This is a good Java student management system project case. Hope to help you learn it.

The Code is as follows:

 

package com.student.util;import java.sql.Connection;import java.sql.DriverManager;import java.sql.SQLException;public class DbUtil {        private String dbUrl="jdbc:mysql://localhost:3306/db_student";        private String user="root";        private String password="123456";        private String jdbcName="com.mysql.jdbc.Driver";        public Connection getCon() throws Exception{                Class.forName(jdbcName);                Connection con=DriverManager.getConnection(dbUrl, user, password);                return con;        }        public void close(Connection con)throws Exception{                if(con!=null){                        con.close();                }        }        public static void main(String[] args){                Connection con=null;                try {                        con = new DbUtil().getCon();                        System.out.println(con);                } catch (Exception e) {                        e.printStackTrace();                }finally{                        if(con!=null){                                try {                                        con.close();                                } catch (SQLException e) {                                        e.printStackTrace();                                }                        }                }        }}
