Information & Algorithm

Given Input:

Expected Output:

Fibonacci Series:
0 1 1 2 3 5 8 13 21 34

Program Code

public class FibonacciSeries {

    // Method to print Fibonacci series
    public static void printFibonacci(int n) {
        int first = 0, second = 1;

        System.out.println("Fibonacci Series:");

        for (int i = 1; i <= n; i++) {
            System.out.print(first + " ");

            int next = first + second;
            first = second;
            second = next;
        }
    }

    public static void main(String[] args) {
        int terms = 10;   // Number of terms passed as parameter
        printFibonacci(terms);
    }
}

How to learn from this program

First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.

Practice suggestion

After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
