What is MySQL Connector/J and why do you need it?
MySQL Connector/J is a JDBC driver for MySQL
JDBC stands for Java Database Connectivity, which is a standard API (Application Programming Interface) that allows Java applications to access various types of databases. A JDBC driver is a software component that implements the JDBC API for a specific database. MySQL Connector/J is the official JDBC driver for MySQL, which means that it is developed and maintained by the MySQL team.
MySQL Connector/J enables Java applications to communicate with MySQL databases
By using MySQL Connector/J, you can establish a connection between your Java application and your MySQL database server, execute SQL statements, query data, perform transactions, handle errors, and more. MySQL Connector/J supports all the features and functionality of MySQL, including stored procedures, triggers, views, functions, user-defined types, etc.
MySQL Connector/J supports both JDBC and X DevAPI
MySQL Connector/J 8.0 is the latest version of the driver, which supports both JDBC and X DevAPI. JDBC is the traditional way of accessing relational databases using SQL statements. X DevAPI is a new way of accessing document-oriented databases using JSON documents and CRUD (Create, Read, Update, Delete) operations. MySQL 8.0 introduced a new document store feature that allows you to store and manipulate JSON documents in MySQL databases. By using X DevAPI, you can take advantage of this feature and work with both relational and document data in MySQL.

How to download MySQL Connector/J 64 bit?
Choose the right version of MySQL Connector/J for your MySQL and Java versions
Before you download MySQL Connector/J, you need to make sure that you choose the right version of the driver that matches your MySQL and Java versions. For example, if you are using MySQL 8.0 and Java 11, you should use MySQL Connector/J 8.0.32, which is the latest GA (General Availability) release as of May 2021. You can check the compatibility matrix of MySQL Connector/J .
Download MySQL Connector/J from the official website or a trusted source
The best way to download MySQL Connector/J is from the official website of MySQL . You can choose the operating system and platform that you are using, and then download the zip file that contains the driver. Alternatively, you can also download MySQL Connector/J from other trusted sources, such as Maven Central Repository or Oracle Software Delivery Cloud.
Verify the integrity of the downloaded file
After you download the zip file that contains MySQL Connector/J, you should verify its integrity by checking its MD5 or SHA256 checksum. You can find the checksum values on the download page of MySQL Connector/J. You can use a tool such as MD5 & SHA Checksum Utility or HashTab to compare the checksum values and make sure that the file is not corrupted or tampered with.
How to install MySQL Connector/J 64 bit?
Extract the downloaded file to a suitable location
Once you have verified the integrity of the downloaded file, you can extract it to a suitable location on your system. For example, you can extract it to C:\Program Files\MySQL\Connector.J 8.0 on Windows or /usr/local/mysql-connector-java-8.0 on Linux. You can use a tool such as WinZip or 7-Zip to unzip the file.
Add the mysql-connector-java-8.0.32.jar file to your classpath
The next step is to add the mysql-connector-java-8.0.32.jar file to your classpath, which is a list of directories and files that Java uses to find classes and resources. There are different ways to do this, depending on your development environment and preferences. For example, you can:
Copy the jar file to the lib directory of your Java project or application.
Set the CLASSPATH environment variable to include the path of the jar file.
Use the -cp or -classpath option when running your Java program from the command line.
Use an IDE (Integrated Development Environment) such as Eclipse or NetBeans and add the jar file as a library or dependency.
You can find more details on how to set the classpath .
Test the connection to your MySQL database using a sample Java program
The final step is to test the connection to your MySQL database using a sample Java program. You can use the following code snippet as an example, which connects to a MySQL database named testdb on localhost using the username root and password root, and prints some information about the connection:
import java.sql.Connection; import java.sql.DriverManager; import java.sql.SQLException; public class TestConnection public static void main(String[] args) // The connection URL for MySQL Connector/J 8.0 String url = "jdbc:mysql://localhost:3306/testdb?user=root&password=root"; try // Load the MySQL Connector/J driver Class.forName("com.mysql.cj.jdbc.Driver"); // Establish a connection to the database Connection conn = DriverManager.getConnection(url); // Print some information about the connection System.out.println("Connected to MySQL database: " + conn.getCatalog()); System.out.println("Driver name: " + conn.getMetaData().getDriverName()); System.out.println("Driver version: " + conn.getMetaData().getDriverVersion()); // Close the connection conn.close(); catch (ClassNotFoundException e) // Handle the exception if the driver is not found e.printStackTrace(); catch (SQLException e) // Handle the exception if the connection fails e.printStackTrace();
If everything works fine, you should see an output similar to this:
Connected to MySQL database: testdb Driver name: MySQL Connector/J Driver version: mysql-connector-java-8.0.32 (Revision: 6d4eaa273bc181b4cf1c8ad0821a2227f116fedf)
Congratulations! You have successfully downloaded and installed MySQL Connector/J 64 bit on your system.
