Need to talk through some basic Java principles

I know this is asking a lot, but I need to talk to someone about Java basics. I have an interview coming up. I am studying, but really need to talk through some things with someone who is familiar with Java programming. My email address is [email protected] If someone could send me a telephone number and perhaps spend 30 minutes on the phone, I would be very greatful. Thanks!

I don't know if there are any forums where they help you fake your way through interviews.

Making some basic Java games

thanks,

Well, first of all you program the Framework, add Graphics / sounds / Data , then you put it in your HP - There you are!

Plese help! Stuck on some basic Java homework...

I am taking this introduction to java class and we were given 3 homework assignments and I am really stuck on 2 of them.
One of the assignments asks to make a index.html page that will connect to a mysql database for coffee/suppliers.
The first part says:
Create the index.html to create the following web page. After a user selects
Espresso and 5 pounds, and clicks �Submit Order� button, he/she is going to see the
following URL:
http://localhost:8080/hmwk09/coffee_processing.jsp?name=Espresso&pounds=5&Submit=Submit+Order
(which I sort of completed physically with dreamweaver. im not sure if i need to embed some java into that page.)
The second part which I am really stuck on says:
Create the coffee_processing.jsp that queries coffees and suppliers table (you created in homework 08) to display the following page:
This part is where it queries the mysql database that I did. The page is basically supposed to look like this (in a webpage format):
Here is the information about your order:
| Name | Supplier | Price |
| Espresso | The High Ground| 9.99 |
Number of Pounds: 5
Total Price: $49.95
(I really confused on what I need to do to create a jsp to do this. Thanks so much in advance!)

well, first create a jsp page that defines how the page will look. Then make use of a <jsp:useBean..> in combination with <jsp:getProperty....>
and <jsp:setProperty....> to access a bean that does the database fetching.

Basic java principle

hi,
I am a bit new in java and has written a number of java program already but now I wanna know the basic understanding of java working principle such I have written a simple java " hello world" printing progam and I want to know the exact step that the java compile handles the program write the bytecode and execute it. Also it would be great help if any body send some link to understand the principle of JVM too. thanks in advance....

This may help you a bit.. http://java.sun.com/docs/books/jvms/second_edition/html/VMSpecTOC.doc.html

Some basic java Questions

class overload
void test (long a)
System.out.print("\n\t\t Inside Integer..."+a);
class usetest
public static void main(String args[])
overload ob=new overload();
double i=88;
int j=54;
//ob.test(i); this do not work
ob.test(j); // works
The one that do not work when typecasted works why? When method having same parameter is not present what java compiler do?

The compiler will automatically perform a "widening" cast for you, i.e.
a cast from one type to another where no precision is lost. If you supply
an int and a long is wanted, the int will be cast to a long type.
Not so from double to long because that isn't a widening cast, it's a
"narrowing" cast because bits might get lost after casting. You have
to cast that double to a long explicitly, thereby telling the compiler that
you know what you're doing.
kind regards,
Jos

You aren't addressing anyone from Apple here. This is a user forum.
You might want to call a neaby Apple store to see if they have a free class you could attend.

Complete Novice Needs Some Basic Help

Hi!
I'm sorry to clutter up the discussion with such basic questions, but what I want to do is get something from a cassette tape to my iPod. I'm told I can do this through GarageBand, and I have an audio cable that the guy in the Apple store said I would need. I'm not even sure where to plug this cable in. So any help in where I plug this in, or what I do next would be tremendously appreciated. If someone could even tell me where to look for help that would be great (when I look in GarageBand help its saying something about MIDIs and I don't even know what that is). Eternal gratitude for any help....

Oh man, this is frustrating and I might give up soon!
So in System Preferences, Sound I have 2 things,
Internal Microphone (port is Built-in) and Line In
(port is Audio line-in port). I can't seem to
select one or the other, they're just there.
Yeah, there is no "apply" or "OK" or anything like that. Just click on the Line-In so that it is highlighted and close the system preferences. That takes care of that. My PB G4 automatically detects when I plug in my line-in now that it is set up.
Then in GB preferences, I only have the option of
Built-in Audio, there is no other option.
Built-In audio is correct in GB prefs.
I also couldn't find where you were saying to
double-click...what's the track header? I've clicked
everything and can't find a monitor drop down menu
option.
The track header is the left-hand side of the track where there is a small speaker or instrument. For what you are doing, you need to create a new basic track. (Under "Track" in the menu bar, click "New Basic Track") You should have a new blue track that is labeled "No Effects." Double click on the speaker image and a dialog box will appear. Right in the middle of this box there are options for Input, Volume, and Monitor. You can turn on and off monitor abilities here.
On the plus side, the connector I have seems to
work...its male/male 1/8".
Perfect.
Thanks again and if you want to bail out, I
completely understand!
Hang in there. We were once all newbies to this digital recording stuff too.

Need answers for some basic question

The Informatica server software usually runs on some server machine.The client tools usually run on those Windows PC with which developers to their work. That's a pretty much standard client/server architecture.On Windows servers you will often (not always) find the client tools as well, but that's by no means mandatory.Communication between PowerCenter clients and PowerCenter server usually takes place via TCP/IP; the protocol, as far as I know, has been developed by Informatica in-house app. in 1993-1995. The installation of the server software usually is the task of some server administration team. You will also need some DBA team because the Informatica software (almost) always stores its controlling, scheduling, and runtime information in some relational database system. Importing of relational structures (meaning table and view structures) usually is done on a client PC which connects to the respective source and/or target DBMS via ODBC.The server uses either native database client installations (for Oracle, IBM DB2, Microsoft SQL Server, and Sybase) or ODBC to communicate with the source / target databases. Best thing is that you download the documentation and start browsing the Installation and Configuration Guide; this PDF file explains quite a few concepts fairly well. Regards,Nico

Hi, 1) a server installation is a server installation and nothing else. It also contains some clients (namely the command-line client tools), but definitely not the GUI clients (this is an extra installation always to be done on a Windows PC as of this time).2) That depends on your business processes. Sometimes files will be placed in some directory (e.g. /opt/transfer/inp) and then the respective workflow shall start, so it might read this file directly. If some business user can only deliver via email, then you will need an extra process which extracts the file(s) from the email and places them somewhere where the server processes can access them.3) Unix is a computer operating system. Windows is a computer operating system. They are just in use in different cases (at least often). Some basic Unix knowledge (about the most common system tools and a bit of shell scripting) is definitely useful / necessary if you want to work with Unix systems.4) A data warehouse stores information which usually is needed for enterprise-wide strategic business decisions. A server is a machine offering software services. One kind of servers are database servers, and data warehouses usually (not always) are stored in a databases. So some sort of server is the technical basis for a data warehouse.5) Usually these two terms are identical in meaning.6) Unix is an operating system. A shell is a program which enables you to interact with a Unix system. Shell scripting means that you automate moderately complex or highly complex tasks using a programming language which is provided by the shell. Different shells offer different scripting facilities and features. Writing a shell script is a matter of programming. Your questions are by no means stupid. They just show that you still have a lot to learn, but that's ok, we all should try to learn more as long as we live. Regards,Nico

What are some basic but need to know terminal commands?

just want to know some basic commands

You can't find out for yourself? Search Google. This is not a site for Unix tutorials.

Basic Java questions

Hi.. I just joined a new company, they have developed a Java software. They have a few Sun Java Server with Tomcat, Silversteam, oracle. And their application are run on Java Web Start.
I want to learn more about Java in order to manage the server, but I have very little knowledge of it
1)What is the difference between Java Run Environment or Java Web Start??
2)When I can't access my HSBC internet banking, they told me I need to download the new Java? Is that JRE? What does it do to my computer?
3)What is the difference btw the Tomcat and Silversteam ?? Can Tomcat be installed in W2K server?
4)We can create a Jar file from the Jar class? What is Jar Class then? How to create a sample program that can be start from JWS??

Hi.. I just joined a new company, they have developed
a Java software. They have a few Sun Java Server with
Tomcat, Silversteam, oracle. And their application
are run on Java Web Start.
I want to learn more about Java in order to manage the
server, but I have very little knowledge of it
1)What is the difference between Java Run Environment
or Java Web Start?? Java Web Start is a tool that lets you manage start remote Java apps.
The Java Runtime Environment (JRE) is the interpreter through which all Java code is executed.
2)When I can't access my HSBC internet banking, they
told me I need to download the new Java? Is that JRE?
What does it do to my computer?You have to download the JRE or the Java plug-in for your browser. It does nothing special to your computer - it's just another application or plugin.
>
3)What is the difference btw the Tomcat and
Silversteam ?? Can Tomcat be installed in W2K server?
I don't know Silverstram. Tomcat is a web server written in Java.
It can run on any Java-enabled platform (i.e. any platform having the JRE installed).
4)We can create a Jar file from the Jar class? You can create a Jar using the jar tool or any zipping program, Winzip etc...
A Jar file is basically a zipped file.
What is Jar Class then?Whatever a "Jar class" is (which I don't know) it has nothing to do with the Jar files.
How to create a sample program
that can be start from JWS??Create a remote application.
You need to check some documentation and some good books.

HT1338 Itunes, Mac Book, Mac Book Pro, Ipad, iCloud, iphones,i touch, iPods purchased. My accounts have been compromised. My documents taken photos, Conatacts, Business accounts and files. They have used my ID and know my ss # everything. I need to talk t

I need to talk to someone about changing all of my accounts. A iCloud account was opened not by me and I lost 17 years of contacts. I have slowly gotten them back. My files from my Mac Book were taken and are gone. It has cost me about 60,000 dollars in business since November which has effected my staff as well. Many personal ireplacable memories of my childrens Photos were taken, Business, designs and accounting and personalFiles you name it gone or corrupted. My main PC including 4 external hard drives, then the Mac Book, My Iphones,itouch. Ipad were next and then my Mac Book pro. This is very humbling and heart felt. those who work with me have very strong beliefs, it was an internal doing or I should say someone gained or was allowed access to my home and equipment. I travel and tour and am gone quite a bit. This was and is the most difficult thing that has happened to me in a long time. In truth business and work will and can be rectified that not the point. It's how and what has been done which is the most damaging very personal almost vidictive but I will stop there. I feel so violated and saddened at the same time. I am hoping to contact someone through Apple or even an outside source to see if my files can be recouped and how to go about doing these changes all at once without all of the emails back and forth to approve changes in accounts what a pain. I want to change all accounts associated with apple. Apple ID and Pass words, I tunes ID and Pass word you name it.When I leave for work now days I have to take all of my equipment or lock things in the safe. I have an alarm system that is very good in additons to, animals still with the animals inside the motion detectors are off and in reality the damage has been done . I now this sounds crazy but I have proof of my back up files not all of them plus you can see in my documents all of my business accounts which are in orderof complition and dates are empty. My email accounts were also hacked and thru that individuals were able to change at will. When you have over 20 years of an association and relationships they know everything about someone. I do not want to press charges but I am to that point I need to bring in someone to investigate and I really do not know whom to even call. I have won awards for my work and my designs and information being taken has hurt more than words can express. I am currently out of town doing this late at night. I have changed my banking you name it. I need to have access to my computers to work but the stress of these constant changes and invasion of privacy are beyond expression. I plug in any of my usb drives and they are empty or my computers do not recognize them. I plug in my usb connector from my HP 8100 Printer with Blue tooth capabilities and it pops up and an external E drive for downloading just like an external drive. My printer acepts every imaginable portable disk on the market . Many of my usb drives are gone or have been corrupted. I have this darn air drop that goes on all the time. My computers I turn off and then they are on when I get up. I can go on and on. I live in the bay area and I am asking for help in trying to stop all of this. I will call Apple next but I wanted to put it out on this forum with the hopes of some response or input. I have all of my new and very minimal recovered information now on a web-based server which I know is safe the pass words and set up were done very discreetly (one can only hope). I apologize in advance for laying this out there like this. I am just so frustrated and because of the POSSIBLE implications makes it even harder In which I truly want to be proven wrong. I have never written or thought that I would be doing this as it is. If anything I hope some good comes out of this for someone. Bluetooth is a powerful tool this much I know now. Wow this is just simply amazing. There are 14 products I have purchased. I have been a windows person for years because of my work somethings are prapriatary to that OS but I love the Apple products. I am despratley trying not to nor will I throw in the towel. I know its a great product and its not the product. I just want to have the best opotunity to recover and have control over my designs and pretty much my privacy and peace of mind not too much to ask..:-) Oh! do not get me wrong I am willing to pay for services thats not the issue here. Once again thank you for at least espressing my frustrations.
Warmest Regards,

Some comprehensive java's book?

Hello,
I was wondering does anybody can recommend to me some latest edition of some comprehensive java's book?
I'm studying from many year-two old books, and today I find one which contain significant improvement regarding the books I have.
So please, if anyone could give me some reference (book name, authors, etc...), I'll be very thankful !
