how to call One constructor from another;..

Answer / ajay

Hi,

Using super you can invoke constructor which is in parent
class. to invoke constructor which is in the same class we
have to use this. for example:

public class Point {
int m_x;
int m_y;

//============ Constructor
public Point(int x, int y) {
m_x = x;
m_y = y;
}

//============ Parameterless default constructor
public Point() {
this(0, 0); // Calls other constructor.
}
. . .
}

Answer / tulasi prasad

We can call the parent class constructor from the child
class constructor.

class Parent
{
int a;
Parent(int x)
{
a=x;
}
}
class Child extends Parent
{
int b;
Child(int x,int y)
{
super(x);
b=y;
System.out.println(a);
System.out.println(b);
}
}

{
public static void main(String args[])
{
Child obj = new Child(1,2);
}
}

how to call One constructor from another;..

Answer / talk2sreenivas@gmail.com

. In one constructor, the first statement can be a call on
another constructor in the same class (use keyword this
instead of the class-name) or a call on a constructor of the
superclass (use keyword super instead of the class-name). In
a constructor for a subclass, the first statement must be
either this(…); or super(…); —if not, the call super(); is
automatically inserted for you.

Answer / talk2sreenivas@gmail.com

I think we find that anything you could have done in Java by
calling the default constructor from another constructor,
you can do easily in Curl by calling the default constructor
from a factory.
