在Java中加载和解析CSV

Question

I would like the community's thoughts on a problem. I created a save and load state in my program. When I save, I create a *.csv file which saves out the information in a certain format. When I load, it loads the parsed *.csv file. The issue is when I parse, on my second line it can have as many lines as the user wants because it's a description text box. The format of the csv is like this:

User title - 1 line

User description - any number of lines

Header -1 line

Address locations -1 line per address

Example:

Myawesometitle,

This is a description,

A very good description,

Nbr,address, city,state,zip

1,5643 marketstreet, Cincinnati, OH, 80985

2,12345 main avenue, Denver, CO, 67890

How can I get around the user description having multiple lines? I can parse by either /n or ,

Thank you,

If you are not obligated to use CSV specifically I encourage you to use JSON format, it is much more dynamic and schema free, because for example, you can use lists [] as a value, and in you case it suites perfectly to unlimited number of addresses.

For example:

{
     "User title" : "Myawesometitle"

     "User description" : "This is a description"

     "Header" : "A very good description"

     "Address locations" :
     [
          {
               "Nbr" : "1,5643"
               "address" : "marketstreet"
               "city" : "Cincinnati"
               "state" : "OH"
               "zip" : "80985"
          }, 
          {
               "Nbr" : "2,12345"
               "address" : "main avenue"
               "city" : "Denver"
               "state" : "CO"
               "zip" : "67890"
          }
    ]
}
