CSCI 202 homework 4

Rules of submission

This assignment must be submitted to the Moodle submission page for Homework 4 by 11:00 PM on Friday, 15 February.

In addition to the task described below, your submission must conform to the following rules.

• There must be a Home04 class within the edu.unca.cs.csci202 package.
• All of your Java program files must contain an @author field with your full name and email address, not just your userid. Your email address should be inside angle brackets (< >).
• You may submit either a single Home04.java file or a property packaged .tar.gz or .zip archive that contains a single Home04.java file. Scripts will be used to find your Home04 class.
• Your Home04 must contain a main method that accomplishes the task.

The task

Write a program that reads a URI, for example http://www.cs.unca.edu/csci202, contained on the first input line.

Your program should use a constructor for Java’s URI class to create a URI object.

If an exception is raised by the constructor, your program should print a message giving some information about that problem.

If no exception is raised, your program should print the scheme, host and path of the URI using the appropriate methods of the URI. You really don’t need to know what a scheme is. Just call the appropriate method. If any of these URI properties is missing, it should not be printed.

Examples

In this case http://www.cs.unca.edu/csci202 was the input.

  Scheme: http
  Host: www.cs.unca.edu
  Path: /csci202

  Path: homework/home04.html

Finally Not a real URI is the input.

Exception java.net.URISyntaxException: Illegal character in path at index 3: Not a real URI
