Can someone help me to find the error?
Can someone help me to find the error? I need to read the file and recognize if the code in the file is valid. Each line will be tokenized by ";". the correct first token should be digits. my code can recognize the first line of the file and give the correct output. But when it reads the next line which has a letter "a" in the first token, it does not show anything in the output. I post the output, code and the txt file below. Thanks!
the output I got:
What file would you like to parse?
accountsFile.txt
Line7536765490;Tatiana Harrison sucessfully processed
the output I want:
What file would you like to parse.
accountsFile.txt
Line 7536765490;Tatiana Harrison successfully processed
