// siddhu vydyabhushana // 4 comments
Here’s an example to show you how to connect to MySQL database via a JDBC driver. First, get a MySQL JDBC driver from here -MySQL JDBC Driver Download Here.

1. Java JDBC connection example

Code snippets to use a JDBC driver to connect a MySQL database.
Class.forName("com.mysql.jdbc.Driver");
Connection conn = null;
conn = DriverManager.getConnection("jdbc:mysql://hostname:port/dbname","username", "password");
conn.close();
See a complete example below :
JDBCExample.java
package com.mkyong.common;
 
import java.sql.DriverManager;
import java.sql.Connection;
import java.sql.SQLException;
 
public class JDBCExample {
 
  public static void main(String[] argv) {
 
 System.out.println("-------- MySQL JDBC Connection Testing ------------");
 
 try {
  Class.forName("com.mysql.jdbc.Driver");
 } catch (ClassNotFoundException e) {
  System.out.println("Where is your MySQL JDBC Driver?");
  e.printStackTrace();
  return;
 }
 
 System.out.println("MySQL JDBC Driver Registered!");
 Connection connection = null;
 
 try {
  connection = DriverManager
  .getConnection("jdbc:mysql://localhost:3306/mkyongcom","root", "password");
 
 } catch (SQLException e) {
  System.out.println("Connection Failed! Check output console");
  e.printStackTrace();
  return;
 }
 
 if (connection != null) {
  System.out.println("You made it, take control your database now!");
 } else {
  System.out.println("Failed to make connection!");
 }
  }
}

2. Run it

Assume JDBCExample.java is store in c:\test folder, along with the MySQL JDBC driver
C:\test>java -cp c:\test\mysql-connector-java-5.1.8-bin.jar;c:\test JDBCExample
-------- MySQL JDBC Connection Testing ------------
MySQL JDBC Driver Registered!
You made it, take control your database now!
 
C:\test>
P.S To run this example, your need mysql-connector-java-{version}-bin.jar in your classpath.
Done.
