Also problem read txt files into JTable

Question

hello,
i used the following method to load a .txt file into JTable
try{
                    FileInputStream fin = new FileInputStream(filename);
                    InputStreamReader isr = new InputStreamReader(fin);
                    BufferedReader br =  new BufferedReader(isr);
                    StringTokenizer st1 = new StringTokenizer(br.readLine(), "|");
                    while( st1.hasMoreTokens() )
                         columnNames.addElement(st1.nextToken());
                    while ((aLine = br.readLine()) != null)
                         StringTokenizer st2 = new StringTokenizer(aLine, "|");
                         Vector row = new Vector();
                         while(st2.hasMoreTokens())
                              row.addElement(st2.nextToken());
                         data.addElement( row );
                    br.close();
                    }catch(Exception e){ e.printStackTrace(); }
               //colNum = st1.countTokens();
               model = new DefaultTableModel(data,columnNames);
               table.setModel(model);but there is a problem : if cell A's location is (4,5),and its left neighbour,that is, cell(4,4) is blank (the value is ""), the the cell A's value will be displayed in cell(4,4).if cell(4,3) is also blank ,the cell A's value will be displayed in cell(4,3).that is,the non-blank value will be displayed in the first blank cell of the line.
how can i solve it?Please give me some helps or links.
Thank u very much!

Answer 1

Or, use the String.split(..) method to tokenize the data
Or, use my SimpleTokenizer class which you can find by using the search function.
