java实现excel表格读取数据

Java可以通过Apache POI库来实现Excel表格读取数据的功能。具体可以参考以下代码：

import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.ss.usermodel.Sheet;
import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;

public class ExcelReader {
    public static void main(String[] args) {
        String filePath = "test.xlsx";
        try (InputStream in = new FileInputStream(filePath);
                Workbook workbook = new XSSFWorkbook(in)) {
            Sheet sheet = workbook.getSheetAt(0); // 读取第一个Sheet
            for (Row row : sheet) { // 遍历每一行
                for (Cell cell : row) { // 遍历每一个单元格
                    System.out.print(cell.toString() + "\t");
                }
                System.out.println();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
