I am having a JTable and a MySql table.

I knew how to fill the JTable with the array data.  But how can I fill the JTable with MySql table in the backend.

Can anyone provide me some sample code...

I have done it with the below code.

But the problem is there were many many rows in the table and I don't want to show all of them at once.

I want to show only may be around 300 rows each time and have an option below the table like previous page and next page. So that on clicking the next page option it will display the next 300 rows.

How should I do this?
String driverClass = "com.mysql.jdbc.Driver";

			Class.forName(driverClass);

			String url  = "jdbc:mysql://localhost:3306/test";

			String username = "root";

			String password = "admin";



			Connection conn = DriverManager.getConnection(url,username,password);

			Statement st = conn.createStatement();

			String query = "select * from " + tableName;

			ResultSet result = st.executeQuery(query);

			ResultSetMetaData md = result.getMetaData();

			int columnCount = md.getColumnCount();



			Vector columns = new Vector(columnCount);



			//store column names

			for(int i=1; i<=columnCount; i++)

			columns.add(md.getColumnName(i));



			Vector dataV = new Vector();

			Vector row;



			//store row data

			while(result.next())

			{

			row = new Vector(columnCount);

			for(int i=1; i<=columnCount; i++)

			{

			row.add(result.getString(i));

			}

			dataV.add(row);

			}

			st.close();

			conn.close();

			

			table = new JTable(dataV, columns);

			

			 JFrame d = new JFrame(frame, false);

	         d.getContentPane().add(new JScrollPane(table));

	         d.pack();

	         d.setVisible(true);
