    Connection connection = DriverManager.getConnection("jdbc:mariadb://192.168.0.2:3306/test", "user1", "admin@123");
    Statement stmt = connection.createStatement();
    stmt.executeUpdate("CREATE TABLE a (id int not null primary key, value varchar(20))");
    stmt.executeUpdate("DROP TABLE a");
    stmt.close();
    connection.close();

mysql 5.6 和 8.0 上的用户名和密码相同
