How to deal with comma in quote for csv file in Java?

I am using opencsv to read csv file. Fields are separated by comma. But in one field, if it contains quote, the comma inside the quote then is not a delimiter. For example, "Hello, World".

The current opencsv cannot deal with that. How to address this problem?

update

I found that it is not the problem of comma (so far). The problem row is:...,"a children""s heart\",.... It seems to remove the quote, thus the read field becomes a children"s heart",...... and ...... represent all the following data.

It seems not the problem of opencsv, but mess of the input data.

According to the documentation, you can supply custom separator and quote characters in the constructor, which should deal with it:

CSVReader(Reader reader, char separator, char quotechar)

Construct your reader with , as separator and " as quotechar.

You can write a custom code to search through your csv file and replace all comma's that are inside quotes with a , or a special character that you can identify later and place back as a comma.
