Super CSV and Grouping Separators

Tag: java,bigdecimal,supercsv

We are trying to read a file that contains numbers in the following format: 123.456,78 (according to Wikipedia this is usual for some countries - e.g. Germany).

Super CSV is configured to parse the column as BigDecimal: new ParseBigDecimal(new DecimalFormatSymbols(GERMANY)).

That works well for numbers below 1k, but the grouping separator is not handled properly: '1.999,00' could not be parsed as a BigDecimal.

I've seen that it is possible to write a custom cell processor, but perhaps someone knows if there is an easier way or if this is a known bug in Super CSV.

UPDATE:

Super CSV has integrated that feature and released it with version 2.2.0. It will work for all grouping separators that are supplied via the DecimalFormatSymbols parameter.

Best How To :

ParseBigDecimal (prior to 2.2.0) only uses the decimal separator from the supplied DecimalFormatSymbols (not the grouping separator). It's not a bug, just a limitation of the current implementation.

You can chain a StrReplace before the ParseBigDecimal (i.e. replace "." with "") and that should fix your problem (quickly).

I think that ParseBigDecimal should actually do this for you. UPDATE: And so does it since version 2.2.0.

Like you said, you can always write your own cell processor too :)

setOnClickListener error Null object

java,android

After super.onCreate(savedInstanceState); insert setContentView(R.layout.YourLayout); you need to make a request to a server in another thread. It might look like public class LoginTask extends AsyncTask<Void, Void, String>{ private String username; private String password; private Context context; public LoginTask(Context context, String username, String password) { this.username = username; this.password = password;...

It's not possible to do this using only the ArrayList.
