Preface

This module is one in a collection of modules designed for teaching INEW 2338 Advanced Java (Web) at Austin Community College in Austin, TX.

This module contains review questions and answers keyed to the module titled Java4630: The InetAddress Class in the Network Programming sub-collection.

Once you study that module, you should be able to answer the review questions in this module.

The questions and the answers in this module are connected by hyperlinks to make it easy for you to navigate from the question to the answer and back again.

Questions

Question 1

True or False?

The Java InetAddress class can be used to find the IP address corresponding to a domain name .

Go to answer 1

Question 2

True or False?

Many hosts have multiple IP addresses. To accommodate this, the InetAddress class provides a method named getByName that can be used to get an array of references to InetAddress objects representing IP addresses assigned to the host.

Go to answer 2

Question 3

True or False?

The getByName method of the InetAddress class returns a reference to an InetAddress object representing the host whose domain name is passed as a parameter to the method.

Go to answer 3

Question 4

True or False?

The getLocalHost method of the InetAddress class returns a reference to an array of InetAddress objects representing all of the computers on the local area network.

Go to answer 4

Question 5

True or False?

There is a one-to-one correspondence between IP addresses and domain names.

Go to answer 5

Question 6

True or False?

Every computer on the Internet must have a unique IP address, but multiple computers can have (or can respond to) the same domain name.

Go to answer 6

Question 7

True or False?

The computer that you are using to read this module online also has an IPaddress and a name. The IP address, the name, and perhaps some other things as well are grouped together under something commonly referred to as localhost . In other words, the IP address of your localhost is the IP address of the computer that you are using to read this module.

Answers

Answer 7

True.

Go back to Question 7

Answer 6

True.

Go back to Question 6

Answer 5

False. There is not necessarily a one-to-one correspondence between IP addresses and domain names. In fact there can be a many-to-one correspondencebetween the two.

Go back to Question 5

Answer 4

False. The getLocalHost method of the InetAddress class returns a reference to an InetAddress object representing the local host computer.

Go back to Question 4

Answer 3

True.

Go back to Question 3

Answer 2

False. Many hosts have multiple IP addresses. To accommodate this, the InetAddress class provides a method named getAllByName that can be used to get an array of references to InetAddress objects representing all (or at least some) of the IP addresses assigned to the host.

Answer 1

True.
