    Unhappy If there are any field past what is expected in each record of the input file, how to ignore it.

    Hi,

    I have an delimited input file, which i read line by line to extract data.

    the Input file looks something like this:-
    Site Name,Room Number,Street Address,Town,City,State,,,,,,,,,,,,,,,,,,,,,,,
    CVS Pharmacy,,500 Troy,Latham,NY,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,
    ,,,,,,,,,,,,,
    ,,,,,,,,,,,,,,,


    The first line, is the header line.
    But there are some comma delimiters for no reason

    I need to process the data, ignoring any fields past what is expected.
    How can I do that.

    When i run the code, it gives me
    Exception: Cannot access the Drive where the Input Files existsjava.lang.ArrayIndexOutOfBoundsException: Array index out of range: 1


    I know why it is coming, because of the extra delimiters after each line and a line with just delimiters.
    What java statement will help me skip lines where there is not data and also process lines only till the data present.

    Thank You.

    You could split the String on a comma and then reverse loop over the array until you find a location that contains data. This would be the end of the record and you can ignore everything after this index.
