    Default How to Read data from Datasheet of an Excel sheet using Java?

    Hello,
    I wrote a code to read the data in an Excel sheet.Its working fine and i want to read the data of other sheet in same excel sheet.and i have to use that on in other function.How to do this?Can any one explain about this.
    public static Vector ReadExcel(String fileName) {
            Vector vectorData = new Vector();
            //ReadExcel R = new ReadExcel();
     
            try {
                FileInputStream fileInputStream = new FileInputStream(fileName);
     
                XSSFWorkbook ObjWorkBook = new XSSFWorkbook(fileInputStream);
     
                [B]// Read data at sheet 0[/B] [B]I want to read the data for sheet 1..and i have to use that one in other function Like displayDataExcelXLSX[/B]//
                XSSFSheet ObjSheet = ObjWorkBook.getSheetAt(0);           
                Iterator rowIteration = ObjSheet.rowIterator();
                // Looping every row at sheet 0
                while (rowIteration.hasNext()) {
                    XSSFRow Row = (XSSFRow) rowIteration.next();
                    Iterator cellIteration = Row.cellIterator();               
                    Vector CellEachRowData = new Vector();
     
                    // Looping every cell in each row at sheet 0
                    while (cellIteration.hasNext()) {
                        XSSFCell Cell = (XSSFCell) cellIteration.next();
                        CellEachRowData.addElement(Cell);
                    }
     
                    vectorData.addElement(CellEachRowData);
                }
            } catch (Exception ex) {
                ex.printStackTrace();
            }
     
            return vectorData;
        }
    I would like to use sheet1 data in this function.
    public static void displayDataExcelXLSX(Vector vectorData) {
    }

    i want to read the data of other sheet in same excel sheet
    I don't understand the question. A sheet within a sheet? Are you saying you want to read a sheet other than the one at index 0? If so, then get the sheet at the index you wish and read it as you method posted does. You may be better off creating a method which reads the sheet at a particular index and returns the data as a List - thus you can reuse this method for whatever sheet index you want.
