1. Connection management: It is important to properly manage database connections to avoid resource leaks and improve performance. Connections should be established only when needed and closed after use.
2. Statement and PreparedStatement usage: Use PreparedStatement whenever possible to prevent SQL injection attacks and enhance performance. Avoid dynamically building SQL statements using string concatenation.
3. Error handling and exception management: Properly handle exceptions and provide meaningful error messages. Use try-catch blocks to catch SQLExceptions and handle them gracefully.

Common Issues and Troubleshooting

While working with JDBC, developers may encounter various issues that can impact the performance and reliability of their applications. Some common issues include connection errors and query performance issues.

Connection errors can occur due to incorrect connection parameters, network issues, or database outages. It is vital to handle these errors gracefully by providing appropriate error messages to the user and taking necessary actions to recover or terminate the application.
