You are right Ashish...

We can not return any value from constructor...

A constructor does not return anything; the "new" operator returns an object that has been initialized using a constructor.

If you really want a constructor that may return null, perhaps you should check out the factory method pattern. A short example:

class MyClass
{
    // the constructor is private so it can only be called from code inside this class itself.
    private MyClass(int i)
    {
        ...
    }

    public static MyClass newInstance(int i)
    {
        if (i > 0)
        {
            return new MyClass(i);
        }
        // i <= 0
        return null;
    }
}
