如何使用MS excel电子表格数据填充数组？我可以更好地利用Excel电子表格数据吗？我想制作一份动物清单（A栏）及其特征（B-E栏），每一行（2-30）是不同的动物。

 import java.io.*;
    import java.util.Iterator;

    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;

    public class ReadExcelFile {
        public static void main(String[] args) 
        {
            try {

                FileInputStream file = new FileInputStream(new File("C:/Users/hussain.a/Desktop/newExcelFile.xlsx"));
                XSSFWorkbook workbook = new XSSFWorkbook(file);
                XSSFSheet sheet = workbook.getSheetAt(0);
                Iterator<Row> rowIterator = sheet.iterator();
                rowIterator.next();
                while(rowIterator.hasNext())
                {
                    Row row = rowIterator.next();
                    //For each row, iterate through each columns
                    Iterator<Cell> cellIterator = row.cellIterator();
                    while(cellIterator.hasNext())
                    {
                        Cell cell = cellIterator.next();
                        switch(cell.getCellType()) 
                        {
                            case Cell.CELL_TYPE_BOOLEAN:
                                System.out.println("boolean===>>>"+cell.getBooleanCellValue() + "\t");
// write hibernate lines here to store it in your domain
                                break;
                            case Cell.CELL_TYPE_NUMERIC:
                                System.out.println("numeric===>>>"+cell.getNumericCellValue() + "\t");
// write hibernate lines here to store it in your domain
                                break;
                            case Cell.CELL_TYPE_STRING:
                                System.out.println("String===>>>"+cell.getStringCellValue() + "\t");
// write hibernate lines here to store it in your domain
                                break;
                        }
                    }
                    System.out.println("");
                }
                file.close();
            } catch (FileNotFoundException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }

    }

而不是打印这些行，您可以将它们存储在任何适合您需要的集合对象中
