How to get first N Fibonacci terms in Java?

Problem Description :

Write a program in java that prints first N Fibonacci terms.

Java program that generates first N Fibonacci terms.

First N Fibonacci terms in Java

Concept :

In Fibonacci sequence every number after the first two terms is the sum of the two preceding terms and it is defined by following recurrence relation.

F(N)=F(N-1)+F(N-2)

For example - First 10 Fibonacci terms are 1,1,2,3,5,8,13,21,34,55.

Java Program :

package com.javamultiplex.number; import java.util.Scanner; /** * * @author Rohit Agarwal * @category Number Problems * @problem How to get first n fibonacci numbers? * */ public class FibonacciNumbers { public static void main(String[] args) { Scanner input = null; try { input = new Scanner(System.in); System.out.println("Enter limit : "); int limit = input.nextInt(); if (limit >= 2) { int fib[] = new int[limit]; fib[0] = 1; fib[1] = 1; for (int i = 2; i < limit; i++) { fib[i] = fib[i - 1] + fib[i - 2]; } System.out.println("First " + limit + " Fibonacci numbers are : "); for (int i = 0; i < limit; i++) { System.out.print(fib[i] + " "); } } else { System.out.println("Limit should be >= 2"); } } finally { if (input != null) { input.close(); } } } }

Output :

Output - How to generate first n Fibonacci terms in Java?
