Constructor overloading???

[Panagiotis Karvounis]

I am not trying sth special.I am testing language features that I use with Java.

I was trying to use initialize more than once(think Java-default
constructor,other with one argument etc...)

Example with Java:

public class Rectangle
{
public int a,b;

public Rectangle()
{
a=0;
b=0;
}

public Rectangle(int c,int d)
{
a=c;
b=d;
}
}

So I tried:

class Rectangle

def initialize
@a=0
@b=0
end

def initialize(c,d)
@a=c
@b=d
end

end

But it was obviously not working.

What about this one?

For your help Greek words translation:


ypoxrewsi=duty
topos=place
diarkeia=duration
skopos=subject
hmera=day(date)
wra=time
emfanisi=print

Thanks so much for helping me.

class Rectangle
def initialize(a = 0, b = 0)
@a = a
@b = b
end
end

That will work very well for you.

You can do any number of other things like this that I find work as
well or better than actual argument overloading, mostly because Ruby
is dynamically typed.
