Java Performance Optimization & Security Best Practices

1. Performance Optimization Techniques

Improve Java application performance through memory management, efficient coding practices, and JVM tuning.

Garbage Collection Tuning

java -XX:+UseG1GC -Xms512m -Xmx2g -XX:MaxGCPauseMillis=200

2. Security Best Practices

Secure Java applications by implementing safe coding practices, input validation, and encryption techniques.

Example: Avoiding SQL Injection

Edit Copy

PreparedStatement stmt = conn.prepareStatement("SELECT * FROM users WHERE username = ?");
stmt.setString(1, username);
ResultSet rs = stmt.executeQuery();

3. Best Practices Summary

- Monitor and profile applications regularly.
- Use secure coding practices (e.g., avoid hardcoded credentials).
- Validate all inputs and handle exceptions properly.
- Keep dependencies and libraries up to date.

4. Conclusion

Applying performance optimization and security best practices can significantly enhance the efficiency and safety of your Java applications.
