读取excle

public class  ReadExcel{

    private String filePath;



    private List<String[]> list = new ArrayList();

    public ReadExcel(String filePath){
        this.filePath = filePath;
    }

    public List<String[]> readExcel() throws IOException, BiffException{
        //创建输入流  
        InputStream stream = new FileInputStream(filePath);
        //获取Excel文件对象  
        Workbook  rwb = Workbook.getWorkbook(stream);
        //获取文件的指定工作表 默认的第一个  
        Sheet sheet = rwb.getSheet(0);
        //行数(表头的目录不需要，从1开始)  
        for(int i=0; i<sheet.getRows(); i++){
            //创建一个数组 用来存储每一列的值
            String[] str = new String[sheet.getColumns()];
            Cell cell = null;
            //列数  
            for(int j=0; j<sheet.getColumns(); j++){

                cell = sheet.getCell(j,i);
                str[j] = cell.getContents();
            }
            //把刚获取的列存入list
            list.add(str);
        }
        return list;
    }

                System.out.print(str[j]+'\t');
            }
            System.out.println();
        }
    }
