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

public class Tutorial36 {

    public static void main(String[] args) {
        try {
            System.out.println("Tutorial 36");
            System.out.println("----------");

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

            // Read XLSX file
            System.out.println("Reading file C:\\Samples\\Tutorial04.xlsx.");
            FileInputStream file = new FileInputStream("C:\\Samples\\Tutorial04.xlsx");
            
            if (workbook.easy_LoadXLSXFile(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 Tutorial36");

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

                // Export the new XLSX file
                System.out.println("Writing file C:\\Samples\\Tutorial36 - read XLSX file.xlsx.");
                workbook.easy_WriteXLSXFile("C:\\Samples\\Tutorial36 - read XLSX file.xlsx");

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