The Code Given Below Is For Displaying All Items in JTable

 try {
                for (int r = 0; r < 100; r++) { //initializing row
                    for (int c = 0; c < 4; c++) { //initializing column
                        jTable1.setValueAt(null, r, c);
                    }
                }

                BufferedReader rdfile = new BufferedReader(new FileReader("items.txt"));

                String[] item = new String[100];
                String[] temp;

                int x = 0;  //read item
                while ((item[x] = rdfile.readLine()) != null) {
                    temp = item[x].split("\t");
                    jTable1.setValueAt((1000 + x + 1), x, 0);
                    for (int j = 1; j < 4; j++) {
                        jTable1.setValueAt(temp[j - 1], x, j);
                    }

                    x++;
                }
                rdfile.close();

            } catch (IOException e) {
            }

This module displays all the items in the table.
