Discussion Forum : Declarations and Access Control - Finding the output (Q.No. 3)
3.
What will be the output of the program?
public class A
{
void A() /* Line 3 */
{
System.out.println("Class A");
}
public static void main(String[] args)
{
new A();
}
}
Answer: Option
Explanation:
Option D is correct. The specification at line 3 is for a method and not a constructor and this method is never called therefore there is no output. The constructor that is called is the default constructor.

A() is a method not a constructor. So, the anonymous object created is not calling method A(). The code will execute without any output.

Unlike C++ in Java we can have method name same as of class name.
But like C++ constructor doesn't have return type not even void.

class a
{
void a(){}
}
a()
{}
}
is both of the methods are constructor of class a, if not why?
{
void a(){}
}
a()
{}
}

Because constructor doesn't specify return type.
