci class should have a main method that calls fib(9). If the result doesn't equal 34, you should print an error message. Otherwise, it should print out a message saying that it was successful.
After writing your Fibonacci class, answer the following question: How many times is the fibonacci method called when calculating the 5th number in the sequence?
I have to find where in the fibonacci sequence a at number belongs, using a while loop.
Example
>55 is a Fibonacci number whose order in the sequence is 11 >35 is not a Fibonacci number. However, it lies between Fibonacci numbers 34 (order: 10) and 55 (order: 11)
import java.util.Scanner; public class While { public static void main(String[] args) { System.out.println("Welcome to the Fibonacci Sequence Detector");
Write a program that detects Fibonacci numbers. Prompt the user to input a positive integer. Upon input, the program will determine if the number is either a Fibonacci number or not. If a Fibonacci number, then the order of the number in the sequence must be output. If not a Fibonacci number, then the Fibonacci numbers above and below it (including their order in the sequence) must be output. Once it finishes, the program will prompt the user for a new number. The program will exit if the user enters a string (such as “quit”) instead of an integer. Use the sample output file, fib-seq-det.txt, to view a sample session
This is my project, I wrote a programs that tells you if the input number is a fibonacci number or not. For some reason it only works for some Fibonacci numbers but not all of them.
import java.util.Scanner; public class While { public static void main(String[] args) { System.out.println("Welcome to the Fibonacci Sequence Detector "); Scanner in = new Scanner(System.in); System.out.print("Please input a number for analysis: "); int input = in.nextInt();
I have to create a program that calculates the nth Fibonacci number and returns that to the user. Fibonacci said his number sequence would describe the ideal breeding patterns of immortal rabbits. So, you are going to make this vision a reality.
First, take in a numeric value from the user and calculate that value in the fibonacci series. Next, find an image of a rabbit and display the image on a GUI (put the image as an icon on a label!) the number of times returned by the algorithm (Put all the aforementioned labels on one panel with FlowLayout!).
You need to remove the old images from the Panel. Probably the easiest way to do this is to create a whole new panel and remove the old one (hint: the remove method of JPanel should come in handy)
You could use an array of JLabels You will need to create a new JLabel and add each member of the array to the panel I should be able to scroll to see any images that are off screen
I am having difficultly on to making the array list for JLabel, and getting the Fibonacci sequence to show the pictures of rabbits. Below is my current code.
import java.awt.FlowLayout; import java.awt.*; import java.awt.event.*; import javax.swing.*; public class Rabbit extends JFrame
Modify the Improved Fibonacci application to store its sequence in an array. Do this by creating a new class to hold both the value and a boolean value that says whether the value is even, and then having an array of object references to objects of that class.
Did I just need to declaring the variable in other class (for boolean value and the value itself) or else ?
Here is the code for ImprovedFibonacci.java
Java Code:
class ImprovedFibonacci { static final int MAX_INDEX = 9; /** * Print out the first few Fibonacci numbers, * marking evens with a '*' */ public static void main(String[] args) { int lo = 1; int hi = 1; String mark;
