Fibonacci Numbers

Problem statement:

Program to print first n Fibonacci Numbers

public class Test {
    // Method to print first n Fibonacci Numbers    static void printFibonacciNumbers(int n) {
        int f1 = 0, f2 = 1, i;
        if (n < 1)
            return;
        for (i = 1; i <= n; i++) {
            System.out.print(f2 + " ");
            int next = f1 + f2;
            f1 = f2;
            f2 = next;
        }
    }
    public static void main(String[] args) {
        printFibonacciNumbers(7);
    }
}

Output:

1 1 2 3 5 8 13
