Class Declaration

[michael@xxxxxxxxxxxxxxxxxx]

Ok...I'm confused...

In RPG, I declare all my prototypes in my D specs. I'd like to do the
same thing with Java. So I have some code that looks like this:

 public class MakeXLS { 
     public static void main (String[] args) 
        {
        MakeXLS t = new MakeXLS();        
        t.readCSVFile();
        t.fillXLS();
                ...
But now I want to use fillXLS() inside of readCSVFile(). Why can't I
just have the line t.fillXLS() inside of readCSVFile()? Is it because
variable t is not global? I get this error instead:

javac -classpath /OpenSource/jexcelapi/jxl.jar MakeXLS.java
MakeXLS.java:58: cannot resolve symbol                     
symbol  : variable t                                       
location: class MakeXLS                                    
        t.fillXLS();                                       
        ^                                                  
1 error                                                    
$

TIA...
