Consider the following java program

Consider the following Java program: 1: public class TCPServer 2: public static void main(String argv) throws Exception ( 3: 4 5: 6: 7: 8: 9: 10: String clientSentence String capitalizedSentence ServerSocket welcomeSocket-new ServerSocket(6789); while(true) Socket connectionSocket = BufferedReader inFromClient new BufferedReader( new InputStreamReader(connectionSocket.getinputStream) DataOutputStream outTClient = new DataOutputStream( connectionSocket.getOutputStreamO); clientsentence = inFromClient.readLine(); capitalizedSentence clientSentence.toUpperCase() + , n.; outToClient.writeBytes(capitalizedSentence); 12: 13: 14: 15: 16: 17:) Question 1: Complete line 7. Question 2: Extend the server to print the IP address/port of every connecting client Use line numbers to indicate which lines should be changed/removed and where new code should be added Question 3: Assume that 3 different machines connect to the server (sequentially). As a result, how many Socket objects will be created by the server? How many TCP ports will be assigned to the server (not including the already assigned port 6789)
