The process of setting up a Java application to communicate with an Oracle Database requires a specific bridge: the JDBC (Java Database Connectivity) driver. Specifically, you are looking for the oracle.jdbc.OracleDriver class, which is contained within the OJDBC JAR files.
Match the driver to your Oracle Database version (e.g., 19c, 21c, or 23ai).
The string oracle.jdbc.OracleDriver is the fully qualified name of the class that implements the java.sql.Driver interface.
