I want to read a .CSV (comma separated file) in a particular location and see if
the format is correct. if the format is ok then ftp it to another directory or another locationYou don't specify how you want to handle the file. You can do it three ways:
1) Just read the file as is, including the delimiters, then process it.
2) Remove the delimiters from the file, then read the file and process it.
3) Parse the file using the delimiters to separate the file into tokens, then read the tokens and process them.
I'll assume that you want to do #3 above. The following code will handle CSV data that is delimited by a comma, and is either quoted or unquoted.
public class Xb
    public static void main(String[] args)
        // csv include both quoted and unquoted data
        String csv = "\"a\",\"b\",\"c\",d,e,f";
        System.out.println(csv); // so you can see the data
        String[] stArray = csv.replaceAll("\"", "").split(",");
        for (int j = 0; j < stArray.length; j++)
            System.out.println(stArray[j]);
}This is the printed output:
"a","b","c",d,e,f
a
b
c
d
e
f
Note: If you want #2 above, delete[b] .split(",") from this line:
String[] stArray = csv.replaceAll("\"", "").split(",");
