Very new in Java pls help!!!!!!

hello,
i just started to learn java and trying to do my first program, but dont know why i cant do that! it asking me to set my PATH in sdk bin folder with jdk and i dont know how to do that, couse i install it in diferent folders! im trying to set c:\jdk1.6\bin;%PATH% but writing "environment variable c:jdk1.6\bin;C:\windows\system32;C:\windows;C:\windowasystem32\wbem;C;\program files\cyberlink\power2Go\C:\sun\SDK\bin not defined" help me please!!!

- Right click 'my computer', select 'properties'.
- Click the 'advanced' tab.
- click the 'environmental variables' button
Here you will find the PATH environmental variable, most likely under system variables. Add the path to the JDK bin directory here.
Note: If you have a command prompt open while you are doing this, open a new one as the old one will not see the changes you make. To make sure the PATH is valid, open a command prompt and type:
echo %PATH%

Very New to Jave, need to do totals/subtotals

Hi, (I hope this is the right place)
I'm VERY new to Java (I mainly do wourk with php interfaces for MyAQL databases).
Up until now, there hasn't been anything I couldn't do with PHP that I needed to...
My boss recently requested subtotals/totals at various points on an input sheet. The sheet inputs numbers of people, so I'm not worried about rounding (The php already takes care of people trying to input parts of people....) or tax.
It's a rather large form (~144 lines) and the math is already in place to do the subtotaling (among other things) before entering the information into the database.
How would I go about writing script that would display sub totals, and recalculate them every time one of the boxes value's is modified?
Is this something javascript is designed to do? Is there a better language out there for this task?
I've found sites out there that have canned subtotal/total scripts, but I don't want something pre-made unless it comes with a detailed explaination of what everything does; if I'm going to maintain it, I have to understand it.
Thanks

Is this a web form? e.g. a html form with input fields?
You can add onchange or onblur events to your input fields to detect changes. Then you can use javascript to retrieve the values from the form and do the calculation.

Very New To Java

Hi, I'm very new to java - 2nd day. Trying to move from Visual FoxPro.
In testing statements to learn java, I can't seem to get java.util.Scanner.nextInt or nextDouble ... etc. to wait for a keyborad input. Is there something I have to configure before utilizing ...Scanner.nextWhatever?
I'm using the latest java (just downloaded 2 day ago) and TextPad as my editor.
Thanks you.

Hi Petes1234:
Thanks for you quick response!!!!
The following is the code very simple ... still my "Hello World!" phase of learning.
import java.util.Scanner;
public class ScannerApp
     static Scanner sc = new Scanner(System.in);
     public static void main(String[] args)
          System.out.print("Enter an integer: ");
          int x = sc.nextInt();
          System.out.println("You entered " + x + ".");
}The above code complies fine. But when I try to run it, it errors out with the following error:
Enter an integer: Exception in thread "main" java.util.NoSuchElementException
     at java.util.Scanner.throwFor(Scanner.java:838)
     at java.util.Scanner.next(Scanner.java:1461)
     at java.util.Scanner.nextInt(Scanner.java:2091)
     at java.util.Scanner.nextInt(Scanner.java:2050)
     at ScannerApp.main(ScannerApp.java:11)
See anyting I'm doing wrong here?

New 2 javamail - pls help

Hello everyone,
I'm new to Java and have a project to do for school: setting up a webmail using Java.
As I work on it, some errors appeared and I dont know their meaning or where to search their explanation:
"The exception NoSuchProviderException is not handled"
"Field type Session is missing"
"Field type Store is missing"
"Field type Folder is missing"
Thank you very much, any input would be appreciated.

Hi,
The setProvider() method in javax.mail.Session can throw an exception called NoSuchProviderException when the Provider passed to it fails to instantiate. As with all java exceptions, this must be caught in you code and can't be ignored, you might like to do some of the online tutorials on this site. This one, http://java.sun.com/docs/books/tutorial/essential/exceptions/firstencounter.html is a good start for exception handling. It looks like you have some other problems there as well. Perhaps some quality time in the tutorial section will help. :-)
Cheers,
Peter.

I am completealy new at java. HELP!!!!

K, hi, well, i am experienced in HTML and Macromedia Flash, and Game Maker 5, a shit game maker prog. Ne ways, i admire games like RuneScape and would like to know how i would get around to making one. I know that i can't just jut out and make a rs type game. But i would like to know where to start? Are there programs i need to buy or DL, or are there books? And btw, is Java like HTML where u sit in front of a notepad prog, and type? or is it like u type and see whats happening? or do u add objects and give them properties..... Its a whole lot to ask! lol, Help me out.......try to answer it all.

Joshua Bloch's Effective Java
Bert Bates and Kathy Sierra's Head First Java. This one has been getting a lot of very positive comments lately.
But i would like to know where to start? With reading the "New To Java" tutorials.
Are there programs i need to buy or DLTo start with you only need Notepad, and the JDK (AKA the Java SDK), downloadable from http://java.sun.com/j2ee/1.4/download-sdk.html
Later on, you might also want an IDE, or maybe just a better text editor. But for now, just stick with Notepad.
And btw, is Java like HTML where u sit in front of a notepad prog, and type?Mostly, after writing something (in Notepad), then compile it, then run it. And extra step than HTML has.
or is it like u type and see whats happening?You can also get interactive shells for it, but for now, do not worry about them.
r do u add objects and give them propertiesYou can get IDEs which let you work this way, but for now, do not worry about them.

Go to Start menu and select Control Panel. In the Control Panel, double click on System. In the System dialogue, choose the Advanced tab. Then click on Environmental Variables. Select Path and Edit. Put ;c:\j2sdk1.4.0\bin at the end of the Path (or c:\j2sdk1.4.0\bin;) at the start of the Path. That's it.

Totally New in Java - Please help!!

Hi Dear all,
l am totally new in Java, and l facing one problem,and really hope can get some help from yours,please!
l need to write this program:
The program should do the following:
1. Input two fields: action (action: add / delete), and account number (any
digit or character)
2. if the action is "add" then the program adds one text line to a text
file.
"New account is <account number>"
3. create the text file if it is not already exist (in c:\)
4. When program runs again with new input values, a new line will be
appended to the same file.
5. if the action is "delete" then the program finds the record and removes
the text line from the file.
My problem is :
l just know that l need to create the user interface first,but l don't know how to go on??
Would you please show me some step how to solve these problem?
Many many thanks!!
BaoBao

I don't know about Swing. I never use it.
The stuff to create and manipulate files is in the java.io package.
You'll probably want to use java.io.FileReader and java.io.FileWriter.
Note that FileWriter has a constructor that lets you append and not overwrite.
I'll start you off with a test.
public class AccountListAddTest() {
public static void main(String[] argv) {
AccountList accts = new AccountList();
accts.add("abcdefg12345"); // arg is a hypothetical account number
}Write an AccountList class that'll work if you compile and run this test. After you run this test for the first time, the file should contain the string
New account is abcdefg12345.
This test assumes that the filename is hardcoded into the AccountList class. To keep it simple, make the add method create a new appending FileWriter each time, write, then close the writer.

huh???You didn't follow the directions carefully, particularly the part about setting your classpath. You can remedy this in the short term by using the following command:
java -cp . HelloWorldAppI highly recommend you go back through the instructions, though, and follow them very carefully.

New to Java: requires help possible tutor plz read

Ok, i ma very keen to learn the basics of java, however my experience is limited. When i was studying at the university of london i completed an object orientated programming module based on the the book "javagently". Since that time i have not been programming and am really keen to get into it and make my first (simple) application. i have set up java on my pc and have done a few tutorials around but would really like a reconmendation for a good text book that can take me to this level.
Let me explain what i intend on building, i play a wargame online called "Medieval:TotalWar - Viking Invasion" basically in this game you buy units for fighting and to make them more effective you can add "valor", "weap" or "armour" all of which increase the cost of the unit. a unit has base stats for different attributes and all of these variables adjust the attributes accordingly.
All the stats for the units i have in excell and text file format, i would ideally like to have scroll down bars that let you select "unit type", "valor", "weap" and "armour" default being 0 and then the app will display all the attributes that apply to those selected options. In theory i cannot see this being too hard but i just dont know where to start.
I am looking for a good text book that would help acheive this goal and also possibly a kind person that would be able to answer my silly questions privately without me looking like a fool in front of everyone here ;) on a serious note though i am deadly serious about completing this even if it takesa few months to get a grasp, if you have any inptu whatsoever it would be greatly appreciated no matter how small it may seem. if you want to see the txt file it is available here http://kenchi.mysite.freeserve.com/VIKINGS_UNIT_PROD.TXT as an example i also can get it on an excel sheet if it is easier to handle but at moment i can just about copy a txt file let alone do anything else with it.
thanks in advance

New to java, plz help

Well I'm not that new. I've been working with java for two years using jcreator in school. Its been great, we make lots of programs and run em and stuff. But the one thing we didn't learn is how to distribute the programs to other people. For instance, if I make a program to help with math homework......and I wanna give that to my friend........i'd hafta send em the source files and they'd hafta open it up in jcreator and run it........that seems kinda not good........how do u make it into an actual thing that I can click on and it runs like any normal program (exe?)

yea, heres a lot of code that calculates the Flesch readability of a piece of writing.
