java程序，要连mysql ，请班我把下面的连ACCESS数据库的代码改成用MYSQL数据库连接的吧~！！！

public void insertRecord()
{
if(tf1.getText().equals("")||tf2.getText().equals("")||tf3.getText().equals("")||
tf4.getText().equals("")||tf5.getText().equals("")||tf6.getText().equals(""))
{
JOptionPane.showMessageDialog(f3,"请填写图书资料");
return;
}

try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
}catch(ClassNotFoundException e){System.out.println("加载驱动程序失败!");}
try{
String url = "jdbc:odbc:driver={Microsoft Access Driver (*.mdb)};DBQ=Book.mdb";//直接使用当前类目录下的数据库文件
Connection con=DriverManager.getConnection(url);
Statement sql; String s="insert into book values('"+tf1.getText()+"','"+tf2.getText()+"','"+
tf3.getText()+"','"+tf4.getText()+"','"+tf5.getText()+"','"+tf6.getText()+"');";
//查询输入的图书号是否在数据库中存在
String query="select * from book where 图书号='"+tf2.getText()+"'";
sql=con.createStatement();
ResultSet rs=sql.executeQuery(query);//返回查询结果集
boolean moreRecords=rs.next();//判断结果集是否有数据
if(moreRecords)
{
JOptionPane.showMessageDialog(f3,"图书号已经被使用，请重新输入");
con.close();
tf2.setText("");
return;
}

int insert=sql.executeUpdate(s);
if(insert==1)
{
JOptionPane.showMessageDialog(null,"图书信息录入成功！");
tf1.setText("");
tf2.setText("");

tf6.setText("");
}
}catch(SQLException g)
