OK, I finally caught up to JAVA 1.5/6. (Delay had to do with available
tools and my intolerance for Eclipse, but I have reconciled myself to it now).

Question: Eclipse gives me a compiler error for:

List list = new ArrayList();
for (String s : list)
System.out.println(s);

It says "Type mismatch: Cannot convert from element type Object to
String". It's fine if I change decl of list to List<String>, or coerce
list to List<String> in the loop decl;

Is this an *actual* compiler error in the JAVA spec? Is JAVA actually
that hissy about the for-each variable? The compiler does not mind the
code below, even though it causes a runtime type-cast error. So why
can not it insert the cast to String in the loop setup? Am I missing
something?

Dave

List ar = new ArrayList();
ar.add(1);
List<String> list = ar;
for (String s : list)
Utils.log(s); read more about No coercion in for-each loop?

Hello,
I have built a web service in eclipse.

From one service, all I do is

try {
Class.forName("oracle.jdbc.driver.OracleDriver");
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

But then I get the following exception:
JAVA.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver

I use Oracle 9.x, I have classes12.zip in my class path, I tries to
change it to classes12.jar, I tried to put it under tomcat local
directory and to point the path to there, but nothing worked.

Interesting is the fact that if I run the same code exactly outside
the web service method, for example from the test class main function,
everything is fine. So I suspect it is a configurable issue. But what
is it???

If I have a class such as:
------------------
public class MyClass
{
public MyClass()
{
super();
}

public void printThis(String parm)
{
System.out.println(parm);
}
}
------------------

I can run the method like this:

(new MyClass()).printThis("Hello World");

Since printThis only uses passed parameters, I could also have this:
------------------
public class MyClass
{
public MyClass()
{
super();
}

public static void printThis(String parm)
{
System.out.println(parm);
}
}
------------------
and then I can run the method like this:

MyClass.printThis("Hello World");

Both ways are valid, and functionally equivalent. The main difference
being that the first way instantiates a class whereas the second does
not.

Thoughts?

Hello

I have the following interface in my working directory (C:\JAVA>)

public interface Foo {
public void doSomething();
}

As you can see, there is no expicit package definition so this class is
in the default package. Why do I want to do this ? well it's part of an
exploration of classloading and the classloader architecture and for the
fist time in I do not know how many years I'm working on the command line
without Eclipse to tell me when I did something stupid.

To cut a long story short I wanted to refer to this interface in a
packaged class and I can not because you can not apparently use classes in
the default package from within a named package.

I'm trying to understand why this is but I'm not getting too far, I'm
sure I did know it once, a long time ago but I have sure forgoten it now.

Why can not you use classes in the default package from within a named
package.

A stream may have an underlying stream. For example,
FileOutputStream fos = new FileOutputStream("foo");
BufferedOutputStream bos = new BufferedOutputStream(fos);
fos is the underlying stream for bos.

Now if I call bos.close(), it'll also close its underlying stream.
Why should the underlying stream be closed? I can think of some cases
where I want to continue to write to the underlying output stream
after I close the "outer" output stream.

I know it's useful if people do
BufferedOutputStream bos = new BufferedOutputStream(new
FileOutputStream("foo"));
and you do not have a handle on the underlying stream. But you can
always define a variable for the underlying stream.

I have a method that allows the caller to pass in an output stream.
Then I want to use a BufferedOutputStream to write to it. After that,
I should close the BufferedOutputStream before exiting the method. But
that closes the output stream passed in by the caller and the caller
can no longer write to it. For example,
void foo(OutputStream out) {
try {
BufferedOutputStream bout = new BufferedOutputStream(out);
bout.write(blahblah);
}
finally {
bout.close(); // I should close any stream I created but
this closes the underlying stream, too.
}
} read more about Why should close() close the underlying stream?

I'm new to using XML in JAVA, so please forgive me if this is an easy
question.

I'm using NetBeans and I have written a unit test that just reads in an XML
document using the DocumentBuilder class. This is a document I have written
myself and I have written a DTD for it as well. So I'd like it to be
validated while being read. So, I have called the setValidating(true)
method on the DocumentBuilderFactory before getting the DocumentBuilder
itself.

The problem is that I do not know what to do with the DTD file so that it
will be found when the document is being parsed. The DocumentBuilder
does not know where the xml file came from so the current directory does not
seem right. There does not seem to be anywhere to load the dtd file so
that the builder will be able to find it.

I'm getting the following error which says to me that this is the
problem, but maybe I'm misreading it.

org.xml.sax.SAXParseException:
Document root element "onlinequiz", must match DOCTYPE root "null".

I'm sure that many of you use this stuff all the time. How'd you set
up a unit test to make sure a document is being parsed correctly? What do
you do with the DTD?

Thanks,

Hello,

I was playing with some code today, and then I hard-coded the line:
System.out.println(String.valueOf(null));

At first, I expected this line to call the overload
"String.valueOf(Object)", printing "null" to the output stream.
However, I noticed that it called the "String.valueOf(char[])"
overload, throwing a NullPointerException.

Although my first expectation is incorrect, I am thinking about why
the char[] overload was called automatically, and why the compiler
did not complain about this being an ambigious call, in the same way it
would do had there been another overload like
"String.valueOf(Integer)".

I guess this either has to do with the JAVA Language Specification, or
a decision made for the compiler. Could you please explain to me why
the compiler takes this behavior? In my opinion, it would've been
safer to complain about it. Am I wrong? Why?Thanks a lot for your help. read more about Why does "String.valueOf(null)" call the array overload?

Hi,

From 1.5 and on, does JAVA automatically intern strings?



During a recent team discussion, we thought we read somewhere that
this was added to 1.5 as default behaviour, but we weren't sure. By
automatically interning I mean that if you've String a = new
String("ABC") then

String str = new String("ABC")

is equivalent to

String str = a.intern();

Thus far, we've found nothing to say that this was added.

I have a JAVA app, running on Windows, with a medium amount
of C++ wrapper code doing various arcane and boring things.
JProfiler swears that there is not a memory leak in the JAVA.
Purify claims that there is not a memory leak in the C++. According
to ProcessExplorer, however, we leak memory (or rather, the
Private Byte and Working Set keep rising). Some of this might
be induced by memory fragmentation, I suppose, but other than
that and the thought that Sun's JVM might leak memory (possible?),
I'm not sure where to go.

I'm currently using Sun's 1.5 JVM. Client and Server mode does not
make much of a difference (the amount of memory used goes down,
but the increase remains). I have not tested extensively with 1.6,
but saw essentially the same behavior with my quick look.

Is futzing with the GC parameters going to accomplish anything?
Is this just expected behavior? Is the only solution to kill and
resume the app on a regular basis?

Let's say I have a proxy object. I want to know what's the interface
this proxy object was created with.

I know that I can check whether class is a dynamic proxy:

Proxy.isProxyClass(proxyObject.getClass())

But I want something like that:

Proxy.getInterfaces(proxyObject)

How can I do that? Is there a library that can help me? Or am I
missing something and this is very easy (yoopie!) or impossible
(errr.... let's get back to Ruby).

Thanks a bunch for any help!

I think it'd be nice if I could prove to someone on the other end
of the phone I am me, and demand they prove they are who they claim to
be.

It could be done by letting a modem kick in for a second to exchange
challenge phrases to be encrypted by identification certificate that
might include name, address, phone number, expiry date, company.

Then if some charity I donate to phone me, I can be sure it is them.

There are so many scams out there.

It might also be done by each of us contacting an Internet server.

Has anyone heard of such projects?

Hello,

On some platforms, file names cannot contain certain characters (eg. on
windows no ? is allowed in a file name and path).
Is there a way in the API (application programming interface)to sanitize a user-supplied string so that it
can be used as a valid filename?
Is there a way to test if a filename is valid on a certain platform?

Thanks Phil read more about Sanitize file name

I have a JSP Form with 15 inputs that is processed and emailed to
people.

I am using Enumeration to process and display the information. But I
need exact order of how the information is displayed and Enumerations
don't guarantee order so I have to do this:

Code: ( text )
Enumeration params = request.getParameterNames();
String text = "Form Information\n\n";
while (params.hasMoreElements()) {
//String name = (String)params.nextElement();
//String[] values = (String[])request.getParameter(name);
//String value = request.getParameter(name);
text += "First Name: " + request.getParameter("firstName");
text += "Last Name: " + request.getParameter("lastName");
text += "City: " + request.getParameter("city");
text += "County: " + request.getParameter("county");
text += "Project Info: " + request.getParameter("projInfo");
text += "Main Status: " + request.getParameter("mainStatus");
.....
.....
/*
if (values != null && values.length > 0) {
for (int i=0; i<values.length; i++) {
text += values + " ";
}
}
*/
}

//email the info
..........
EmailSender emailSender = new EmailSender();
emailSender.setFromEmail("info@xxxxxxxxxxx");
emailSender.setSubject(emailSubject);
emailSender.setText(text);
.........
Any better way?
Please advise because I dont have Struts and probably wont be allowed
to get it for a long time. read more about Enumeration of data

Hello everyone..
Here I am again for another question.. :P
Suppose we've the following class

public class Test {
private Test2 test2 = new Test2();
public void testMethod() {
test2.test2Method();
}
}

Is there a way, using anything (probably reflection) to know that the
method testMethod of this class calls test2Method() method of Test2
class..? Or the other way around.. Is there a way to know what classes
call Test2's method test2Method()..?

Any help/reference/book etc. is appreciated.
Thank you very much. read more about About Reflection (or not)

Hi all,

Is it possible to create a stream originating from a byte[] array? I looked
for "memorystream" and anything approaching and couldn't find it.
Basically, I have an array of bytes, and I'd like to read it via a
standart method that accepts streams as input.

Thanks! read more about Memory stream
