Answer Posted / hanu
there is an exceptional case for this.i.e when you call
derived class parameterised constructor and if you do not
call any of the super class constructor then bydefault the
superclass default constructor gets executed prior to the
derived argument constructor then the derived class
parameterised constructor gets executed.
example code:
class A
{
A()
{
System.out.println("in Class A");
}
A(int c)
{
System.out.println("in Class A"+c);
}
};
class B extends A
{
B()
{
System.out.println("in Class B");
}
B(int z)
{
System.out.println("in Class B"+z);
}
};
class Dead
{
public static void main(String[] args)
{
System.out.println("Hello World!");
//B b=new B();
B d=new B(20);
}
}
output:
---------- java ----------
Hello World!
in Class A
in Class B20
