How we can filling color in excel using jsp

filling color in excel using jsp

In this program we are going to create a sheet and then fill background color ,pattern and forground color in the sheet.

Code description
The package we need to import is java.io.*,java.util.* ,org.apache.poi.hssf.usermodel.HSSFSheet,org.apache. poi.hssf.usermodel.
HSSFColor,org.apache.poi.hssf.usermodel.HSSFCell,org.apache.poi.hssf.usermodel.HSSFRow,org.apache.poi.hssf.usermodel.
HSSFCellstyle and org.apache.poi.hssf.usermodel. HSSFWorkbook.

The method used in this example shift row
setFillForegroundColor(HSSFColor.ORANGE.index):
This method is used to fill the for ground color of the style sheet.

setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);:
This method is used to fill the pattern how it look like.

setFillBackgroundColor(HSSFColor.RED.index):
This method is used to fill the background color.

You can be used the following fields in place of above

The color fields are:
HSSFColor.AQUA ,HSSFColor.BLACK,HSSFColor.BLUE ,HSSFColor.BLUE_GREY,HSSFColor.BRIGHT_GREEN,HSSFColor
,HSSFColor.BROWN, HSSFColor.CORAL ,HSSFColor.CORNFLOWER_BLUE,HSSFColor.DARK_BLUE ,HSSFColor.
DARK_GREEN, HSSFColor. DARK_RED ,HSSFColor.DARK_TEAL,HSSFColor.DARK_YELLOW,HSSFColor.GOLD,
HSSFColor.GREEN , HSSFColor. GREY_25_PERCENT,HSSFColor.GREY_40_PERCENT ,HSSFColor.GREY_50_PERCENT,
HSSFColor.GREY_80_PERCENT ,HSSFColor.INDIGO,HSSFColor.LAVENDER ,HSSFColor.LEMON_CHIFFON,HSSFColor.
LIGHT_BLUE , HSSFColor .LIGHT_CORNFLOWER_BLUE,HSSFColor.LIGHT_GREEN ,HSSFColor.LIGHT_ORANGE,
HSSFColor. LIGHT_TURQUOISE ,HSSFColor.LIGHT_YELLOW,HSSFColor. LIME,HSSFColor.MAROON,HSSFColor.
OLIVE_GREEN ,HSSFColor.ORANGE,HSSFColor.ORCHID ,HSSFColor.PALE_BLUE,HSSFColor.PINK ,HSSFColor.PLUM,
HSSFColor.RED , HSSFColor.ROSE,HSSFColor.ROYAL_BLUE ,HSSFColor.SEA_GREEN,HSSFColor.SKY_BLUE ,HSSFColor.
TAN,HSSFColor. TEAL HSSFColor.TURQUOISE,HSSFColor.VIOLET ,HSSFColor.WHITE,HSSFColor.YELLOW

And the pattern fields are:
NO_FILL, SOLID_FOREGROUND, FINE_DOTS, ALT_BARS, SPARSE_DOTS, THICK_HORZ_BANDS, THICK_VERT_BANDS,
THICK_BACKWARD_DIAG, THICK_FORWARD_DIAG, BIG_SPOTS, BRICKS, THIN_HORZ_BANDS, THIN_VERT_BANDS, THIN_BACKWARD_DIAG, THIN_FORWARD_DIAG, SQUARES, DIAMONDS .

In this example we are creating the sheet and four style sheet .Then we set the fill color of forground ,pattern and background color .Then at last we add the style sheet into cellls and finally we add the cells into sheet. The output of the example is shown below

The code of the program is given below:

  HSSFWorkbook hwb = new HSSFWorkbook();

  HSSFSheet sheet = hwb.createSheet("new sheet");

  HSSFCellStyle style1 = hwb.createCellStyle();

  HSSFCellStyle style2 = hwb.createCellStyle();

  HSSFCellStyle style3 = hwb.createCellStyle();

  HSSFCellStyle style = hwb.createCellStyle();

  for(int i=0;i<50;i++){

    HSSFRow row = sheet.createRow((short) 0+i);

    HSSFCell cell = row.createCell((short) 0);

    cell.setCellValue(1);

        style.setFillBackgroundColor(HSSFColor.AQUA.index);

     
  style.setFillPattern(HSSFCellStyle.BIG_SPOTS);

     
  style.setFillForegroundColor(HSSFColor.ORANGE.index);

    style.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);

    HSSFCell cell4 = row.createCell((short) 1);

    cell4.setCellValue(2);

    HSSFCell cell1 = row.createCell((short) 2);

    cell1.setCellValue(3);

    HSSFCell cell2 = row.createCell((short) 3);

    cell2.setCellValue(4);

    HSSFCell cell3 = row.createCell((short) 4);

    cell3.setCellValue(5);

    style.setFillBackgroundColor(HSSFColor.AQUA.index);

    style.setFillPattern(HSSFCellStyle.BIG_SPOTS);

     
  style1.setFillForegroundColor(HSSFColor.ORANGE.index);

    style1.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);

    style2.setFillBackgroundColor(HSSFColor.RED.index);

        style2.setFillPattern(HSSFCellStyle.BIG_SPOTS);

     
  style3.setFillForegroundColor(HSSFColor.GREEN.index);

    style3.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);

     
  style4.setFillForegroundColor(HSSFColor.BLUE.index);

    style4.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);

     
  cell.setCellStyle(style);

    cell1.setCellStyle(style1);

    cell2.setCellStyle(style2);

    cell3.setCellStyle(style3);

    cell4.setCellStyle(style4);

  } 

   FileOutputStream fileOut = new FileOutputStream

("C:\\excel\\fillsColor.xls");

    hwb.write(fileOut);

    fileOut.close();

    out.println("Your excel file has been generated");

     } catch ( Exception ex ) {         

        }%>

The output of the program is given below:
