I must change Double format from dot to comma. I try this:
DecimalFormat df = new DecimalFormat("#,00",
DecimalFormatSymbols.getInstance(Locale.GERMANY));
selectedSheet.addCell(new Number(selectedCellColumn,
selectedCellRow,
Double.valueOf(df.format(value)));
but it`s not working. Have you got any ideas how you can change a dot to a comma?
For (i guess) ApachePOI library to set a different CellUnitStyle use this:
CellStyle unitStyle = workbook.createCellStyle();
unitStyle.setDataFormat((short) BuiltinFormats.getBuiltinFormat("#,##0.00"));
cell.setCellValue(value);
cell.setCellStyle(unit);
Following Formats are builtin available: ApachePOI builtin Formats
new Number()
- I assume this takes double as the third argument? In that case, formatting the double value before you pass it in there is impossible, you need to set the format on how the sheet will display numbers in the cell formatting settings.
Or is the problem that you have a string like "5,3" and want to convert it to double? It looks like the varaible value
already has a double value in it.
You have a symbol table in the java doc of DecimalFormat
:
Symbol Location Localized? Meaning
------------------------------------------
0 Number Yes Digit
# Number Yes Digit, zero shows as absent
. Number Yes Decimal separator or monetary decimal separator
- Number Yes Minus sign
, Number Yes Grouping separator
etc...
You were using the grouping separator ,
but you wanted to use the decimal separator .
, so change your string from #,00
to #.00
:
DecimalFormat df = new DecimalFormat("#.00", DecimalFormatSymbols.getInstance(Locale.GERMANY));
String format = df.format(3.23456);
System.out.println(format); // prints 3,23
Code :
double value = 123.12345;
DecimalFormatSymbols decimalFormatSymbols = DecimalFormatSymbols.getInstance(Locale.GERMANY);
decimalFormatSymbols.setDecimalSeparator(',');
DecimalFormat df = new DecimalFormat("#.###", decimalFormatSymbols);
System.out.println(df.format(value));
selectedSheet.addCell(new Number(selectedCellColumn, selectedCellRow, Double.valueOf(df.format(value)));
Output :
123,123
