How To Add Mysql Connector To Intellij

Downloading and installing MySQL Connector/J

To download and install the MySQL Connector/J, follow these steps:

1. Go to the MySQL Connector/J download page at https://dev.mysql.com/downloads/connector/j/.
2. Click on the “Download” button for the latest version of the connector.
3. Save the downloaded file to a location on your computer.
4. Extract the contents of the downloaded file to a directory on your computer.
5. To install the connector, you will need to include the connector JAR file (mysql-connector-java-x.x.x.jar) in your classpath when compiling and running your Java code. You can do this by adding the following line to your Java code:

import java.sql.DriverManager;

6. You can also include the JAR file in your classpath by adding the following command to your command prompt or terminal before running your Java code:

java -cp mysql-connector-java-x.x.x.jar:<other_dependencies> <main_class>

Replace “mysql-connector-java-x.x.x.jar” with the actual JAR file name, and replace “<other_dependencies>” and “<main_class>” with the names of any other dependencies and the main class of your Java program, respectively.

Once you have the MySQL Connector/J installed and included in your classpath, you can use it to connect to a MySQL database from your Java code.
