3.a: What types of Sockets are supported in the Java networking package? Which type of Socket would you recommend for a VOIP type application and a File Transfer type application? 5 MARKS b: Write a Java application that uses Stream type sockets to exchange Java Objects using object serialisation. The client side should connect to the server and send it a String object. The server should print out the String and respond to the client with a text based response encapsulated in another String Object. The client should receive the String Object from the server and print out this response. 10 MARKS c: Write another Java application with the same functionality as outlined above, you can use ByteArrayOutputStream and ByteArraylnputStream to populate and read the array associated with the DatagramPacket object. l0 MARKS 3.a: What types of Sockets are supported in the Java networking package?
