Here’s an example to show you how to connect to MySQL database via JDBC driver.

1. Download MySQL JDBC Driver

Get a MySQL JDBC driver from here -MySQL JDBC Driver Download Here

2. Java JDBC Connection Example

Code snippets to use JDBC to connect a MySQL database.
  Class.forName("com.mysql.jdbc.Driver");
  Connection connection = null;
  connection = DriverManager.getConnection(
          "jdbc:mysql://hostname:port/dbname","username", "password");
  connection.close();
See a complete example below :
File : 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!");
  }
 }
}

3. Run It

Assume JDBCExample.java is store in c:\test folder, together with 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>
