Question 112 / 297: What is the result of compiling and running the following code?

class Base {
	
	public Base(String n)   {System.out.print("Base1");}
	public void Base(String n) {System.out.print("Base2");}
	
	
}

public class Derived extends Base {
	
	public Derived() {System.out.print("Derived");}
	
	public static void main(String[] args) {
		new Derived();
	}

}

A Base1Derived

B Base2Derived

C Derived

D Compilation error

<< First < Previous Next > Last >>

Explanation:

The constructor Derived() will call first super(), but since there is no default constructor defined in class Base, because there is already an explicit declaration for a constructor, a compilation error arises
