I'm trying to write a program in java which reads a file having .csv extension.




abc_{timestamp}.csv



i.e.



abc_1546473600.csv




However, I don't know what exactly the timestamp will be as the timestamp is basically the time that the data file is generated.



How can I read the file using java?

    List the files in the parent directory, find the one you want to open, and open it?

  • you're not asking how to read the file but rather how to identify it. Completely different question.

  • be clear if you need to open all or a particular file with given timestamp. you can iterate over the list of files and find the particular file and open it.

  • What format is the timestamp? Do you want something that identifies abc_(some numbers).csv? Or you want that numbers to be timestamp

  • Thank you very much for your comments. There should be only one file. But the name of file is with a timestamp which you can consider is a random number. I want to open the file but I don't know the whole name of the file name due to the number.

  • Yes we can make use of internal API, where in you need to iterate all the available files and Filter them using Regex pattern.
