Exception in thread "main" java.lang.RuntimeException: java.sql.SQLException: No suitable driver found for

This error message usually occurs when the JDBC (Java Database Connectivity) driver is not properly installed or configured in the Java program. The JDBC driver is needed to establish a connection between the Java program and the database.

To fix this error, you should make sure that the JDBC driver is properly installed and added to the classpath of your Java program. You can do this by following these steps:

1. Download the JDBC driver for your database (e.g. MySQL, Oracle, etc.) from the vendor's website.
2. Extract the JDBC driver file and copy it to a suitable location in your project directory.
3. Add the JDBC driver to the classpath of your Java program. This can be done by adding the following code to your program:

Class.forName("com.mysql.jdbc.Driver");

Replace "com.mysql.jdbc.Driver" with the appropriate driver class for your database.

4. Establish a connection to the database using the JDBC driver. This can be done by creating a Connection object and passing the connection URL, username, and password as parameters.

Connection connection = DriverManager.getConnection(url, username, password);

Replace "url", "username", and "password" with the appropriate values for your database.

Once the JDBC driver is properly installed and configured, the "No suitable driver found" error should be resolved.
