Java Program to Display Fibonacci Series

πŸ™‹ Introduction

The Fibonacci series is a sequence of numbers in which each number is the sum of the two preceding ones, usually starting with 0 and 1.

This series has widespread applications in various fields, including mathematics and computer science.

In this tutorial, we'll explore a Java program that generates and displays the Fibonacci series.

πŸ“„ Example

Let's delve into the Java code that generates and displays the Fibonacci series.

FibonacciSeries.java
Copied
Copy To Clipboard
public class FibonacciSeries {

  // Function to display Fibonacci series up to n terms
  static void displayFibonacci(int n) {
    int first = 0, second = 1, next;

    System.out.print("Fibonacci series up to " + n + " terms: ");

    for (int i = 0; i < n; ++i) {
      System.out.print(first + ", ");
      next = first + second;
      first = second;
      second = next;
    }

    System.out.println();
  }

  // Driver program
  public static void main(String[] args) {
    // Replace this value with the desired number of terms
    int terms = 10;

    // Call the function to display Fibonacci series
    displayFibonacci(terms);
  }
}

πŸ’» Testing the Program

To test the program with a different number of terms, simply replace the value of the terms variable in the main method.

Output
Fibonacci series up to 10 terms: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34,

Compile and run the program to see the Fibonacci series up to the desired number of terms.

🧠 How the Program Works

  1. The program defines a class FibonacciSeries containing a static method displayFibonacci that takes the number of terms (n) as input and prints the Fibonacci series up to n terms.
  2. Inside the method, it initializes variables first and second with 0 and 1, respectively.
  3. It then uses a loop to calculate and print the Fibonacci series up to the specified number of terms.
  4. The loop updates the values of first and second in each iteration to generate the next Fibonacci number.

🧐 Understanding the Concept of Fibonacci Series

The Fibonacci series starts with 0 and 1. Each subsequent number in the series is the sum of the two preceding ones. The series begins as follows:

0, 1, 1, 2, 3, 5, 8, 13, 21, ...

🎒 Optimizing the Program

While the provided program is straightforward, consider exploring and implementing optimizations for larger Fibonacci series, such as using memoization techniques to avoid redundant calculations.

Feel free to incorporate and modify this code as needed for your specific use case. Happy coding!
