How to provide pagination support to a JTable in Swing?

Question

I have created one GUI in Swing Java in which I have used JTable.Now I want to display next page information into it by using pagination. How should I do that ?

Answer 1

You can try with 2 query, first query is to count total rows in DB and second query is for the real data :) And for the UI side, you can try like this:

public class MainForm extends javax.swing.JFrame {
   private void initDefaultValue() {
        rowsPerPage = Integer.valueOf(cmbPageSize.getSelectedItem().toString());
        totalRows = Main.getTablePagingService().countComments();
        Double dblTotPage = Math.ceil(totalRows.doubleValue()/rowsPerPage.doubleValue());
        totalPage = dblTotPage.intValue();
        if (pageNumber == 1) {
            btnFirst.setEnabled(false);
            btnPrevious.setEnabled(false);
        } else {
            btnFirst.setEnabled(true);
            btnPrevious.setEnabled(true);
        }
        if (pageNumber.equals(totalPage)) {
            btnNext.setEnabled(false);
            btnLast.setEnabled(false);
        } else {
            btnNext.setEnabled(true);
            btnLast.setEnabled(true);
        }
        txtPageNumber.setText(String.valueOf(pageNumber));
        lblPageOf.setText(" of " + totalPage + " ");
        lblTotalRecord.setText("Total Record " + totalRows + " rows.");
        List wPComments = Main.getTablePagingService().findAllComment(pageNumber, rowsPerPage);
        jTable1.setModel(new CommentTableModel(wPComments));
        autoResizeColumn(jTable1);
    }    
    private void btnFirstActionPerformed(ActionEvent evt) {
        pageNumber = 1; initDefaultValue();
    }
    private void btnPreviousActionPerformed(ActionEvent evt) {
        if (pageNumber > 1) {
            pageNumber -= 1; initDefaultValue();
        }
    }
    private void btnNextActionPerformed(ActionEvent evt) {
        if (pageNumber 

And in service layer, you just need use limit function like this :

public List findAllComment(Integer pageNumber, Integer rowsPerPage) {
        try {
            List listWP = new ArrayList();
            preparedFindAll.setInt(1, (rowsPerPage*(pageNumber-1)));
            preparedFindAll.setInt(2, rowsPerPage);
            ResultSet rs = preparedFindAll.executeQuery();
            while (rs.next()) {
                WPComment comment = new WPComment();
                comment.setCommentID(rs.getInt("comment_ID"));
                comment.setCommentAuthor(rs.getString("comment_author"));
                comment.setCommentDate(rs.getDate("comment_date"));
                comment.setCommentContent(rs.getString("comment_content"));
                listWP.add(comment);
            }
            return listWP;
        } catch (SQLException ex) {
            Logger.getLogger(TablePagingServiceJDBC.class.getName()).log(Level.SEVERE, null, ex);
        }

        return null;
    }

    public Integer countComments() {
        try {
            Integer totalRows = 0;
            ResultSet rs = preparedCount.executeQuery();
            while (rs.next()) {
                totalRows = rs.getInt("count(*)");
            }
            return totalRows;
        } catch (SQLException ex) {
            Logger.getLogger(TablePagingServiceJDBC.class.getName()).log(Level.SEVERE, null, ex);
        }

        return 0;
    }
