Q. Write a Java program to generate Fibonacci Series using for loop

 import java.util.Scanner;

public class FibonacciSeries {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);

        // Ask the user how many terms to display
        System.out.print("Enter the number of terms for Fibonacci Series: ");
        int n = scanner.nextInt();

        int first = 0, second = 1;

        System.out.println("Fibonacci Series up to " + n + " terms:");

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

Q. Write an algorithm to generate Fibonacci Series using for loop

1. Start
2. Read an integer n (number of terms)
3. Initialize first = 0, second = 1
4. Repeat from i = 1 to n:
    a. Print first
    b. Compute next = first + second
    c. Set first = second
    d. Set second = next
5. End
