 | XLSB file generated by Tutorial 29 as base template), modify
 | some data and save it to another XLSB file (Tutorial38 - read XLSB file.xlsb).
 * --------------------------------------------------------------------------- */

import java.io.FileInputStream;
import EasyXLS.*;

public class Tutorial38 {

    public static void main(String[] args) {
        try {
            System.out.println("Tutorial 38");

            // Create an instance of the class that reads Excel files
            ExcelDocument workbook = new ExcelDocument();

            // Read XLSB file
            System.out.println("Reading file C:\\Samples\\Tutorial29.xlsb.");
            FileInputStream file = new FileInputStream("C:\\Samples\\Tutorial29.xlsb");
            if (workbook.easy_LoadXLSBFile(file))
                // Get the table of data for the second worksheet
                ExcelTable xlsSecondTable = ((ExcelWorksheet)workbook.easy_getSheetAt(1)).easy_getExcelTable();
                // Write some data to the second sheet
                xlsSecondTable.easy_getCell("A1").setValue("Data added by Tutorial38");

                for (int column=0; column<5; column++)
                    xlsSecondTable.easy_getCell(1, column).setValue("Data " + (column + 1));

                // Export the new XLSB file
                System.out.println("Writing file C:\\Samples\\Tutorial38 - read XLSB file.xlsb.");
                workbook.easy_WriteXLSBFile("C:\\Samples\\Tutorial38 - read XLSB file.xlsb");

                // Confirm export of Excel file
                if (workbook.easy_getError().equals(""))
                    System.out.println("File successfully created.");
                    System.out.println("Error encountered: " + workbook.easy_getError());
            // Dispose memory
        catch (Exception ex) {
