Re: Where and when do struts call the method named toString()?
Thanks for that info. I was aware that the hashcode SHOULD be unique for each object (depends on how one overrides the method tho'). I wasn't aware that the default implementation returned the memory address (should have researched a little deeper!). Good to know. I guess my original assumption was correct after all. But I guess that still leaves your original question about how to get the address unresolved.

Re: Where and when do struts call the method named toString()?
Thanks Dave. The default hashCode() implementation returns the objects memory address. As soon as your object or one of it's parents has overridden it you've lost it, but if you override hashCode (done when using hashmaps) it should still return a unique value so it's fine for determining if 2 objects are the same or not. --- dderry <[EMAIL PROTECTED]> wrote: > Just so happens that I was curious about this myself the other day.

Re: Where and when do struts call the method named toString()?
Just so happens that I was curious about this myself the other day. I found this in the javadocs for Object.toString(): this method returns a string equal to the value of: getClass().getName() + '@' + Integer.toHexString(hashCode()) So it appears that you don't really get an object pointer after all (as I also thought, must be that C++ background coming through ;-} ). Just call hashCode() when you want to get that 'object pointer'.

Re: AW: Where and when do struts call the method named toString()?
I guess so - I only used it in comparators for sorting collections so think oif
it as being a value not address compare.
The lesson I learn here (apart from go do more homework!) is you really ought
to check before making assumptions about how all these things are implemented.
Also be consistent in your app.

RE: Where and when do struts call the method named toString()?
OK I'll read Joshua's book after reading the other things listed below! oh boy!
I like Bruce Eckels Thinking in Java.
Looks like I might be having to read up on Swing - oh no! Last time I used it
(on windows) it couldn't draw the screen behind the cursor properly & left bits
of menu all over the place, made my beautiful app look a mess. Hope they've
fixed all that by now! (any know this stuff or where it's discussed?).
I'll have to try to pursuade them to use struts & forms!!
=
Oh yeah I remember why I used print instead of toString - coz in collections &
big classes I had printFull & printShort debug methods.
I should have had:-
void toString() {
print("heres a bit of the data");
print("if you want more - call toBloodyGreatLongString");
}
void toBloodyGreatLongString() {
etc..
}
Nothing more annoying than asking for a print or some diagnostics & getting
flooded by messages.
Does anyone know how to get the object pointer from inside toString so I can
make my toString print:-

RE: Where and when do struts call the method named toString()?
Not if you include a boolean value as a result of instanceof.
Note that you don't always want to override equals() (in which
case equals() is equivalent to ==), but when a class has a
notion of logical equality that differs from mere object
identity, and a superclass has not already overridden equals()
to implement the desired behavior (like value classes such as
Integer or Date, but not typesafe enum classes). Check out
pp. 25 - 35 in Joshua Bloch's "Effective Java" (one helluva
good book!!).

RE: Where and when do struts call the method named toString()?
For once, I disagree with Keith. :-(
You should always override toString. The general contract
in the "Java Language Specification for toString says that
the returned string should be "a concise but informative
representation that is easy for a person to read," and "it is recommended
that all subclasses override this method."
To compare classes, use boolean equals( Object obj).

Where and when do struts call the method named toString()?
Hi all,
in struts-example, Subscription.java file contains the following method:
/**
* Return a String representation of this object.
*/
public String toString() {
StringBuffer sb = new StringBuffer("Subscription[username=");
sb.append(username);
if (host != null) {
sb.append(", host=");
sb.append(host);
}
if (user != null) {
sb.append(", user=");
sb.append(user.getUsername());
}
sb.append(", autoConnect=");
sb.append(autoConnect);
sb.append("]");
return (sb.toString());
}
I can understand the method,but where and when does struts use it?
Thanks in advance
Laker
