i wish this is the correct way to post the codes

where r u friends???????

You have not asked any question yet. You just dumped some code in your post. And posting in "IM-speak" won't earn you much help either.

1. you need coefficients to convert 8 currency among themselves 8*8
2. function to convert text values from JTextField to number

hi friends
first of all plz excuse my bad English...Actually English is my second language..

my question is where i should put the codes that will convert the currency? and what is the codes??

to be honest i have my friend project but i don’t wanna copy it i want to understand the codes...so plz can u give me simple codes and where i should put it??

thanks friends really u r very helpful

to be honest i have my friend project but i don’t wanna copy it i want to understand the codes...so plz can u give me simple codes and where i should put it??

What is the difference between you copying your friends code and you copying something we give you?

am sorry maybe u misunderstood me:(


friend there is big different

Copying my friends codes is easier than getting the codes from u..
i meant by simple codes. the codes that i will understand i believe that u will explain it to me...

friend i add some codes to my project but there r errors. the doctor wants every time i convert currency the history of converting should be stored in file…

here is my new codes plz run it

Streams input & output you need open in CurrencyConvertor constructor , close if you exited from program.
Interesting is , what you have in "RATES.txt". You need properly read all info from RATES.txt.

hello friends,

i just want to thank u all 4 helping me...
i submited my project today but there r still some errors in input output files...
as so as i get the right codes from the doctor i will post it 4 u friends to get benefit :) plz wish 4 me my final exams will start next week.....

Can you post the codes up sooon? I neeed some help too.

Ask a question in a new thread if you need some help. Note that "help" doesn't mean giving you code to turn in for your assignment.
