Question { Wipro, 19822 }

Can a class inherit the constructors of its superclass?

Answer

import java.io.*;

class Parent
{
Parent()
{
System.out.println("This is super class Constructor");
}
}
class Code3 extends Parent
{
Code3()
{
System.out.println("This is child class");
}
public static void main(String ar[])
{
Code3 c=new Code3();
}
}

Here if i call the child class constructor,even the parent class constructor is implicitly invoked,that means constructors can be inherited.

feet=5280*miles;
inch=feet*12;
