Thread: Read and write in excel 2007

Hi Experts,
I am new to this forums.
I need your help. Dose any one know, how to read and write excel file using java

If speed and memory is of your concern, then you may want to check out GemBox.Spreadsheet for Java.
I have recently swiched to it do to necessity, here is a snippet of its API:

ExcelFile workbook = ExcelFile.load("Book1.xlsx");
// Iterate through sheets.
for (ExcelWorksheet worksheet : workbook.getWorksheets()) {
    // Iterate through rows.
    for (ExcelRow row : worksheet.getRows()) {
        // Iterate through cells.
        for (ExcelCell cell : row.getAllocatedCells()) {
            Object value = cell.getValue();
            CellValueType valueType = cell.getValueType();
            // ...
        }
    }
}
