帮我用java写一个读取excel美航数据的方法

以下是一个读取Excel美航数据的Java方法的示例代码：

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;

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 ReadExcelData {

    public static List<String[]> readExcelFile(String filePath) {
        List<String[]> data = new ArrayList<String[]>();
        FileInputStream inputStream = null;
        Workbook workbook = null;
        try {
            File file = new File(filePath);
            inputStream = new FileInputStream(file);

            // Create Workbook instance holding reference to .xlsx file
            workbook = new XSSFWorkbook(inputStream);

            // Get first/desired sheet from the workbook
            Sheet sheet = workbook.getSheetAt(0);

            // Iterate through each rows one by one
            Iterator<Row> rowIterator = sheet.iterator();
            while (rowIterator.hasNext()) {
                Row row = rowIterator.next();
                String[] rowData = new String[7];
                // For each row, iterate through all the columns
                Iterator<Cell> cellIterator = row.cellIterator();
                int i = 0;
                while (cellIterator.hasNext()) {
                    Cell cell = cellIterator.next();
                    // Check the cell type and format accordingly
                    switch (cell.getCellType()) {
                    case Cell.CELL_TYPE_NUMERIC:
                        rowData[i] = String.valueOf(cell.getNumericCellValue());
                        break;
                    case Cell.CELL_TYPE_STRING:
                        rowData[i] = cell.getStringCellValue();
                        break;
                    }
                    i++;
                }
                data.add(rowData);
            }
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            try {
                if (workbook != null) {
                    workbook.close();
                }
                if (inputStream != null) {
                    inputStream.close();
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        return data;
    }

    public static void main(String[] args) {
        String filePath = "C:\\Users\\user\\Desktop\\American-Airlines.xlsx";
        List<String[]> data = readExcelFile(filePath);
        for (String[] rowData : data) {
            for (String cellData : rowData) {
                System.out.print(cellData + "\t");
            }
            System.out.println();
        }
    }
}

该方法使用Apache POI库来读取Excel文件。在这个例子中，我们假设Excel文件在本地计算机上的路径为"C:\Users\user\Desktop\American-Airlines.xlsx"。该方法将Excel文件的数据读取到一个字符串数组列表中，每个数组表示Excel文件中的一行数据。在main()方法中，我们遍历这个列表并打印出每一行数据。
