A. You want to write a program in which you need to refer to the InetAddress of the computer you are working with. Write a statement in Java to create the corresponding object. B. Write a statement in Java to create a socket address bound to the local host and the ephemeral port number 56000. […]

A. In Figure 11.3, assume that the request is a URL to retrieve a picture. How isthe URL stored in the recvBuff? B. Write a statement in Java to extract the port number of an InetSocketAddress named sockAd. C. What is the difference between the DatagramSocket class and the Socket class in Java? D. What

A. Write a statement in Java to create a socket address bound to the local host and the HTTP server process. B. The DatagramPacket class has two constructors (see Table 11.7). Which constructor can be used as a sending packet? C. The DatagramPacket class has two constructors (see Table 11.7). Which constructor can be used

A. Write a statement in Java to create a socket address bound to InetSocket-Address addr and the TELNET server process. B. Write a statement in Java to extract the InetAddress of an InetSocketAddress named sockAd. C. A socket address is the combination of an IP address and a port number that defines an application program

A.Write a method in Java to extract the IP address (without the prefix) as a string in dotted-decimal notation from a string representing the CIDR notation (“x.y.z.t/n”). B. Write a method in Java to accept a string representing an IP address in the form “x.y.z.t” and change it to an unsigned integer. C. Write a

A. In Figure 11.5, how does the client create the input and output streams to communicate with the client? Q11-29. Explain how a UDP client program (Table 11.8) sleeps until the response comes from the server. B. How is a Socket object in a TCP client (Figure 11.5) created and destroyed? C. Write a method

A. One says that in network programming a socket should be at least bound to a local socket address. The first constructor of the DatagramSocket class (see Table 11.6) has no parameters. Can you explain how it is bound to the local socket address when used at the client site? B. We have input stream

A. Write a method in Java to change an integer representing a prefix to an unsigned 32-bit integer representing the numeric mask.B. Repeat Example 11.4 using the service of TCP. C. Repeat Problem P11.9 using the concurrent approach. D. Write a method in Java to find the last address in the block when one of

A.Write a method in Java to change an unsigned 32-bit integer representing a mask to an integer representing a prefix (/n). B. Write a method in Java to find the first address (network address) in the block when one of the addresses in the block is given as a string representing a CIDR notation. C.

A. Write a method in Java to find the size of a block when one address in the block (in CIDR notation) is given. B. Write a method in Java to find the range of addresses when the beginning and the ending addresses are given. C. Repeat Example 11.4 using the concurrent approach.
