hai,
I could not understand how to debug the error i have now.
target
1- read the files from directory // i able ot do this part
2- for each file
for each file read the content & compare with the existing List & update the list // i able to do this part

when i try to combine both parts , i got some following error



run:
E:\java\check\100130.ixf
Error: children[i] (The system cannot find the file specified)
BUILD SUCCESSFUL (total time: 2 seconds)



i can see from the code that children[i] only gives the error when i use that in the second part of the code.

can any one help me on this??
Thanks
Priyan


the original code

thanks for the kind reply.
i was playing with this code, but i could not understand where to give the file names.
it might help me to link the directory part with this code later.

hai
any one tell me how can i append two files in java.

but these are the steps to be done:

note: directory1 & directory2 contains same files mostly

1- read the file1 from the directory1 // it is fine for me
2- read the file2 from the directory2 // it is fine for me

3- later i need to append file2 contents to the end of the file 1. // in this part i am lost with code.

thanks
