Question

我需要在我的java程序中读取单个单元格（例如A1）。我能够将整个内容读出到我的程序中，但我怎样才能只阅读特定的单元格呢？

import java.io.*;
import java.util.Iterator;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.xssf.usermodel.XSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;

class JavaApplication2
{
static void readXlsx(File inputFile) 
{
try 
{
    // Get the workbook instance for XLSX file
    XSSFWorkbook wb = new XSSFWorkbook(new FileInputStream(inputFile));

    // Get first sheet from the workbook
    XSSFSheet sheet = wb.getSheetAt(0);

    Row row;
    Cell cell;

    // Iterate through each rows from first sheet
    Iterator<Row> rowIterator = sheet.iterator();

    while (rowIterator.hasNext()) 
    {
            row = rowIterator.next();

            // For each row, iterate through each columns
            Iterator<Cell> cellIterator = row.cellIterator();

            while (cellIterator.hasNext()) 
            {
            cell = cellIterator.next();

            switch (cell.getCellType()) 
            {

            case Cell.CELL_TYPE_BOOLEAN:
                    System.out.println(cell.getBooleanCellValue());
                    break;

            case Cell.CELL_TYPE_NUMERIC:
                    System.out.println(cell.getNumericCellValue());
                    break;

            case Cell.CELL_TYPE_STRING:
                    System.out.println(cell.getStringCellValue());
                    break;

            case Cell.CELL_TYPE_BLANK:
                    System.out.println(" ");
                    break;

            default:
                    System.out.println(cell);

            }
            }
    }
}
catch (Exception e) 
{
    System.err.println("Exception :" + e.getMessage());
}
}

static void readXls(File inputFile) 
{
try 
{
    // Get the workbook instance for XLS file
    HSSFWorkbook workbook = new HSSFWorkbook(new FileInputStream(inputFile));
    // Get first sheet from the workbook
    HSSFSheet sheet = workbook.getSheetAt(0);
    Cell cell;
    Row row;

    // Iterate through each rows from first sheet
    Iterator<Row> rowIterator = sheet.iterator();

    while (rowIterator.hasNext()) 
    {
            row = rowIterator.next();

            // For each row, iterate through each columns
            Iterator<Cell> cellIterator = row.cellIterator();

            while (cellIterator.hasNext()) 
            {
            cell = cellIterator.next();

            switch (cell.getCellType()) 
            {

            case Cell.CELL_TYPE_BOOLEAN:
                    System.out.println(cell.getBooleanCellValue());
                    break;

            case Cell.CELL_TYPE_NUMERIC:
                    System.out.println(cell.getNumericCellValue());
                    break;

            case Cell.CELL_TYPE_STRING:
                    System.out.println(cell.getStringCellValue());
                    break;

            case Cell.CELL_TYPE_BLANK:
                    System.out.println(" ");
                    break;

            default:
                    System.out.println(cell);
            }
            }
    }

} 

catch (FileNotFoundException e) 
{
    System.err.println("Exception" + e.getMessage());
}
catch (IOException e) 
{
    System.err.println("Exception" + e.getMessage());
}
}

public static void main(String[] args) 
{
    File inputFile = new File("C://users/admin/Desktop/Content.xls");

    readXls(inputFile);

}
}

这就是我所做的，我正在阅读整个内容，但我需要一个特定的单元格

您可以使用row.getCell（）方法试试这个：

Workbook workbook = WorkbookFactory.create(yourFile.getInputstream());

 Sheet sheet = workbook.getSheet(0);//1,2,3

 Iterator<Row> rowIterator = sheet.iterator();

        while (rowIterator.hasNext()) {

            Row row = rowIterator.next();

            row.getCell(0);
            row.getCell(1);
}

如何从excel表单中读取单个单元格到java程序中，
