1: public class Salmon { 2: int count; 3: public void Salmon() { 4: count = 4; 5: } 6: public static void main(String[] args) { 7: Salmon s = new Salmon(); 8: System.out.println(s.count); 9: } }
✅ A. 0 ❌ B. 4 ❌ C. Compilation fails on line 3. ❌ D. Compilation fails on line 4. ❌ E. Compilation fails on line 7. ❌ F. Compilation fails on line 8.
Explanation: While the code on line 3 does compile, it is not a constructor because it has a return type. It is a method that happens to have the same name as the class. When the code runs, the default constructor is called and count has the default value (0) for an int.
