Jakarta_poi uses Java to read and write Excel (97-2002) files to meet most of the needs. Because there is a project to use this tool, I spent some time to translate a guide with the POI itself. There are some sections and modifications, I hope to give some people to use someone to get home help.
There are several self-projects under POI: HSSF is used to implement Excel's read and write. The following is the homepage of HSSF http://jakarta.apache.org/poi/hssf/index.html The following information is based on the following address: HTTP : //jakarta.apache.org/poi/hssf/quick-Guide.html The current version of 1.51 should be a stable version within a long time, but the hssf provided by the SAMPLE is not based on 1.51, so when used It is necessary to pay attention. In fact, several sub-projects below POI focused on different read and write Word HDF is being developed. XML's FOP (http://xml.apache.org /fop/index.html) can output PDF files, too A better tool directory: Create a Workbook Create a Sheet Create Cells Creating a Date Cells Settings Unit Format Description: The following may be required to use the following IMPORT Org.apache.poi.hssf.usermodel.hssfcell; import org.apache .poi.hssf.usermodel.HSSFCellStyle; import org.apache.poi.hssf.usermodel.HSSFDataFormat; import org.apache.poi.hssf.usermodel.HSSFFont; import org.apache.poi.hssf.usermodel.HSSFRow; import org .apache.poi.hssf.usermodel.HSSFSheet; import org.apache.poi.hssf.usermodel.HSSFWorkbook; import org.apache.poi.hssf.util.HSSFColor; create workbookHSSFWorkbook wb = new HSSFWorkbook (); // use the default Construction Method Creating WorkbookFileOutputStream Fileout = New FileOutputStream ("Workbook.xls"); // Specify file name wb.write (fileout); // Output to file fileout.close (); create a SheethssFworkBook WB = New HSSFWorkbook (); HSSFSheet S heet1 = wb.createSheet ( "new sheet"); // workbook created sheetHSSFSheet sheet2 = wb.createSheet ( "second sheet"); // workbook created another sheetFileOutputStream fileOut = new FileOutputStream ( "workbook.xls"); wb.
