Fibonacci Series in Java

Java Program to print Fibonacci Series

Fibonacci series is in the form of 0, 1, 1, 2, 3, 5, 8, 13, 21,...... To find this series we add two previous terms/digits and get next term/number.

import java.util.Scanner;
class Fibonacci 
{
public static void main(String[] args) 
{
int i,no, first=0, second=1, next;
Scanner s=new Scanner(System.in);
System.out.println("Enter number of terms for Series: ");
no=s.nextInt();
first=0;
second=1;
System.out.println("Fibonacci series are: ");
 for(i=0; i<no; i++)
 {
  System.out.println(first);
  next = first + second;
  first = second;
  second = next;
  }
}
}

Enter nubmer of terms for Series: 
5
Fibonacci series are:
0
1
1
2
3

Syntax to compile and run java program

for compile -> c:/>javac Fibonacci.java
for run -> c:/>java Fibonacci

Explanation of Code

• Scanner s=new Scanner(System.in): are used for receive input from keyboard.
• nextInt(): method are used for get integer type value from keyboard.
• System.out.println("....."): are used for display message on screen or console.
