1. Write a Copy application that does the following:
   • With two arguments, Copy file1 file2, copy file1 to file2.
   • With one argument, Copy file1, copy file1 to console output.
   • With no arguments, open the File Chooser to select a file for listing.
   Generate an error message if file1 does not exist. Generate a warning if the destination file file2 exists and provide a message box to query whether the file should be overridden (default is no).

2. Write a program to identify the components (chunks) of a RIFF file. Download riff.zip for samples of multimedia RIFF files and example programs.

3. Write a program that counts the frequency of occurrence of alphabetic characters in a group of text files. Investigate previously reported work on the frequency of occurrence of letters in the English language and compare to your results.

4. Write a program that reads an html (text) file and extracts a list of library books and due dates. Output only the names of the books and the dates. See books.zip for example files (or use your own).

5. Write a program that checks if two files are different from one another by making a byte-by-byte comparison.

6. Write a program that displays a 256-byte section of a file as (a) characters, (b) hex, (c) 16-bit integers, or (d) 32-bit integers. Provide user interface elements that select the offset into the file (default 0) and whether the file is little-endian (Intel) or big-endian (Motorola, Sun).

7. Write a program that reads a document file and fills in marked fields with field-content pairs obtained from another file.

   Example:

   	The <noun1> in <place> falls mainly on the <noun2>.
   

   where fields are obtained by random selections from:

   	noun1  rain
   	noun2  plain
   	noun1  snow
   	noun1  sleet
   	place  Spain
   	place  Dover
   	place  Ohio
   	noun2  hills
   	noun2  street
   	noun2  feet
   

   An output for this example might be:

   
   	The snow in Ohio falls mainly on the hills.
