//jdbc:[資料庫類型]://[ip地址]:[連接埠號碼]/[資料庫名]
private String url = "jdbc:mysql://localhost:3306/userdata";
private String driver = "com.mysql.jdbc.Driver";
private String user = "root";
private String pass = "root123";

try{
Class.forName("com.mysql.jdbc.Driver");//載入驅動
}
catch(ClassNotFoundException e)

e.getException();
}
//insert into [表名](列名1,列名2) values(?,?)
//[]可以省略,()不可以,有幾個列就有幾個問號
String sql = "insert into userdata.logn(user_logn,user_password) values(?,?) ";//該字串指出了SQL語句的結構
Connection cnn = DriverManager.getConnection(url,user,pass);//串連資料庫
PreparedStatement prep = cnn.prepareStatement(sql);//建立準備好的語句
String a = "asdasdasd",b="123456" ;
prep.setString(1,a );
prep.setString(2, b);
prep.executeUpdate();//將資料寫入資料庫,也有可能引發SQL異常
cnn.close();
