No. Java made a decision to not make primitive types and object
references convertible to booleans. In fact, it differs from its
predecessors in having a boolean type that is not merely a special case
of the integer. Merely omitting an "=" may have been one of the factors,
but there are several others, most notably an increased sense of type

I am still not clear as to what is actually doing this.
I have done some additional testing and found that this only happens
when using a JSP document (XML). If I do this in a plain JSP page or
in an HTML page, then it all works fine and the script element is sent
to the browser as I entered it.
Should I not be using a jsp:root declaration? All of the

Yes. An expression is a series of values (literals, variable references,
etc.) joined by operators. Essentially, if <x> and <y> are expressions,
and <op> is an operator, <x> <op> <y> is an expression [1]. So what are
operators? There are arithmetic operators (+, -, *, and /), bitwise
operators (&, ^, |), assignment operators (=, <op>=), and... Hey, wait,

Hi,
If you meant to say that even if you set it to readonly in windows
explorer, then you still can create a file in it, then you can forget it,
because if the OS does not support blocking the file creation then you
will never be able to do it in Java.
If you meant to say that setting readonly through Javas setReadOnly()

Indeed.
It's useful as a form of currying. And it's purely up to a
language designer or a library designer's choice. And it's
purely subjective and depends on individual's taste.
For example, even method calls can be curried.
Suppose you have a File object, which has a "write(String)" method.
Now, the library designer could have implemented it

Why not? Whether you like it or not, the assignment operator does in Java
create an expression with a type.
It could be argued that Java should not have inherited that particular
convention from C; after all, Java abandoned other conventions, such as

I am, but how is that relevant? This is a Java newsgroup.
You base that claim on what evidence? I don't know the specifics myself,
but it's not uncommon for a language interested in type-safety to do fewer
implicit type conversions than would, for example, C. And in particular,

It's not a variable. Plenty of non-variable things have types. 5 is not
variable, yet it clearly has a type of |int|. Things that have types are
called `expressions', and assignments are expressions in MANY languages,
including (but not limited to):
* Awk
* C
* C++
* Java
* Javascript (sorry, ECMAScript)

You are right, I have to make a correction. Not only (explicitly
declared) variables have a type, but also expressions over the
variables; e.g given "int x,y;" the expression "x+y" is of type int.
Now is assignment realy an expression? I don't mean that you answer
that by trivially checking your favorite language grammar. Expression

Okay, fine: Nobody here is forcing you to use Java.
But if you're writing about some language other than Java,
you'll find better audiences and get better discussions in
newsgroups devoted to those other languages. At the very least,

kenny.rio...@gmail.com (Kenny Riodan) — Fri, 05 Sep 2008 21:18:23 UT

What are you on about?
Of course assignment is not a variable.
Assignment is an expression.
C, C++, and Java all disagree with you here.
int a, b, c;
a = b = c = 7;
which is parsed into
a = (b = (c = 7));
which means
c=7;
a = (b = 7);
which means
c=7;
b=7;
a=7;

_Learning Java_ by O'Reilly is pretty good. It is an introductory book,
so it doesn't cover things in a lot of depth. But what it does cover it
generally tries to go beyond the simplest approach and give some hints
how best to use it.
For example, it has one of the better explanations of generics I've
