Java - Static Keyword

Identify the error in this code:

class Demo {
    static void show() {
        System.out.println("Hello");
    }
    public static void main(String[] args) {
        show();
        Demo d = new Demo();
        d.show();
    }
}

ACannot call static method using object reference

BMissing return type in show method

CNo error, code runs fine

DStatic method cannot access System.out

Step-by-Step Solution

Solution:

Step 1: Check static method calls
Static methods can be called using class name or object reference. Both show() and d.show() are valid.
Step 2: Verify method declaration and usage
The method show() has correct return type void and uses System.out.println correctly.
Final Answer:
No error, code runs fine -> Option C
Quick Check:
Static methods callable via object or class = B [OK]

Quick Trick: Static methods can be called via object or class name [OK]

Common Mistakes:

Thinking static methods can't be called on objects
Assuming missing return type error
Believing static can't use System.out
