Has been the connection fails completely don't know what the reason, is going to do big homework hope to have a big help to solve the

Connection code:
Package DBC.
Import the Java. SQL. Connection;
Import the Java. SQL. DriverManager;
Import the Java. SQL. SQLException;
Public class DatabaseConnection {

//define the MySQL database driver
Public static final String DBDRIVER="org. GJT. Mm. Mysql. Driver".
//define the MySQL database connection address
Public static final String DBURL="JDBC: mysql://localhost: 3306/zhbit";
//MySQL database connection user name
Public static final String DBUSER="root";
//MySQL database password
Public static final String DBPASS="ax191823503";

The Connection conn=null;//database connection

Public DatabaseConnection () {
//TODO Auto - generated constructor stub
Try {
Class.forname (DBDRIVER);
} the catch (a ClassNotFoundException e) {
//TODO Auto - generated the catch block,
e.printStackTrace();
}//load driver, there are abnormal

//connect the MySQL database, write user name and password, there are abnormal
Try {
Conn=DriverManager. GetConnection (DBURL, DBUSER, DBPASS);
} the catch (SQLException e) {
//TODO Auto - generated the catch block,
e.printStackTrace();
}//there are abnormal
}

Public Connection getConnection () {
return conn;
}

Public void the close () {
Try {
Conn. Close ();
} the catch (SQLException e) {
//TODO Auto - generated the catch block,
e.printStackTrace();
}//database closed, there are abnormal
}


Public static void main (String [] args) {
The Connection conn=null;//database connection
Try {
Class.forname (DBDRIVER);
} the catch (a ClassNotFoundException e) {
//TODO Auto - generated the catch block,
e.printStackTrace();
}//load driver, there are abnormal
//connect the MySQL database, write user name and password, there are abnormal
Try {
Conn=DriverManager. GetConnection (DBURL, DBUSER, DBPASS);
} the catch (SQLException e) {
//TODO Auto - generated the catch block,
e.printStackTrace();
}//there are abnormal
System. The out. Println (conn);
Try {
Conn. Close ();
} the catch (SQLException e) {
//TODO Auto - generated the catch block,
e.printStackTrace();
}//database closed, there are abnormal
}

}
