Java | Functions | Question 1

Output of following Java program?

class Main {
    public static void main(String args[]) {
             System.out.println(fun());
    }

    int fun()
    {
      return 20;
    }
}

(A) 20
(B) compiler error
(C) 0
(D) garbage value


Answer: (B)

Explanation: main() is a static method and fun() is a non-static method in class Main.

Like C++, in Java calling a non-static function inside a static function is not allowed
