jdbc 初始化及插入语句

public class initDB {
static String url = "jdbc:mysql://localhost:3306/news?useUnicode=true&characterEncoding=gbk" ;    //news代表本地创建好的表 ?useUnicode=true&characterEncoding=gbk设置输入流的编码，否则输入数据库的字符串会成乱码

static String password = "123456" ;
static String sql;

static Connection con;
static PreparedStatement stmt;
public  static void init(){

//初始化加载MySql的驱动类
Class.forName("com.mysql.jdbc.Driver") ;
//建立连接

} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
System.out.println("找不到驱动程序类 ，加载驱动失败！");
e.printStackTrace();
} catch (SQLException e) {
// TODO Auto-generated catch block
System.out.println("数据库连接失败！");
e.printStackTrace();
}
}

public static void insertNews(String Url,String NewsTitle,String NewsText,String Img,int Level,String Div){
//构造sql语句
sql="INSERT INTO news (Url,NewsTitle,NewsText,Img,Level,Newsdiv) values(?,?,?,?,?,?)" ;

//updata
