Problem with JList

[axel axek]

I am having problems reading from a JList, my application consists in adding text line by line from a text file to a JList, ..and the problem that i am facing is...how can i read elements from Jlist, character by character .... help please....

[axel axek]

this is the code that reads form txt:
where "model" is Jlist model

  try { if(grm==1) { FileReader file = new FileReader("gramatica1.txt");
            BufferedReader buff = new BufferedReader(file);
            boolean eof = false;
            while (!eof) {
                String line = buff.readLine();
                if (line == null)
                   eof = true;
                else
                    
                    model.addElement(String.valueOf(line)); 

and i have tried to read from list:
the line i'm tryng to read is something like: "S LLLL 0.2"

s1=String.valueOf(model.getElementAt(0)); //because i need only the first line here
        for(k=0;k<s1.length();k++) {
  	        ch=s1.charAt(k);    
//...........................................
for(j=1;j<model.getSize();j++) { 
        	
        	System.out.println(model.getElementAt(0)); //verifing
        	
        	s1=String.valueOf(model.getElementAt(j)); 
        	//...........
  	        
  	        k=2; //because character nr 1 is a ' '(space)  and don't need in my application
           ch=s1.charAt(k);
  	        while (ch!=' ') {
  	    	    //.....stuff
    	         k++;
    	       ch=s1.charAt(k); //and here i get some error like Exception in thread "AWT-EventQueue-0" java.lang.StringIndexOutOfBoundsException: String index out of range: 4
    	                                // don't know why
    	        
  	        }

does anybody know any alternatives to read from a JList.....or a solution here....please help
and oh yes ..i've forgot to mention that this works just fine when using java.awt.List, but when i use JList...."bang" errors
