explain the following code;

public class Fibonacci {

public static void main(String[] args) {

int n = 10;

for (int i = 0; i < n; i++) {

System.out.print(fibonacci(i) + " ");

}

}

public static int fibonacci(int n) {

if (n == 0) {

return 0;

} else if (n == 1) {

return 1;

} else {

return fibonacci(n - 1) + fibonacci(n - 2);

}

}

}
