Java - Interfaces

Find the error in this code snippet:

interface Shape {
  void draw();
}
class Circle implements Shape {
  void draw() { System.out.println("Circle drawn"); }
}

AInterface cannot have methods

BNo error, code is correct

CCircle class should be abstract

DMethod draw() must be public in Circle class

Step-by-Step Solution

Solution:

Step 1: Check method visibility rules
Interface methods are implicitly public, so implementing methods must be public too.
Step 2: Identify method visibility in Circle
Method draw() in Circle has default (package-private) visibility, missing public.
Final Answer:
Method draw() must be public in Circle class -> Option D
Quick Check:
Interface methods require public implementation = B [OK]

Quick Trick: Implement interface methods as public always [OK]
