Java IO Help Please
Hi,
I am new to reading and writing varibles to a file from a GUI Application.
What I am trying to do is make an object (that only contains some varibles) and have my main program take the object and write its varibles to a file (doesn't matter what type).
Then I also want to be able to read the file and put the varibles to where they were. I really have no clue how to do this.
Could you point me in the right direction of where to learn to do this?
Code Samples and tutorials would be helpful
Ryltar
Depending on what you are trying to accomplish, you may be able to serialize the object:

class HelloARP {
public static void main (String[] arguments) {
System.out.println("What's good ARP?");
- all responses and help are welcomed. Thank you ahead of time for anyone that can help me get started.Hi
First of all uninstall your current JDK installation, if you can get to the registry delete the registry entries for the old version of java which was there on your machine.
Now do a fresh install of your j2sdk1.4.1, make sure that you will install the JRE with the J2SDK1.4.1.
Once you are done, set your classpath in autoexec.bat if you are using Windows 95/98
or set your environment variables if you are using Win NT/2000/XP.
If using solaris or other unix flavors see the included installation instructions provided.
Let me if you face the same problem.
Thanks

}I decided to post my program on here because I remember how hard it was to get it to work, and I don't want people to go through the same problems... just don't use it to compete against me in the Intel Science and Engineering Fair and/or the Intel Science Talent Search ;-) then I'll be mad. Other than that, have fun!

Hi all,
I need help with java code please.
My source is a csv file and target is multiple idocs.
Source file structure is as follows:
Header (field 1, field 2, ........ field 10)
Item 1a (field 1, field 2, field 3, ......... field 180)
Item 1b (field 1, field 2, field 3, ......... field 180)
Item 2a (field 1, field 2, field 3, ......... field 180)
Item 2b (field 1, field 2, field 3, ......... field 180)
Item na (field 1, field 2, field 3, ......... field 180)
Item nb (field 1, field 2, field 3, ......... field 180)
First line is header. Second is VAT line. Third is Price line for that VAT. Now VAT and Price lines repeat. There need not be VAT line for non-European countries. So a VAT line may or may not preceed a Price line.
For example: the lines can be like:
Header
VAT1
Price1
VAT2
Price2
Price3
1) Now, it should produce 3 idocs like:
Header, VAT1, Price1
Header, VAT2, Price2
Header, Price3
2) One idoc should be created per a pair of VAT and Price lines and they will be identified by a co-relation of a particular field. So first I have to sort all the lines based on this field value. Then I have to read the lines in pairs. If no Vat line, I should just read the Price item and produce an idoc.
Can you please help me with the java code for this?
Many thanks in advance.
Ramesh.Many thanks Ram.
The reason for thinking to go for java mapping is that there is no keyfield for price line. The source file is a pipe delimited csv file. There is a keyfield for VAT line. The same field will be empty for the Price line. I am trying to ask them to at least provide a space for that field between the pipes for price line so that I can use in FCC. It looks like they can't modify the source file.
Any inputs please?
Regards.
Ramesh. -
Very simple java project (help please)
Hello. For a project I have to somehow use MouseListener to make something. My idea was to have a rectangle in which a circle (hockey puck) follows the user's mouse and whenever the user places the circle into a certain area the count goes up by one (like a game of hockey). If someone could give me some idea as to where I should start it would be greatly appreciated.
My thanksThis is alwyas [a good place to start|http://java.sun.com/developer/onlineTraining/] when you don't have a clue what's going on, and here if you need specifics on MouseListener. And to get movement, then you'll probably want to look here.
Once you have some code and specific questions, literally almost everyone on here will be willing to help you further along the way. When you post code, please use code tags. -
