- Extract the contents of the downloaded file to a directory on your computer.
- 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:
- 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.
