JDBC Driver Error in Connecting to MySQL: java.lang.ClassNotFoundException: com.mysql.jdbc.Driver

In Java, the error message "java.lang.ClassNotFoundException: com.mysql.jdbc.Driver" indicates that the MySQL Connector/J library is not present or improperly configured. Here's what you can do to resolve the issue:

Solution 1: Include MySQL Connector/J Dependency

IntelliJ:

1. Right-click on the project in the "Project Explorer."
2. Hover over "Add" and select "Library."
3. Choose "Java" and add the path to the mysql-connector-java.jar file.

Maven Project:

Add the following dependency to the pom.xml file:

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>5.1.39</version>
</dependency>

Solution 2: Manual Jar File Addition

1. Download the mysql-connector-java.jar file from the MySQL website.
2. Right-click on the project in the "Project Explorer."
3. Select "Build Path" > "Configure Build Path."
4. Click the "Libraries" tab.
5. Click "Add External JARs."
6. Choose the downloaded mysql-connector-java.jar file.

Explanation:

The exception occurs because the Java Virtual Machine cannot find the com.mysql.jdbc.Driver class, which is part of the MySQL Connector/J library. By adding the dependency or manually including the JAR file, you provide the driver class and enable the application to establish a connection to the MySQL database.
