I could not understand how to debug the error i have now.
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
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.
