我的插入语句有什么问题？mysql java

Question

我的插入方法有什么问题？我的表有两列,名称,艺术家和时间戳,实际上,我如何将时间戳参数传递给insert语句？

ok.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {
            try {
                /*FileWriter dir = new FileWriter(nameOfSong.getText()
                        + ".txt");
                BufferedWriter buffer = new BufferedWriter(dir);
                buffer.write(nameOfSong.getText());
                buffer.newLine();
                buffer.write(artist.getText());
                buffer.newLine();
                buffer.newLine();
                buffer.write(lyrics.getText());
                buffer.close();
                */

                Statement statement = connection.createStatement();
                statement.executeUpdate("INSERT INTO lyrics1_lyrics1 VALUES(" +
                nameOfSong.getText() + ", " + artist.getText() + "");


            } catch (Exception z) {
                System.err.println("Error: " + z.getMessage());
            } 
            internalFrame.dispose();
        }
    });
)

一直用PreparedStatement.

 String sql="INSERT INTO lyrics1_lyrics1 VALUES (?,?)";
 PreparedStatement statement = connection.prepareStatement(sql);
 statement.setString(1,nameOfSong.getText());
 statement.setString(2,artist.getText());
 statement.executeUpdate();
 statement.close();
 connection.close();
