Hi everyone, i am having a little trouble, i am relatively new to java
and I am having difficulty with a little methodology.

I am using the java excel api to import some data from excel into a
routine for some data analysis. Below is a section of the code which
at the moment imports the data into java.

//import java.io.File;
//import java.io.FileInputStream;

//import jxl.Cell;
//import jxl.Sheet;
//import jxl.Workbook;

//javac -classpath c:\jexcelapi\jxl.jar;. JET2.java
//java -classpath c:\jexcelapi\jxl.jar;. JET2
//java -Xms10m -Xmx100m -classpath jxl.jar spreadsheet.xls

//java -Xms100m -Xmx200m -classpath c:\jexcelapi\jxl.jar;. JET2

import java.io.File;
import java.util.Date;
import jxl.*;

public class JET2 {

 public static void main (String[] args){
  Workbook workbook;
    try {

    workbook = Workbook.getWorkbook(new File("c:\\Docs_2\\Dad.xls"));

    double stringa1 = 0 ;
    double stringa2 = 0 ;

    Sheet sheet1 = workbook.getSheet(0);
    Sheet sheet2 = workbook.getSheet(0);

    Cell a1 = sheet1.getCell(1,1);
    Cell a2 = sheet2.getCell(0,5);

    if (a1.getType() == CellType.NUMBER)
        {
         NumberCell fc1 = (NumberCell)a1;
         stringa1 = fc1.getValue();
        }
    if (a2.getType() == CellType.NUMBER)
        {
         NumberCell fc2 = (NumberCell)a2;
         stringa2 = fc2.getValue();
        }
        //String stringa1 = a1.getContents();
        //String stringa2 = a2.getContents();

    workbook.close();

    }// End try

        catch (Exception e){

        System.out.println("Exception thrown: "+ e);

        }// End catch

    }// End Main
}// End class Jet

Now this portion works fine, however, I want to place the import code
section into a class or a method on its own, for  a couple of reasons,
its cleaner and the routine is quite lengthy and i dont want to have a
cluttered piece of code. How do i place the code into a section on its
own that can be called simply by using something like

public class JET2 {

 public static void main (String[] args){

Import data ......(utilising the above code to import data from excel)

Do stuff with data.........(data manipulation)

}// End Main
}// End class Jet

I seem to misunderstanding something very basic or can this not be
done?
