21. What are the different types of JDBC drivers? Discuss the advantages and disadvantages of each type.
    

22. What is object serialization in Java? How does it help in persisting objects?
    

23. Explain the concept of Serializable interface. How does it affect the serialization of objects?
    

24. Discuss the role of ObjectInputStream and ObjectOutputStream in the serialization process.
    

25. What is a socket in Java? Explain how client-server communication is established using sockets.
    

26. Discuss how the ServerSocket and Socket classes are used to implement client-server communication in Java.
    

27. What is the significance of input and output streams in socket programming? How do they facilitate communication between a client and server?
    

28. Explain the concept of a multithreaded server in Java. How do threads improve the performance of a server application?
    

29. What is Remote Method Invocation (RMI) in Java? How does it enable communication between different JVMs?
    

30. Discuss the process of creating and using an RMI server and client. What are the essential components of RMI?
    

31. What is Java Native Interface (JNI)? How does it allow Java code to interact with native applications and libraries?
    

32. What is the Collection API in Java? Discuss the different interfaces that make up the Collection framework.
