如何使用Java在电子表格中创建不同类型的单元格。(How to create different types of cells in a spreadsheet using Java.)

问题描述 (Problem Description)

如何使用Java在电子表格中创建不同类型的单元格。

解决方案 (Solution)

以下是使用Java在电子表格中创建不同类型单元格的程序。

import java.io.File;
import java.io.FileOutputStream;
import java.util.Date;
import org.apache.poi.xssf.usermodel.XSSFCell;
import org.apache.poi.xssf.usermodel.XSSFRow;
import org.apache.poi.xssf.usermodel.XSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
public class TypesOfCellsInExcel {
   public static void main(String[] args)throws Exception {
      //Creating a Workbook
      XSSFWorkbook workbook = new XSSFWorkbook();
      //Creating a Spread sheet
      XSSFSheet spreadsheet = workbook.createSheet("cell types");
      XSSFRow row = spreadsheet.createRow((short) 2);
      row.createCell(0).setCellValue("Type of Cell");
      row.createCell(1).setCellValue("cell value");
      row = spreadsheet.createRow((short) 3);
      row.createCell(0).setCellValue("set cell type BLANK");
      row.createCell(1);
      row = spreadsheet.createRow((short) 4);
      row.createCell(0).setCellValue("set cell type BOOLEAN");
      row.createCell(1).setCellValue(true);
      row = spreadsheet.createRow((short) 5);
      row.createCell(0).setCellValue("set cell type ERROR");
      row.createCell(1).setCellValue(XSSFCell.CELL_TYPE_ERROR );
      row = spreadsheet.createRow((short) 6);
      row.createCell(0).setCellValue("set cell type date");
      row.createCell(1).setCellValue(new Date());
      row = spreadsheet.createRow((short) 7);
      row.createCell(0).setCellValue("set cell type numeric" );
      row.createCell(1).setCellValue(20 );
      row = spreadsheet.createRow((short) 8);
      row.createCell(0).setCellValue("set cell type string");
      row.createCell(1).setCellValue("A String");
      FileOutputStream out = new FileOutputStream(new File("typesofcells.xlsx"));
      workbook.write(out);
      out.close();
      System.out.println("typesofcells.xlsx written successfully");
   }
}
